EXECUTIVE SUMMARY

The future telecommunications capacity and connectivity

requirements of the United States (US) research and development (R&D)

community raise two concerns. First, would there be adequate

privately-owned communications capacity to meet the ever-increasing

requirements of the US R&D community for domestic and international

connectivity? Second, is the method of piecemeal implementation of

communications facilities by individual researchers cost effective

when viewed from an integrated perspective?

To address the capacity issue, Contel recently completed a study

for NASA identifying the current domestic R&D telecommunications

capacity and connectivity requirements, and projecting the same to

the years 1991, 1996, 2000 and 2010. The work reported here extends

the scope of an earlier study by factoring in the impact of

international connectivity requirements on capacity and connectivity

forecasts.

Most researchers in foreign countries, as is the case with US

researchers, rely on regional, national or continent-wide networks to

collaborate with each other, and their US counterparts. The US

researchers' international connectivity requirements, therefore, stem

from the need to link the US domestic research networks to foreign

research networks. The number of links and, more importantly, the

speeds of links are invariably determined by the characteristics of

the networks being linked. The major thrust of this study,

therefore, was to identify and characterize the foreign research

networks, to quantify the current status of their connectivity to the

US networks, and to project growth in the connectivity requirements

to years 1991, 1996, 2000, and 2010 so that a composite picture of

the US research networks in the same years could be forecasted.

Considerable cost savings can be realized by implementing

research networks on an integrated rather than on a piecemeal basis

to meet individual researcher's needs. This point was vividly

demonstrated in the earlier study, and has the same implications for

international connectivity. For example, currently there are 77

links between the US and foreign research networks. We believe that

these can be consolidated into 20 links. In the year 1991, and

beyond, as the consolidation in the US and abroad progresses, the

number of links can be reduced to as few as ten (10). The new links,

no doubt would have higher speeds, but would be much more cost

efficient due to economies of aggregation.

Major findings of this study are as follows.

INTERNATIONAL RESEARCH NETWORKS

International research networks were identified and described

for the following seven areas: Worldwide, North America (excluding

the United States), Europe, Asia, Australia/Pacific, Central/South

America and Africa. There are a wide variety of research networks

throughout these areas. Also, the various nations are at different

stages in the development of such networks. A few already have

nationwide research networks, while many are just beginning to

develop their first research network. Also, a good number of

countries have little or no networking activity. The most advanced

networks, as expected, are in the more advanced, industrialized

countries, e.g., Canada, France, Germany, Japan and the United

Kingdom. Asia, Central/South America, and Africa are far behind in

network development, but interest is growing in these areas.

Some 84 research networks outside the United States were

identified. These networks are listed in Exhibit 1-2. About

three-fourths of these are national networks, and about one-fourth

are multi-nation, continent-wide or worldwide networks. About half

of the networks are in Europe, and the other half are distributed

Page xv
across the other regions. Across all 84 networks, current link

speeds range from 1.2 kilobits per second (Kbps) to 1.544 megabits

per second (Mbps). When the 84 networks are categorized by link

speeds (i.e., 1.2 Kbps to 19.2 Kbps; 48 Kbps to 768 Kbps; and 1544

Kbps or more), about half of the networks fall into the category with

the lowest link speeds, and only about ten percent have maximum links

speeds of 1544 Kbps or higher. The world-wide networks have the

lowest maximum link speed, while networks serving a single nation

have the highest maximum link speed. The networks with the highest

maximum link speeds are in North America (Canada), Europe (France)

and Asia (Japan). The networks with the lowest maximum link speeds

are in Central and South America and Africa.

CURRENT INTERNATIONAL TRAFFIC FLOW

An estimate of the current international R&D traffic flow was

derived by ascertaining the speeds of the international links between

the United States networks and the international networks.

Currently, there are 77 United States-international links, and these

links connect 22 United States cities to 48 foreign cities in 18

countries. Over half of these links are to Europe, over half

originate from two United States cities (i.e., Greenbelt, MD and

Princeton, NJ), and about half are NASA network links. The speeds of

these international links range from 9.6 Kbps to 1.544 Mbps. Over

half of the links are 19.2 Kbps or slower, and there currently is

only one 1.544 Mbps link.

FUTURE INTERNATIONAL TRAFFIC FLOW

To estimate the future international traffic flow, the future

link speeds of the international networks described above and the

future link speeds of the United States-international links were

projected. These projections were based on: Coordinating Committee

for International Research Networking (CCIRN) drafted policy, Federal

Pagc xvi
Networking Council Engineering Planning Group (FEPG) proposed policy,

CCIRN perspective on worldwide research network requirements, and

major factors affecting international network requirements. On the

basis of these policies, perspectives and factors guidelines were

developed for projecting future link speeds for the international

networks and for the international links.

The following is a summary of the projections of future

international network link speeds:

1. 1991: about half of the international networks are expected to

have only a 9.6 Kbps backbone, about thirty-five percent are

expected to have a 64 Kbps backbone, and only about fifteen

percent are projected to have a 1.544 Mbps backbone.

2. 1996: about thirty percent of the international networks are

expected to have a 64 Kbps backbone, about thirty percent are

expected to have a 1.544 Mbps backbone, and about forty percent

are projected to have a 45 Mbps backbone.

3. 2000: about thirty percent of the international networks are

expected to have a 1.544 Mbps backbone, about thirty percent are

expected to have a 45 Mbps backbone, and about forty percent are

projected to have a 1 gigabit per second (Gbps) backbone.

4. 2010: about thirty percent of the international networks are

expected to have a 45 Mbps backbone, about thirty percent are

expected to have a 1 Gbps backbone, and about forty percent are

projected to have a 5 Gbps backbone.

To develop the projections of the United States-international

links, the current 77 links were consolidated, reducing the number of

international links from 77 to 20. It should be pointed out that

these 20 links, in a final consolidation, were reduced to 10 links

when developing the future integrated research networks (IRNs) which

are discussed below. The following is a summary of the projections

of the speeds of the United States-international links before this

final consolidation:

1. 1991: link speeds of the new 10 international links range from

9.6 Kbps to 1.544 Mbps; about 40 percent of these links are

Page xvii
expected to operate at 1.544 Mbps, al_out 40 percent at 64/128

Kbps, and about 20 percentat 9.6Kbps.

2. 1996: link speeds of the new 10 international links range from

64 Kbps to 45 Mbps; about 55 percent of these links are expected

to operate at 45 Mbps, 30 pcrcent at 1.544 Mbps, and 15 at 64

Kbps.

3. 2000: link spccds of thc ncw 10 intcrnational links rangc from

1.544 Mbps to l Gbps; about 55 percent of these links are

expected to operate at l Gbps, 30 percent at 45 Mbps, and 15

percent at 1.544 Mbps.

4. 2010: link speeds of the new 10international links range from I

Gbps to 5 Gbps; about 55 percent of these links arc cxpcctcd to

operate at 5 Gbps, 30 percent at I Gbps, and 15 percent at 45

Mbps.

UPDATE OF UNITED STATES RESEARCH NETWORKS

The update of the United States research networks resulted in

very few unexpected changcs that must bc considered when describing

the new current and future IRNs. This update was presented in terms

of unexpected changes in specific U.S. rcscarch networks and in the

National Research and Education Nctwork (NREN) plans. The purpose of

this update was to determine if the IRN topology maps developed in

the previous study had to bc modified.

THE NEW INTEGRATED RESEARCH NETWORKS

The New Current Integrated Research Network

The incorporation of the current international research network

traffic flow in the new current IRN, resulted in no change in the

original current IRN domestic topology map, but suggested a need to

consolidate United States-international links. Currently, there are,

as noted above, some 77 links connecting the United States research

Page xviii
networks to research networks in countries around the world. These

links range in speed from 9.6 Kbps to 1.544 Mbps, and they connect a

TI backbone in the United States to research networks that are

located around the world and that have link speeds ranging from 1.2

Kbps to 64 Kbps.

The New 1991 Integrated Research Network

An additional consolidation of the 20 United Statesinternational links in 1991 resulted in only 10 links connecting the

United States research networks to research networks in countries

around the world. This consolidation is possible because of the

trend in the US and abroad to consolidate and interconnect networks.

Therefore, the US-international connectivity requirement reduces to

connecting major US networks to major foreign networks. In 1991,

these links are all projected to be 1.544 Mbps links except for the

two links to Mexico and Central/South America which are expected to

be 128 Kbps links and one of the two links to Asia which is expected

to be a 9.6 link. The ten links connect a T3/TI backbone in the

United States to research networks around the world that have link

speeds ranging from 9.6 Kbps to 1.544 Mbps.

The New 1996 Integrated Research Network

In 1996, only 10 links are projected (the same as projected for

1991) for connecting the United States research networks to research

networks in countries around the world. These links in 1996 are all

projected to be 45 Mbps links except for two links to Mexico and

Central/South America and one to Asia which are each expected to be

1.544 Mbps links. The ten links connect a backbone, ranging in link

speeds from 45 Mbps to 1 Gbps, in the United States to research

networks around the world that have link speeds ranging from 9.6 Kbps

to 45 Mbps.

The New 2000 Integrated Research Network

In the year 2000, the same 10 links are projected for connecting

Page xix
the United States research networks to research networks in countries

around the world. However, these links in year 2000 are all projected

to be 1 Gbps links except for two links to Mexico and Central/South

America and one to Asia which are each expected to be 45 Mbps links.

The ten links connect a backbone, ranging in link speeds from 272

Mbps to 5 Gbps, in the United States to research networks around the

world that have link speeds ranging from 9.6 Kbps to I Gbps.

The New 2010 Integrated Research Network

In the year 2010, the same 10 links are projected for connecting

the United States research networks to research networks in countries

around the world. As before, these links are expected to be

operating at higher speeds. In year 2010 they are all projected to

be 5 Gbps links except for two links to Mexico and Central/South

America and one to Asia which are each expected to be 1 Gbps links.

The ten links connect, in year 2010, a backbone, ranging in link

speeds from 1 Gbps to 25 Gbps, in the United States to research

networks around the world that have link speeds ranging from 64 Kbps

to 5 Gbps.

RECOMMENDATIONS

A consensus of academic, industry, and institutional experts

engaged in developing and operating computer research networks is

that significantly higher communications capacities will be needed in

the years to come to link researchers around the world to enable them

to collaborate in cooperative research endeavors regardless of their

physical locations. The researchers' needs for communications will

encompass accessing large data bases, linking supercomputers in a

massively paralleled configuration, and presenting simulation results

with ever-increasing resolution and clarity to permit researcher to

overcome resource limitations.

NASA needs to address several technology and policy issues in

order to translate today's vision into what some experts have called

Page xx
the "Collaboratory" of the future. Some specific recommendations are

as follows:

1. Support the development of the NREN which will improve

network performance and ubiquity for researchers and

educators.

2. Support the consolidation of U.S.-international links,

thereby increasing network performance and ubiquity

worldwide.

3. Support the development of a worldwide research and

education network (WREN), thereby improving research and

education worldwide.

4. Support the further study of both policy and technical

issues related to the implementation of the computer

research initiatives already put forth by the White House

and Congress.

5. Continue to examine NASA's own computer research network

requirements and to work to incorporate these needs in the

developmentof the NREN.

6. Review industry plans for the telecommunications

infrastructure growth, and ascertain whether researchers'

projected needs can be easily accommodated within the

industry expansionplans.

INTRODUCTION AND SUMMARY

1.1 STUDY OVERVIEW AND BACKGROUND

1.1.1 Study Overview

During the last decade, the NASA Lewis Research Center's

Communications Program has conducted a series of telecommunications

forecasting studies to project communications requirements and

trends, and to identify critical telecommunications technologies that

must be developed to meet future requirements. The Government

Networks Division of Contel Federal Systems has assisted NASA in

these studies, and the current study builds upon these earlier

efforts.

1.1.2 Study Background

The current major thrust of the NASA Communications Program is

aimed at developing the high risk, advanced communications satellite

and terminal technologies required to significantly increase the

capacity of future communications systems. Also, major new

technological, economic, and social-political events and trends are

now shaping the communications industry of the future.

Therefore, a re-examination of future telecommunications needs

and requirements is necessary to enable NASA to make management

decisions in its Communications Program and to ensure that proper

technologies and systems are addressed. This re-examination is being

accomplished through a series of studies which are helping NASA

define the likely communication service needs and requirements of the

future, and thereby, ensuring that the most appropriate technology

developments are pursued.

_ Page 1-1
The most recent study, in this series of studies, dealt with the

domestic telecommunications requirements for the U.S. research and

development community. The current study, the results of which are

summarized in this volume, extended the scope of this earlier study

by focusing on the international telecommunications requirements for

the U.S. research and development community.

1.2 METHODOLOGY

The methodology employed in this study is described below in

terms of the study purpose, the tasks performed, and the approach

used to accomplish the tasks.

1.2.1 Purpose

The purpose of this study was to assist NASA in determining the

current and future international telecommunications requirements for

the U.S. research and development community. This understanding of

international research network needs is helping NASA define the

U.S.'s future technology requirements and thereby ensuring that the

most appropriate technology developments are pursued.

1.2.2 Tasks

This study accomplished its purpose of determining current and

future international research communications needs by undertaking the

following tasks:

1. Identifying, defining and describing the international

research network community.

2. Identifying, defining and describing major research networks

outside the U.S..

3. Estimating the current and future international research

network traffic flow.

4. Identifying and describing recent unexpected changes in U.S.

research networks.

Page 1-2
5. Describing new current and future Integrated Research Networks

(IRNs).

1.2.3 Approach

To accomplish the purpose of this study, the study approach

depicted in Exhibit l-l was used. This exhibit shows the interaction

of the five major study tasks listed above. The specific approach

employed for each of these tasks issummarized below.

1.2.3.1 Identifying, Defining And Describing The International

Research Network Community.

The purpose of this task was to describe the international

research network community so that the major research networks, which

arc outside the United States and with which the United States

research networks have or may have requirements to interface, could

bc selected.

The development of the description of the international research

network community began with an initial review of the literature on

international research networks. Selected books, articles and

reports were reviewed to obtain information on the history,

development and operation of such networks. This initial review

helped structure interviews with leaders in the development of United

States research networks. From the initial review and the

interviews, preliminary information on international networks was

developed, and contacts were identified. These new contacts were

telephoned, and additional information on international research

networks was obtained.

The information collected through this series of activities was

aggregated and analyzed, and provided the basis for describing the

international research network community. Included in this

description of the international research network community are three

major summaries or outlines: a summary of the history of the

development of the international research networks, a summary of the

major organizations involved in the development and coordination of

these networks; an outline of all the significant research networks

outside the United States, and a summary of the gateways in the

United States.

1.2.3.2 Identifying, Defining And Describing Major Research Networks

Outside The U.S..

The major intent of this task was to present a picture of the

level of research network development around the world, so that the

current and future levels of United States/International research

network traffic flow could be estimated. To accomplish this purpose

the completion of two major activities was required: selecting the

networks and then describing the networks.

Since the major intent was to present a picture of the level of

research network development around the world, a comprehensive

picture of a wide variety of network efforts had to be developed.

Therefore, the criteria used to select the international research

networks, had to result in the selection of networks that varied on

such elements as size (i.e., extent of coverage), link speed, and

connectivity. Consequently, a network was selected if information on

the network was accessible and if it met one or more of the following

criteria:

1. It is a major worldwide network.

2. It is a major multi-nation network.

3. It is the only multi-nation network serving a region of the

world.

4. It is a major national network.

5. It is the only national network for a country.

6. Within a nation, it is an advanced regional network.

7. Within a nation, or among nations, it is, or was, an important

experimental network.

8. It has an international link with the United States.

Page 1-5
Once the international networks were selected, describing them

involved collecting additional information, drafting summaries of

each network, and reviewing and modifying the summary descriptions.

Information on the selected international networks was collected

through interviews and telephone calls with research network leaders

and managers. These descriptions of the selected international

research networks were used in subsequent tasks to estimate the

future topologies of these international networks and to identify

current United States/internationallinks.

1.2.3.3 Estimating The Current And Future International Research

Network Traffic Flow.

The purpose of this task was to develop estimates of the current

and future traffic flows, between the United States research networks

described in the previous study on domestic research network

requirements and the international research networks (i.e., those

outside the United States)selectedand described in this study.

Estimating the current and future traffic flows between United

States and international research networks included the following

activities: selecting the measure of traffic flow; identifying the

current international links and specifying their speeds; determining

the current link speeds of the selected international networks;

estimating the future link speeds of these international networks;

and projecting the future link speeds of the internationallinks.

Based on a review of information on the selected international

networks and on the international links, it was determined that

installed capacity would bc the best measure of traffic flow. As

with the United States research networks, estimates of traffic loads

or of peak hour traffic were not available for the international

networks or for the internationallinks.

To identify the current United States-international links three

activities were conducted. First, managers of the United States

Page 1-6
networks described in the previous study were asked to identify all

of their links with research networks outside the United States.

Next, information on the selected international networks was reviewed

to identify links with the United States research networks. Lastly,

records of international links were obtained from members of the

Coordinating Committee For International Research (CCIRN) and members

of the FNC Engineering Planning Group (FEPG). These records served

as the basis for the specification of the international links. The

findings from the first two activities were used as supportive data.

The current link speeds of the international links were obtained

from the records on the international links. The current link speeds

of the selected international networks were obtained from the

international network descriptions developed in this study.

The future links speeds of the international networks and of the

international links were based on the future plans for these networks

and these links. The future plans for the networks and the links

came from four groups of information: CCIRN drafted policy, FEPG

proposed policy, CCIRN perspective on worldwide research network

requirements, and major factors affecting international network

requirements.

The estimates of research network traffic flows developed in

this task were presented under two major topics: the current

international research network traffic flow, and the future

international research network traffic flow. Estimates of future

traffic flow were made for the same benchmark years (i.e., 1991,

1996, 2000, & 2010) used in the previous domestic research network

study These estimates were used in subsequent tasks to describe

new current and future integrated research networks (IRNs).

1.2.3.4 Identifying And Describing Recent Unexpected Changes In U.S.

Research Networks.

The purpose of this task was to describe any unanticipated

Page 1-7
changes in United States networks that have taken place, since the

completion of the previous study on domestic network requirements,

and that might have significant impacts on the current and future

Integrated Research Networks (IRNs) defined in this previous study.

That is, the intent of this task was to update the information

collected, during the previous study, on the United States research

networks and on the National Research and Education Network (NREN).

The focus was on changes related to the topologies of the United

Statesnetworks and to the plans for the NREN.

Updating the information on the United States research networks

and the NREN included the following activities: collecting

information from the managers of each network; collecting information

on the NREN from industry leaders; and organizing this information so

its impact on the current and future IRNs could be determined.

To collect information on the United States networks, the

managers of all the United States networks were contacted by mail and

by telephone. Each manager was sent a copy of the narrative

description and the topology map prepared during the previous study

for his network. He was asked to review this information and to

identify any major changes that should bc made in either the

narrative description or the topology map. This mailing was followed

up by telephone calls until the necessary information was obtained.

The information then was organized so that the impact of the

significant changes could be assessed.

Current information on the NREN plans was obtained by

interviewing industry leaders identified in the previous study and by

reviewing documents describing current NREN plans. Interviews were

conducted in person (e.g.,during the EDUCOM National Net'90) and

over the telephone. Documents were obtained from the various groups

and committees which arc involved in the planning of the NREN. Based

on the obtained information, the current status and future plans for

the NREN wcrc summarized and used in subsequent tasks when describing

the new current and future IRNs.

Page l-g
1.2.3.5 Describing New Current And Future Integrated Research

Networks (IRNs).

The purpose of this task was to describe, given the findings of

the current study, the new current and future Integrated Research

Networks (IRNs). That is, the intent was to use the results of Tasks

1-4 to modify the original IRNs developed in the previous study. It

was anticipated that the findings from Tasks 1 and 2, which include

descriptions of the international research network community and of

the major research networks outside of the United States, would

provide a worldwide perspective for developing the new IRNs. Then,

it was expected that the estimates of the current and future

international traffic flows developed in Task 3 and the update of the

United States Research networks and the NREN plans prepared in Task

4, along with the current and future IRNs described in the previous

study, would be used to develop new current and future IRNs.

To accomplish the aforementioned purpose, the completion of three

major activities was required: the assessment of the impact, on the

current and future IRNs, of unexpected changes in the United States

research networks and in the NREN plans; incorporation of the current

international research network traffic flow in the description of the

current IRN; and the incorporation of the future international

research network traffic flows in the description of the future IRNs.

To determine the impact of the unanticipated changes in United

States research networks on the current and future IRNs, each change

was reviewed to determine whether or not it would have an impact on

the original topology maps developed for the current and future

IRNs. That is, if the change required a modification of the major

access points, the connectivity, or the link speeds of any of the IRN

topology maps, these modifications were made.

In a similar manner, the current NREN plans were reviewed to

determine if any unanticipated changes in these plans required

Page 1-9
modifications in the original projections of future research network

requirements. Since this study does not focus on the political and

social implications of the NREN, but on its technical network

requirements, changes in the planned NREN technical network

requirements were given the most attention.

To incorporate the estimates of the current international

research network traffic flow in the description of the current IRN,

the information depicted on the original current IRN topology map,

the current link speeds of the international research networks, and

the descriptions of the current United States-international links

were summarized and presented in a single diagram. This analysis did

not result in the consolidation of United States-international links,

as was the case in the analysis of information on the future IRNs.

The single diagram that was prepared depicts the new current IRN; it

is the new current IRN topology map.

In a similar manner, the estimates of the future international

research network traffic flow were incorporated in the description of

the future IRNs. That is, the information depicted on the original

future IRN topology maps, the future link speeds of the international

research networks, and the descriptions of the future United Statesinternational links were summarized and presented in a single diagram

for each future benchmark year. As noted in the discussion of Task

3, the same future benchmark years (i.e., 1991, 1996, 2000 & 2010)

used in the previous domestic study were used again for this study.

Also, as noted in the discussion of Task 3, the United Statesinternational links initially were consolidated for 1991 and beyond

to give each United States city a maximum of one link to any foreign

country. When developing the new future IRNs, an additional

consolidation of links was made based on an understanding of network

requirements between the United States and each foreign country.

When making this additional consolidation, it was assumed that

continent-wide networks would be developing in selected parts of the

world (e.g., Europe), and that the United States would have several

Page 1-10
links to these continent-wide networks and would not need direct

access to every major country. This resulted in a maximum of one

United States-international link to each foreign country and only

indirect links to some countries.

While it is possible that the United States may desire more than

one link to some foreign countries or may desire separate links for

special projects, these desires were not reflected in the new future

IRN topologies, because these desires would be based more on needs

related to security and redundancy than on actual traffic flow.

Four new future topology maps were developed to depict the

results of these analyses of the future IRNs. These new. IRNs, while

still focused on the United States, now include international as well

as domestic research network requirements.

1.3 MAJOR FINDINGS

1.3.1 Overview

The major findings of this study are summarized below and focus

Off"

1. The description of the international research network community.

2. The description of the selected international research networks.

3. The current and future international research network traffic

flow.

4. The update of the United States research networks.

5. The new current and future IRNs.

1.3.2 The International Research Network Community.

The international research network community was described in

terms of its history, major international organizations, the major

international networks, and the United States' terrestrial and

satellite international gateways.

Page 1-I 1
The history of the international research network community is

similar, in many ways, to the history of research networks in the

United States. At the country level, some nations have sponsored

experimental networks like the ARPANET in the United States, most

nations have had to work to sell the value of research networks, and

all are facing similar policy and technological issues. At both the

country and the international levels, a variety of networks have been

developed, inter-network links have been established as the need

arose, and the needs to consolidate and coordinate efforts have

resulted.

A number of organizations have been formed to recommend and to

implement guidelines for planning, coordinating, and standardizing

international networking activities. Some important organizations

are: Coordinating Committee For Intercontinental Research Networking

(CCIRN), International Standards Organization (ISO), Consultative

Committee for International Telephoney and Telegraphy (CCITT),

Internet Activities Board (IAB), Federal Networking Council

Engineering Planning Group (FEPG), International Collaboration Board

(ICB) and the Reseaux Associes pour la Recherche Europeenne (RARE).

The general purposes of all of these organizations are to improve

services, increase connectivity, and reduce costs related to

developing and maintaining research networks throughout the world.

In the description of the international research network

community, networks were identified for the following areas:

Worldwide, North America, Europe, Asia, Australia/Pacific, Central

and South America and Africa. There are a wide variety of research

networks throughout these areas. Also, the various nations are at

different stages in the development of such networks. A few already

havc nationwide rcsearch networks, while many arc just beginning to

devclop their first research network. Also, a good number of

countries have little or no networking activity. Over 80 potentially

significant research networks were identified throughout the world.

About three-fourths of these are national networks, and about

one-fourth arc multi-nation, continent-widc or worldwide networks

Page 1-12
The most advance networks, as expected, are in the more advanced

industrialized countries, e.g., Canada, France, Germany, Japan and

the United Kingdom. Asia, Central and South America and Africa are

far behind in network development, but interest is growing in these

areas.

The United States terrestrial and satellite international

gateways include some twelve cable systems and 118 earth stations.

1.3.3 The description of the selected international research

networks.

Some eighty-four international research networks, which were

selected and described, are briefly described in Exhibits 1-2 and

1-3. The location, network name and link speeds for the eighty-four

networks are listed in Exhibit 1-2. These networks are summarized by

coverage, major geographical area and link speed in Exhibit !-3.

Coverage is defined in terms of four groups: worldwide,

continent-wide, multi-nation and single nation. About four-fifths of

the selected networks serve a single nation. The other one-fifth

serve either several nations, an entire continent, or most of the

world. The world-wide networks have the lowest maximum link speed,

while networks serving a single nation have the highest maximum link

speed. Across all groups, link speeds range from 1.2 to 1544 Kbps.

Seven major areas of the world were used to group these

networks. These areas are: Worldwide, North America, Europe, Asia,

Australia/Pacific, Central/South America, and Africa. About half of

the networks are in Europe, and the other half are distributed across

the other major areas. The networks with the highest maximum link

speeds are in Europe (Germany) and Asia (Japan). The networks with

the lowest maximum link speeds are in Central/South America and

Africa.

Networks were also grouped by maximum link speed.

groups of link speeds are: 1.2 Kbps to 19.2 Kbps; 48 Kbps to 768

Kbps; and 1544 gbps or more. About half of the networks fall into

the category with the lowest link speeds. Only about ten percent

have maximum links speeds of 1544 Kbps or higher.

1.3.4 The Current And Future International Research Network Traffic

Flow.

1.3.4.1 Current Traffic Flow

The current traffic flow was estimated by determining the

installed capacity of the international links between the United

States networks described in the previous study and the international

networks described in this study. That is, the current installed

capacity of the international links (see Exhibit 1-4 below), along

with the current link capacity of the selected international networks

(see Exhibit 1-3 above), was used to develop a picture of the current

international traffic flow.

There currently are 77 United States-international links that

connect 22 United States cities to 48 foreign cities in 18

countries. Over half of these links are to Europe, over half

originate from two United States cities (i.e., Greenbelt, MD and

Princeton, N J), and about half are NASA network links. The speeds of

these international links range from 9.6 Kbps to 1.544 Mbps. Over

half of the links are 19.2 Kbps or slower, and there currently is

only one 1.544 Mbps link.

1.3.4.2 Future Traffic Flow

To estimate the future international traffic flow, the future

link speeds of the international networks and the future link speeds

of the United States-international links were projected. These

projections were based on: CCIRN drafted policy, FEPG proposed

policy, CCIRN perspective on worldwide research network requirements,

and major factors affecting international network requirements

These policies, perspectives and factors were summarized in terms of

the following expectations:

I. International orRanizations like the CCIRN will encourage

worldwide network development and coordination.

2. World events are leading to an increase in multi-nation and even

global coot)erative research efforts which will require increased

connectivity.

3. Specific research in the areas of the environment, encr_v.

medicine and st)ace are demanding more advanced network functions

and new network applications.

4. Network technoloRv research and development will encourage and

facilitatenetwork development worldwide.

On the basis of these expectations, guidelines were developed for

projecting future link speeds for the international networks and for

the international links. The guidelines for projecting international

network link speeds were: all foreign countries would move toward

developing a nationwide research network; the link speeds of the

backbones of these networks would increase to speeds as high as 5

Gbps; only the backbone of these nationwide networks would be

projected; and networks that might be developed in the future would

bc considered when developing the new IRNs, but not when making these

projections. The guidelines for projecting the speeds of the United

States-international links were: these links would be consolidated

in 1991; the speeds of these links would increase to speeds as high

as 5 Gbps; only the consolidated links would be projected; new links

that might b¢ required in the future would be considered when

dcvcloping the new IRNs, but not when making these projections. In

both instances, projections would bc developed for 1991, 1996, 2000,

and 2010.

The projections of international network link speeds are listed

and summarized in Exhibits I-5 through 1-12. The following is a

summary of these projections:

I. 1991: about half of the international networks are expected to

have only a 9.6 Kbps backbone, about thirty-five percent arc

expected to have a 64 Kbps backbone, and only about fifteen

percent are projected to have a 1.544Mbps backbone.

2. 1996: about thirty percent of the international networks are

expected to have a 64 Kbps backbone, about thirty percent are

expected to have a 1.544 Mbps backbone, and about forty percent

are projected to have a 45 Mbps backbone.

3. 2000: about thirty percent of the international networks are

expected to have a 1.544 Mbps backbone, about thirty percent are

expected to have a 45 Mbps backbone, and about forty percent are

projected to have a l Gbps backbone.

4. 2010: about thirty percent the international networks are

expected to have a 45 Mbps backbone, about thirty percent are

expected to have a l Gbps backbone, and about forty percent arc

projected to have a 5 Gbps backbone.

To develop the projections of the United States-international

links, the current 77 links were consolidated. This process reduced

the number of international links, and therefore number of United

States cities and foreign cities directly linked. The only constant

was the number of foreign countries. The number of international

links was reduced from 77 to 20. The number of United States cities

was reduced from 22 to seven. The number of foreign cities was

reduced from 48 to 20.

In addition to the guidelines noted above, the projections of

the speeds of the international links were based, each year, on the

following: the number and speeds of links to each foreign country

during the previous benchmark year; the projected link speed of the

backbone of the network in each foreign country during the same

benchmark year; and the policies proposed by various organizations

concerned with international traffic.

The projections of the speeds of the United States-international

links are presented in Exhibit 1-13 through 1-16. The following is a

summary of these projections:

1. 1991: link speeds of the new 20 international links range from

1.3.5 The Update Of The United States Research Networks.

The update of the United States research networks was described

in terms of changes in the United States research networks and

changes in NREN plans.

There have been very few unexpected changes in the United States

Research Networks, since the completion of the previous study, that

must be considered when describing the new current and future IRNs.

The most important changes, those involving growth of the various

networks, were anticipated. Examples of unanticipated changes

included: one of the cities of a city pair was changed; a site was

dropped; and a network with slower link speeds increased its backbone

link speed from 56 Kbps to 1.544 Mbps several months earlier than

anticipated.

Since the completion of the previous study, NREN plans have

become more clearly delineated. The description of the NREN, in

terms of its goal, objectives, benefits, access, services, network

structure, management and funding, has been discussed and presented

many times. The NREN implementation plans are being implemented on

Page 1-40
schedule. Connectivity expectations have bccn well specified, the

NREN is in the second of three R&D stages, and the NREN testbed

program is equally well planned. Finally, a number of recent federal

agency, legislative and network development activities are directly

impacting the NREN and are helping to clarify major NREN issues

related to ubiquity, performance, funding and management.

In summary, there have been very few unexpected changes in the

United States Research Networks, since the completion of the previous

study, that must be considered when describing the new current and

future IRNs.

1.3.6 The New Current And Future IRNs.

To describe the new current and future IRNs, the results of

Tasks 1-4 were used to modify the original IRNs developed in the

previous study. First, the impact, on the current and future IR, Ns,

of unexpected changes in the United States research networks and in

the NREN plans was assessed and summarized. Then, the current

international research network traffic flow was incorporated in the

description of the new current IRN. Lastly, and in a similar manner,

the future international research network traffic flow was

incorporated in the descriptions of the new future IRNs.

The update of the United States research networks and the NREN

plans suggested that the original topology maps, developed in the

previous study for the current and future IRNs, appropriately reflect

expected domestic research network requirements. Therefore, it was

concluded that these original topology maps could be used as they

were presented in the previous study, along with information on the

networks outside of the United States and on the United Statesinternational links, to develop the new current and future IRNs.

Hence, it followed that changes would be made in these original

topology maps only if the information on the international networks

and the United States-international links indicate changes were

necessary.

Page 1-41
The incorporation of the current international research network

traffic flow in the description of the new current 1RN, resulted in

no change in the original current IRN domestic topology map, but

suggested a need to consolidate and improve the performance of United

States-international links (see Exhibit 1-17). Currently, there are

some 77 links connecting the United States research networks to

research networks in countries around the world. These links range

from 9.6 Kbps to 1.544 Mbps, and they connect a TI backbone in the

United States to research networks taround the world that have link

speeds ranging from 1.2 Kbps to 64 Kbps. Currently, there are no

direct United States links to Africa.

Thus, the current integrated domestic United States research

network has a backbone link speed that is higher than the backbone

link speed of the various networks in other parts of the world.

Also, it is higher than the typical link speed of links connecting

the United States to other parts of the world. Therefore, it was

concluded that the original current IRN topology map did not have to

be altered to incorporate current international network requirements. Because there are a large number of international links, it

was suggested that consolidating the international links would save

money just as integrating the networks in the United States would

save money.

In summary, the new current IRN topology map includes the

following: the original current domcstic topology map developed in

thc previous study; the 77 international links to six major areas of

the world; and the range of the typical link speeds of the backbones

of the research networks in the countries in the six major arcas.

The incorporation of the future international research network

traffic flows in the descriptions of "the new future IRNs, resulted in

no changes in the original future IRN domestic topology maps, but, as

for the new current IRN, suggested a need to consolidate and improve

the performance of United States-international links for each

benchmark year.

A Consolidation of the United States-international links in 1991

resulted in only 10 links connecting the United States research

networks to research networks in countries around the world (see

Exhibit 1-18). In 1991, these links are all projected to be 1.544

Mbps links except for the two links to Mexico and Central/South

America which are expected to be 128 Kbps links and one of the two

links to Asia which is expected to be a 9.6 link. The ten links

connect a T3/TI backbone in the United States to research networks

around the world that have link speeds ranging from 9.6 Kbps to 1.544

Mbps.

Thus, the 1991 United States research network has a backbone

link speed that is still higher than the backbone link speed of the

various networks in other parts of the world. Also, it is higher

than the typical link speed of projected links for connecting the

United States to other parts of the world. It was therefore concluded

that the original 1991 topology map does not have to be altered to

incorporate international research network requirements. However, it

was also suggested that continual improvements arc needed in the

United States-international links to make certain the United States

research networks have adequate connectivity with research networks

around the world. These improvements were indicated by the increase,

noted above, in the speeds of the United States-international links.

In summary, the new 1991 IRN topology map includes the

following: the original 1991 domestic topology map developed in the

previous study; the 10 1991 consolidated international links to six

major areas of the world; and the range of the typical 1991 link

speeds of the backbones of the research networks in the countries in

the six major areas.

In 1996, only 10 links arc projcctcd (thc samc as projcctcd for

1991) for connecting the United States rcscarch networks to research

networks in countries around the world (see Exhibit 1-19). Thcsc

links in 1996 are all projected to be 45 Mbps links except for two

links to Mexico and Central/South America and one to Asia which are

each expected to be 1.544 Mbps links. The ten links connect a

backbone, ranging in link speeds from 45 Mbps to I Gbps, in the

United States to research networks around the world that have link

speeds ranging from 9.6 Kbps to 45 Mbps.

Thus, the 1996 United States research network has a backbone

link speed that is still higher than the backbone link speed of the

various networks in other parts of the world. Also, it is higher

than the typical link speed of links connecting the United States to

other parts of the world. Therefore, as before for 1991, it was

concluded that the original 1996 topology map does not have to be

altered to incorporate international research network requirements.

Again, however, it was also suggested that continual improvements are

needed in the United States-international links to make certain the

United States research networks have adequate connectivity with

research networks around the world. And again, these improvements

were indicated by the increase, noted above, in the speeds of the

United States-international links.

In summary, the new 1996 IRN topology map includes the

following: the original 1996 domestic topology map developed in the

previous study; the 10 1996 consolidated international links to six

major areas of the world; and the range of the typical 1996 link

speeds of the backbones of the research networks in the countries in

the six major areas.

In the year 2000, the same 10 links are projected for connecting

the United States research networks to research networks in countries

around the world (see Exhibit 1-20). However, these links in year

2000 are all projected to be 1 Gbps links except for two links to

Mexico and Central/South America and one to Asia which are each

expected to be 45 Mbps links. The ten links connect a backbone,

ranging in link speeds from 272 Mbps to 5 Gbps, in the United States

to research networks around the world that have link speeds ranging

from 9.6 Kbps to 1 Gbps.

Thus, the 2000 United States research network has a backbone

link speed that is still higher than the backbone link speed of the

various networks in other parts of the world. Also, it is higher

than the typical link speed of links connecting the United States to

other parts of the world. Therefore, as before for 1996, it was

concluded that the original year 2000 topology map does not have to

be altered to incorporate international research network

requirements. Again, it was also suggested that continual

improvements are needed in the United States-international links to

make certain the United States research networks have adequate

connectivity with research networks around the world. And again,

these improvements were indicated by the increase, noted above, in

the speeds of the United States-international links.

In summary, the new year 2000 IRN topology map includes the

following: the original year 2000 domestic topology map developed in

the previous study; the 10 consolidated international links to six

major areas of the world; and the range of the typical year 2000 link

speeds of the backbones of the research networks in the countries in

the six major areas.

In year 2010, the same 10 links are projected for connecting the

United States research networks to research networks in countries

around the world (see Exhibit 1-21). As before, these links are

expected to be operating at higher speeds. In year 2010 they are all

projected to be 5 Gbps links except for two links to Mexico and

Central/South America and one to Asia which are each expected to be 1

Gbps links. The ten links connect, in year 2010, a backbone, ranging

in link speeds from 1 Gbps to 25 Gbps, in the United States to

research networks around the world that have link speeds ranging from

64 Kbps to 5 Gbps.

Hence, the year 2010 United _ States research network has a

backbone link speed that is still higher than the backbone link speed

of the various networks in other parts of the world. Also, it is

higher than the typical link speed of links connecting the United

States to other parts of the world. Therefore, as before for year

1.4 RECOMMENDATIONS

A consensus of academic, industry, and institutional experts

engaged in developing and operating computer research networks is

that significantly higher communications capacities will be needed in

the years to come to link researchers around the world to enable them

to collaborate in cooperative research endeavors regardless of their

physical locations. The researchers' needs for communications will

encompass accessing large data bases, linking supercomputers in a

massively paralleled configuration, and presenting simulation results

with ever-increasing resolution and clarity to permit researcher to

overcome resource limitations.

NASA needs to address several technology and policy issues in

order to translate today's vision into what some experts have called

the "Collaboratory" of the future. Some specific recommendations are

as follows:

1. Support the development of the NREN which will improve network

performance and ubiquity for researchers and educatiors.

Page 1-51
2. Support the consolidation of U.S,-international links, thereby

increasing network performance and ubiquity worldwide.

3. Support the development of a worldwide research and education

network (WREN), thereby improving research and education

worldwide.

4. Support the further study of both policy and technical issues

related to the implementing of the computer research

initiatives already put forth by the White House and Congress.

5. Continue to examine its own computer research network

requirements and to work to incorporate these needs in the

development of the NREN.

SECTION 2

THE INTERNATIONAL RESEARCH

NETWORK COMMUNITY

2.1 OVERVIEW

2.1.1 Purpose

In this section the international research network community is

described. This description was developed so that the major research

networks, which are outside the United States and with which the

United States research networks have or may have requirements to

interface, could be selected. Included in this deseiption of the

international research network community are three major summaries or

outlines: a summary of the history of the development of the

international research networks; a summary of the major organizations

involved in the development and coordination of these networks; an

outline of all the significant research networks outside the United

States, and a summary of the gateways in the United States.

2.1.2 Approach

The development of the description of the international research

network community began with an initial review of the literature on

international research networks. Selected books, articles and

reports were reviewed to obtain information on the history,

development and operation of such networks. This initial review

helped structure interviews with leaders in the development of United

States research networks. From the initial review and the

interviews, preliminary information on international networks was

developed, and contacts were identified. These new contacts were

telephoned, and additional information on international research

networks was obtained.

Page 2-1
This information was aggregated and analyzed, and provides the

basis for describing the international research network community.

2.2 HISTORY OF INTERNATIONAL RESEARCH NETWORK COMMUNITY

The history of the development of research networks outside the

United States is summarized in this section. First, the similarity

of the development of research networks in the United States with

that in other countries is noted. Next, the similarity of the United

States development with that taking place on a multi-nation or

worldwide basis is discussed. Then, an overview of the early network

development in countries, which today are leaders in research

networking, is presented.

2.2.1 Network Development: United States & Other Countries

Many of the events that occurred in the development of research

networks in the United States, have occurred or are occurring in the

development of research networks outside the United States. In some

countries, the events occurred in the same time frame as in the

United States, in other cases, the events just now are taking place.

For example, some countries have sponsored experimental

networks, like ARPANET, whose initial purpose was to develop

networking technology, but whose development and use led to the

development of much larger general purpose research networks. In

some cases, this sponsorship occurred about the same time as the

ARPANET sponsorship in the United States, while in other countries

such sponsorship is still in the planning stages.

Another example of the similarity in the development of research

networks in the United States and in other countries pertains to the

initial selling of the value of such networks. All countries have

worked to convince, or are in the process of trying to convince,

potential sponsors and users of the immediate and long-range value of

Page 2-2
developing research networks.

Also, in some countries the proliferation of small networks

followed by the need to consolidate networks has mirrored events in

the United States. Once interest and need were obvious, networks

developed to meet researchers' needs in a geographically limited area

merged with and overlapped other networks. These events, as in the

United States, were stimulated by major technological advances and

funding concerns, all of which lead to the need to consolidate

research networks for reasons related to efficiency and

effectiveness.

The same policy and technological issues faced in the United

States also have been, or are being, faced in other countries. As

examples, issues related to access, coordination, funding, and

standards have been problems for users and managers in other

countries just as they have been in the United States. While the

issues often have been similar, the responses and approaches to

resolving the issues have varied by country. The differences in

approaches have resulted partly because of cultural differences and

partly because the approaches were implemented at different times;

that is, approaches often reflected available technological

capabilities and understanding.

2.2.2 Network Development: United States & Worldwide Efforts

The development process that was begun at the country level

(e.g., as in the United States or the United Kingdom), is now being

repeated at the continent level (e.g., Europe) and the worldwide

level. The following discussion includes an example of the

similarities of the United States network development process with

those of continent-wide or worldwide efforts.

In the United States, for example, networks have expanded and

links to other networks have been established as the needs arose.

Likewise, networks within a continent, for example Europe, and on

Page 2-3
different continents (e.g., the United States and Europe) have

established interconnectivity as the needs arose. In both cases,

what has resulted frequently is a multiplicity of low speed links,

which are too expensive. Again, in both cases, the corrective action

taken often has been to work towards consolidation.

These actions have led or are leading to nationwide, continentwide and worldwide networks. Of particular interest for this study,

is the similarity between the development of a nationwide backbone to

link regional networks in a nation and the development, currently

being discussed, of a worldwide backbone to connect nationwide

networks. The intent in both cases is to improve services and reduce

costs. In the later case, a nation's national research network,

e.g., the NREN in the United States, would become a "regional"

network in a worldwide network.

2.2.3 Examples Of Early Network Development

The network development in five countries (excluding the United

States) which are leaders in research network development is

discussed in this section. These countries are: the United Kingdom,

France, Germany, Canada and Japan. Just as the ARPANET has been the

forerunner of research networks in the United States, similar

experimental research networks have been the forerunners of research

networks in the first four countries listed above, and have led to

the planning and development of national research networks. In the

case of Japan, its current nationwide research network has the dual

purposes of networking research and support for other research, but

its earlier networks were designed only for other research.

2.2.3.1 The United Kingdom

The United Kingdom conducted some of the early work in

experimental networks and now has a nationwide research network. One

of the earliest packet switching networks was implemented at the

National Physical Laboratory (NPL) in the United Kingdom in 1968,

Page 2-4
when the ARPANET was built. An international connection was

established to CYCLADES in 1974 (See discussion below, on France, for

description of CYCLADES).

Initial planning for the Science and Engineering Research

Council Network (SERCnet), the country's first major network for

supporting other research, actually began back in 1966. This network

progressed through several developmental phases with several names

during the late 1960's and early 1970's and was established as a

research network, named SERCnet, in 1977. SERCnet, jast as NSFNET in

the United States, was designed to connect regional computer centers.

A national research network, JANET (for Joint Academic Network),

was formed in 1982, and SERCnet was integrated into JANET in 1984.

Networks of other major national organizations (e.g., the Natural

Environment Research Council) also merged with JANET. Because there

was a single ultimate source of funding (i.e., the Department of

Education and Science) for all of these early networks, the merging

of all the networksdid not present much of a problem. This

consolidation has led to increased connectivity, new services and

reduced overall costs.

2.2.3.2 France

In France, the CYCLADES network, implemented in the early 1970s,

was designed to serve as a research network as well as a platform for

supporting other research. CYCLADES, similar in many ways to the

earlier ARPANET in the United States, was coordinated by what is now

called the National Research Institute for Computer Science and

Automation. The network became operational in 1973, grew slowly

through the 1970's because of budget constraints, underwent

developmental changes, and established some international links.

CYCLADES was phased out in 1981. This network, did, however, have a

significant impact in France and internationally, on the development

of network technology (e.g., the ISO-OSI model).

Page 2-5
Two other French networks, developed relatively early, were RPC

for Reseau Communication par Paquet and COSAC for Communications Sans

Connections. RPC played a major role in the evolution of X.25, and

research was conducted on COSAC during the mid 1980s.

As with the United Kingdom, these early networks efforts have

led to the development of more advance research networks in France

like REUNIR which is an acronym for Reseau des Universities et de la

Recherche.

2.2.3.3 Germany (the Federal Republic of Germany)

Germany has contributed significantly to network development.

One of its earlier networks, the Hahn-Meitner Institut (H/VII) Network

(HMI-NET) was established in Berlin during the mid to late 1970's.

H/VII-NET, is similar to CYCLADES and ARPANET in that it has been an

experimental network and has contributed to the development of a

community of network experts. H/vII-NET also has contributed directly

to the development of Germany's research networks, BERNET (a regional

research network) and DFN (Deutsches Forchungsnetz), Germany's

national research network. In fact, one of the early developers of

HMI-NET has recently proposed a continent-wide fiber optic network

with speeds of 100 Mbps and more.

2.2.3.4 Canada

One of Canada's earliest networks, the Defense Research

Establishment Network (DREnet), also began as an ARPANET-like

network. DREnet was begun in 1983 to link Defense Research

Establishments in Ottawa, Ontario and Nova Scotia. Like the ARPANET,

the DREnet is scheduled to be replaced by a more advanced network,

the XDRENET.

As in the United States, other networks, like CDNnet and

NetNorth, were designed to support a variety of research, education

and development activities. Currently, the Canadian National

Page 2-6
Research Council is developing a national research network, similar

to the NSFNET (like NSFNET, it will have three levels: a backbone,

mid-level regionals and campus networks), that will integrate all

networks that support research activities. The network is called

CA'net (for Canadian Network).

2.2.3.5 Japan

There was not much networking activity in Japan until the

privatization of Nippon Telegraph and Telephone (NIT) and the

corresponding deregulation of the public telephone system in 1985.

Since then, networking activity in Japan has increased

significantly. Today, there are a wide variety of networks in Japan,

and many of the international networks (e.g., BITNET, CSNET, UUNET,

HEPNET) reach Japan.

The oldest major network in Japan is N-I which was started in

1981 as an interuniversity network. The National Center for Science

Information Systems (NACSIS) Network, established in 1987, is the

likely successor to N-I. Today NACSIS connects Inter-University

Computing Centers throughout the main Japanese islands and gives

researchers access to a wide range of computing facilities including

supercomputers.

The major nationwide research network in Japan is JUNET which

was begun in 1984. This network's purpose is to promote information

exchange among Japanese researchers and with researchers outside

Japan. It also provides a test environment for research in

networking.

Also, the Japanese government is encouraging implementation of

campus networks and is funding two new high-speed international links

to the United States and Europe. These links are being developed in

cooperation with the United States National Science Foundation, and

are expected to be operational in the early 1990s.

2.3 MAJOR INTERNATIONAL ORGANIZATIONS

A number of internationl groups have been organized to recommed

guidelines for planning, coordinating, and standardizing

international networking activities. A brief discussion of a sample

of such groups will help provide a perspective on some of the forces

that will directly impact the international network research

community.

2.3.1 Coordinating Committee For Intercontinental Research Networking

One of the most important organizations that provides guidance

for international research network activity is the Coordinating

Committee For Intercontinental Research Networking (CCIRN). The

CCIRN, which was initially known as the Necessary Ad Hoc Coordinating

Committee (NACC), was established in 1987 and held its first meeting

in the Spring of 1988.

The purpose of the CCIRN is to facilitate the development of

interoperable networking services between pariticipating entities to

support open research and scholarly pursuit. It discusses policy,

management and technical issuesand aims to:

I. Stimulate cooperative intercontinental research by promoting

enhanced interoperablcnetworking services.

2. Optimize use of resources and coordinate international

connections of the networks represented on the CCIRN.

3. Promote the evolution of an open internationalresearch network.

4. Coordinate development of international network management

techniques.

5. Exchange resultsof networking research and development.

The CCIRN members represent organizations with an active

interest in developing a worldwide network with the aims noted

above. Initially, members were from the United States and Europe.

Membership now includes Canada, and invitations have bcen given to

other nations, like Australia and Japan. It is hoped that all

Page 2-8
nations interested in the aims noted above will eventually join.

Examples of the types of organizations represented on the CCIRN are

the following: United States---Federal Networking Council (FNC)

which has replaced the Federal Research Internet Coordinating

Committee (FRICC), Internet Activity Board and CSNET/BITNET;

Europe--=the Reseaux Associes pour la Recherche Europeenne (RARE),

(see description below); Canada--- National Research Council. The

CCIRN has two chairs: the chair of the FNC and the secretary General

of RARE.

There are a number of groups that have been formed at the

continent and nation level and that provide representation on the

CCIRN. There is a North American CCIRN (NACCIRN) which includes the

United States and Canada. Other nations are being asked to join

NACCIRN. In the United States, the NACCIRN provides representation

on the CCIRN. In Canada, a Canadian Coordinating Committee on

Research Networking (CCCRN) has been established, includes

represntatives of the national networks, and provides representation

on the CCIRN and the NACCIRN. There also is a EUROCCIRN which

corrdinates European networking needs and provides representation on

the CCIRN.

2.3.2 Other Worldwide Organizations

Three other important worldwide bodies are the International

Standards Organization (ISO), the International Electrotechnical

Commission (IEC), and the International Consultative Committee for

Telephony and Telegraphy (CCITT).

The ISO is the main international organization that handles

networking issues and is composed of national standards bodies of 89

member countries. The IEC is composed of technical experts and

pursues activities complimentary to those of the ISO. The IEC

handles electrical and electronic standards and the ISO handles

everything else.

The United Nations has several agencies that affect networking

standards. The most notable is the CCITT. The CCITT is closely

Page 2-9
associated with the national telephone companies and develops

specifications of networking protocols and related standards.

2.3.3 United States Organizations

There are several groups in the United States which are working

on coordinating United States/International connections. These

include the United States Internet Activities Board (IAB) and the FNC

Engineering Planning Group (FEPG).

The IAB, recently reorganized, is responsible for Internet

policy, standards, liaison, and facilities. The Internet Engineering

Task Force (IETF) reports to the IAB and is responsible for host

based services, Internet based services, network management, OSI

interoperability, routing and user services. The Internet Research

Task Force (IRTF) also reports to the IAB and is responsible for

coordinating various network research activities. The IAB has

liaison activities with, e.g., the FNC, the CCIRN, and RARE

(discussed below).

The FNC Engineering Planning Group (FEPG) was set up to assist

the FNC in translating its policy goals into implementable technical

programs. It currently is developing a policy for United States

international connections.

2.3.4 European Organizations

Three major European organizations concerned with international

connectivity are the European Conference of Postal and

Telecommunications Administrations, the CEPT, the International

Collaboration Board (ICB), and the Reseaux Associes pour la Recherche

Europeenne (RARE).

The CEPT is the European equivalent of the CCITT. Many of the

individuals who belong to the CCIRN also belong to the ICB. The ICB

is a European group that has been concerned primarily with the

planning of a worldwide backbone.

Page 2-10
RARE, is an association of European research network managers

and users. Its purpose is to promote network services, with a

special emphasis on international connectivity, for the research

community in European countries. RARE is a membership organization

funded by dues from its national members. There are a number of

memberships types. For example, full national members are national

academic and research network organizations (one per country).

Recently, talks were held between RARE and managers of the

existing European continental networks EARN, EUnet, and HEPnet about

the use of a common infrastructure. The networks and RARE agreed in

principle, but there was some disagreement with the PTTs about

charging. Also, these networks do not use the ISO-OSI protocols and

make significant use of leased lines rather than the PTT Public Data

Networks (PDNs). Consequently, it is uncertain whether these

networks will be replaced by a new ISO-OSI network or be converted to

become a part of it. Also, RARE considers interconnection with the

United States a problem, because NSFNET uses TCP/IP protocol, and

RARE considers TCP/IP to be a short-term solution to protocols for

high-speed networks.

2.3.5 Other Nations - Japan As An Example

Most other nations involved in developing research networks also

have coordinating and planning bodies. While these vary from country

to country, a brief discussion of one country will help provide a

perspective on other such national coordinating bodies.

In Japan, the Ministry of Posts and Telecommunications (MPT)

oversees all telecommunications policy in Japan and performs many of

the functions performed by the FRICC and the FCC in the United

States. Also in Japan, the Interoperability Technology Association

for Information Processing (INTAP) is a nonprofit research and

development group established by the Ministry of International Trade

and Industry to promote the development of interoperability

technology for information processing. For example, the INTAP is

interested in implementing ISO-OSI protocols and standards.

2.4 OVERVIEW OF RESEARCH NETWORKS

As noted, in the discussion of the history of international

research networks outside of the United States, there are a wide

variety of research networks throughout the world. Also, the various

nations are at different stages in the development of such networks.

A few already have nationwide research networks, while many are just

beginning to develop their first research network. In this section,

the status of research networks and a list of current research

networks are presented. For this purpose, networks are categorized

into seven categories depending upon the geographical extent of the

network (See Exhibit 2-1).

The nations in each category are listed, if they have a research

network that is more than a host on one of the worldwide or

continent-wide networks. If a nation is not listed below, it is

noted in the discussion of status of research networks in the area.

The category, "North America" does not include the United States; the

research networks in the United States were documented in a previous

study (U.S. Research Networks, Current & Future. NASA Study Contract

NAS3-25083, Task Order 2, December, 1989). This previous study will

be referred to, throughout this report, and, when it is referred to,

it will be called the U.S. Domestic Research Network Study.

The international research networks (i.e., the research networks

not in the United States) are listed below. This list was used to

identify the significant research networks that are described in

Section 3.

2.4.1 Worldwide Networks

There are a number of networks whose funding and administration

is decentralized, whose connections are worldwide, and whose purpose

includes facilitating research. These networks are:

BCnet (British Columbia Network)

CDNnet (Canada Network)

CRIM (Computer Research Institute of Montreal) Network

DREnet (Defense Research Establishment Network)

NetNorth

CA'net (Canadian Research Network)

2.4.2.2 Mexico

Mexico has been developing two major networks and is planning to

join the NACCIRN. These two networks are:

ITESM (Instituto de Estudioe Superiores de Monterrey) Network

UNAM Network (National University of Mexico Network)

2.4.3 Europe

There are several widely used networks or associations that have

served the continent of Europe. Five examples are listed below under

continent-wide networks. Another network, the European Informatics

Network (EIN) was a mid-1970s attempt to provide a continental

research network in Europe; it no longer exists. There also are

examples of networks that serve several nations.

Page 2-14
/vlany nations in Europe do not have their own research networks.

Iceland, Luxemberg and Portugal only have hosts on EUnet, and Turkey

only has a host on EARN. There have been very few network

connections to the Soviet Union or the Eastern European countries.

Also, these countries, except for the Soviet Union, don't tend to

have their own networks. Bulgaria, Czechoslovakia, the Democratic

Republic of Germany, Hungary and Poland all have connections to the

multi-nation network, IASnet. There are no known systems in Albania

or Romania. The following is a list of the research networks in

Europe.

India, Indonesia, Israel, Malaysia and Thailand. The other countries

either have only connections to worldwide or multi-nation networks or

no system at all.

The People's Republic of China has several connections to the

rest of the world: a CSNET link to West Germany; a UUCP link to

HARNET in Hong Kong; a 1200 bps link to Vienna, Austria. Singapore

got the first BITNET node in Southeast Asia. Taiwan, the Republic of

China, has connections to both BITNET and PACNET. There appears to

be AUSEAnet connections in the Philippines and in Sri Lanka. Cyprus

is an EARN member. Mongolia has a connection to IASnet. There are

PDNs in Bahrain, Iraq, Qatar, Saudi Arabia and United Arab Emirates.

There are CGNET (see Africa below) subscribers in Bandladesh, Nepal

and Sri Lanka.

The situation in Central and South America is similar to that in

Asia (especially Southeast Asia). There is a growing interest in

networking, but there are few operating networks. In this area,

there are two multi-nation networks, and links to other networks.

Puerto Rico has an active local branch of FidoNet called RED.

The Center for Population and Family Health (at Columbia University)

uses a Kermit connection to reach Haiti. There is a connection to

IASnet in Cuba. There is a BITNET node in both Argentina and Chile.

Brazil is planning to create an academic network to connect research

centers in universities and industry and government laboratories.

network.

Ethiopia, the Ivory Coast, Mali, and Niger each have connections

to CGNET. Algeria, the Ivory Coast, and Morocco each has an EARN

connection. Senegal has a packet radio network. Kenya is setting up

a PeaceNet type network. South Africa apparently has internal

networks, but external connections are few, as requests to connect to

major worldwide networks (e.g., EARN and BITNET) have been turned

down. There are no known networks in Cameroon, Libya or Nigeria.

2.5.2 Satellite Gateways

There are an estimated 118 United States international earth

stations. About 50 percent of these are located on the East Coast,

Page 2-21
about 30 percent on the West Coast, and the remainder throughout the

United States. The purposes of these earth stations include:

general purpose international, international business service,

international data records, and non-standard general purpose. The

uplink and downlink frequencies of these earth stations are 6/4 GHz

and 14/11 GHz.

2.6 SUMMARY

The history of the international research network community is

similar, in many ways, to the history of research networks in the

United States. At the country level, some nations have sponsored

experimental networks like the ARPANET in the United States, most

nations have had to work to sell the value of research networks, and

all are facing similar policy and technological issues. At both the

country and the international level, a variety of networks have been

developed, inter-network links have been established as the need

arose, and the need to consolidate and coordinate efforts has

resulted.

A number of organizations have been formed to recommend and to

implement guidelines for planning, coordinating, and standardizing

international networking activities. The most important

organizations are: CCIRN, ISO, CCITT, IAB, FRICC FEPG, ICB and

RARE. The general purposes of all of these organizations are to

improve services, increase connectivity, and reduce costs related to

developing and maintaining research networks throughout the world.

In this description of the international research network

community, networks were identified for the following areas:

Worldwide, North America, Europe, Asia, Australia/Pacific, Central

and South America and Africa. There are a wide variety of research

networks throughout these areas. Also, the various nations are at

different stages in the development of such networks. A few already

have nationwide research networks, while many are just beginning to

develop their first research network. Also, a good number of

Page 2-22

w

j
• countries have little or no networking activity.

About 80 potentially significant research networks were

identified throughout the world. About three-fourths of these are

national networks, and about one-fourth are multi-nation,

continent-wide or worldwide networks. The most advance networks, as

expected, are in the more advance industrialized countries, e.g.,

Canada, France, Germany, Japan and the United Kingdom. Asia, Central

and South America and Africa are far behind in network development,

but interest is growing in these areas.

The United States terrestrial and satellite international

gateways were summarized briefly to provide a perspective for

understanding subsequent discussions of United States-international

network links and international connectivity requirements. Some

twelve cable systems and 118 earth stations were noted.

This information on the international research network community

was used to select and describe research networks outside the United

States and to determine United States requirements for connectivity

with these networks. These descriptions and requirements are

presented in the following sections.

Page 2-23

SECTION 3

DESCRIPTION OF SELECTED INTERNATIONAL

RESEARCH NETWORKS

3.1 OVERVIEW

3.1.1 Purpose

In this Section, many of the international research networks,

identified in Section 2, are selected and described. The intent is

to present a picture of the level of research network development

around the world, so that the current and future levels of United

States/International research network traffic flow can be estimated.

The descriptions of the selected international research networks,

along with information from managers of United States research

networks and from other leaders in the field, will be used to

identify current United States/international links. The

identification of these links, along with current and future

estimates of the topologies of the international networks, in turn,

will be used to estimate current and future United Statesinternational traffic flow. This section includes a brief summary of

the approach used to select the international research networks and

the descriptions of the individual networks.

3.1.2 Approach

To accomplish the aforementioned purpose, the completion of two

major activities was required: selecting the networks and then

describing the networks. The selection process is explained in the

next sub-section. Once the international networks were selected,

describing them involved collecting additional information, drafting

summaries of network information, and reviewing and modifying the

summary descriptions. Information on the selected international

networks was collected through interviews and telephone calls with

research network leaders and managers.

Page 3-1
3.2 SELECTION OF INTERNATIONAL RESEARCH NETWORKS

3.2.1 Selection Criteria

Since the major intent was to present a picture of the level of

research network development around the world, a comprehensive

picture of a wide variety of network efforts had to be developed.

Therefore, the criteria used to select the international research

networks, had to result in the selection of networks that varied on

such elements as size (i.e., extent of coverage), link speed, and

connectivity. Consequently, a network was selected if information on

the network was available and if it met one or more of the following

criteria:

1. It is a major worldwide network.

2. It is a major multi-nation network.

3. It is the only multi-nation network serving a region of the

world.

4. It is a major national network.

5. It is the only national network for a country.

6. Within a nation, it is an advanced regional (in contrast to

nationwide) network.

7. Within a nation, or among nations, it is, or was, an important

experimental network.

8. It has an international link with the United States.

3.2.2 List Of Networks Selected

The application of the criteria listed above resulted in the

selection of most of the networks identified in Section 2. These

networks are listed in Exhibit 3.1. The selected networks represent

the following seven areas of the world: Worldwide, North America,

Europe, Asia, Australia/Pacific, Central and South America, and

Africa. A total of eighty-four international research networks are

described on the following pages. The descriptions are presented by

area of the world, starting with Worldwide networks. Information on

these eighty-four networks is summarized at the end of Section 3.

3.3.3 USENET

USENET, which means "User's Network," is one of the oldest and

largest networks. It began in 1979 and one of its goals has been to

give every UNIX-based system the opportunity to join and benefit from

a computer network. Today it has over a half million users in 17

countries on five continents (i.e., North and South America, Europe,

Asia, and Australia). Any one can join, and it is very

decentralized. The two most common protocols used are UUCP and News

Transfer Protocol (NTP). USENET has only one basic service, "news,"

and is sometimes called netnews. The news at each site is under the

control of the site administrator, but there are no strict rules

about user access to the USENET. There is no central funding source,

and each host pays for its own transmission costs. Most of its

backbone links run at about 11 Kbps.

3.3.4 UUCP NETWORK

UUCP (which is an acronym for UNIX to UNIX Copy Program) Network

is one of the oldest dial-up networks in the world. It began in

1978. It extends throughout the world and mostly connects machines

that run the UNIX operating system. There are probably more than a

million users on the network making it one of the largest. The UUCP

protocol is used, and mail is the only service provided throughout

the world. UUCP is very decentralized and has no central authority

that determines access. Its topology varies from almost random

connections in North America to near tree structure on other

continents. The speed of its links vary from 1200 bps to 11 Kbps,

with 2400 bps most common.

3.3.5 UUNET

UUNET is a subscription network service for users on UUCP and

USENET. UUNET offers access through X.25, dial-up and public data

networks. It provides quick transfer of mail and news among the

hosts on UUCP and USENET and provides a European connection (via

EUnet) to the Internet. UUNET is administered from Falls Church

Page 3-7
Virginia and is connected to NSFNET through SURAnet. There is an

international link to Amsterdam. Subscribers are charged hourly

connection charges and a flat monthly fee. Dial-up speeds range from

1200 bps to 11 Kbps. Plans for expanding this service are

underway.

3.3.6 FIDONET

FIDONET, named for a computer, began in 1983 and was designed to

connect IBM PCs or compatibles running MS-DOS. The network extends

throughout the world and is arranged in a tree structure, divided

into zones by continental areas. Most nodes are in the United States

and Europe. It uses the Fido protocol which is a dial-up protocol,

and its major services are mail and conferencing. FIDONET now has

over 6000 nodes throughout the world. The speed of most

long-distance links with high traffic volume is 9.6 Kbps; there are

many lower volume links with speeds at 1200 and 2400 bps. The

network is administered by the coordinators of the nodes at the

various levels of its routing hierarchy. The International FidoNet

Association also provides assistance.

3.4 NETWORKS IN NORTH AMERICA

Networks in North America, except in the United States, include

major research networks in Canada and Mexico.

3.4.1 Networks In Canada

Canada has a number of national and regional research networks. As

noted in Section 2, one of its earlier networks, DREnet, began as an

ARPANET-Iike network. Others, like CDNnet and NetNorth, were

designed to support a variety of research, education and development

activities. Currently, the Canadian National Research Council is

developing a national research network, similar to the NSFNET, that

will integrate these networks that support research activities. The

In the following descriptions of these networks link speeds are

noted. International link speeds often are indicated in terms

different from those used in the United States. For examples, in

Europe 11 Kbps is often used rather than 9.6 Kbps as in the United

States, and 2 Mbps is typically used rather than 1.544 Mbps. When

link speeds are indicated for each- of the international network

listed in this exhibit, the designation used in the particular

country is used. However, in future sections of this report where

forecasts of these international networks are developed and compared

with forecasts of U.S. domestic networks, a common designation (i.e.,

the U.S. designation) of link speeds is used.

3.3 WORLDWIDE NETWORKS

There are a number of networks whose funding and administration

is decentralized, whose connections are worldwide, and whose purpose

includes facilitating research. Examples of these networks are:

BITNET, CSNET, USENET, UUCP Network, UUNET and FIDONET.

3.3.1 BITNET

BITNET is a cooperative network which serves more than 2300

hosts at nearly 1000 sites in 32 countries. The main parts of the

network are:

1. BITNET in the United States, Mexico and Chile.

2. NetNorth in Canada.

3. EARN in Europe with hosts in 24 countries.

4. Asianet with hosts in Japan, Singapore, Taiwan and Korea.

The major services include electronic mail and file transfer. Its

link speed is typically 9.6 Kbps. BITNET, as indicated above, has

connections throughout the world, including direct links to Canada,

France, Germany, Japan, Malaysia, Saudi Arabia, Brazil, Chile,

Mexico, and Puerto Rico. It has recently merged in the United States

with CSNET.

3.3.2 CSNET

CSNET, whose purpose has been to facilitate research and

development in computer science and engineering, began in 1981. It

uses a variety of protocols, and electronic mail is the only service

supported on all parts of CSNET. While the network is mostly in the

United States and Canada, it has links to international members and

affiliates in Australia, Finland, France, Germany, Israel, Japan,

Korea, New Zealand, Sweden, Switzerland, the United Kingdom and the

People's Republic of China. Its link speed is typically 9.6 Kbps.

CSNET uses dial-up links and gateways to access other networks (e.g.,

NSFNET). As noted above, it has merged with BITNET.

Page 3-6
network is called CA'net.

CRIM, and Onet.

3.4.1.1 DREnet

Regional networks include: AHEN, BCnet,

The Defense Research Establishment Network (DREnet) is a group

of networks that link the sites and systems involved in research for

the Canadian Department of National Defense. DREnet began in 1983 as

an ARPANET like network linking Defense Research Establishments in

Ottawa, Ontario and Nova Scotia. There are nine DREnet sites, 11

networks and about 45 hosts. The DREnet is scheduled to be retired

and its sties will join the relatively new XDRENET. XDRENET uses

TCP/IP over an X.25 PDN, and will have link speeds up to 64 Kbps.

3.4.1.2 CDNnet

CDNnet (CDN is an abbreviation for Canada) was designed to

provide network services to the Canadian research, education, and

advanced development community. Any organization, including

universities, corporations, nonprofit organizations and government

agencies, involved in research or education can join the network. It

became operational in 1983 and is administered by CDNnet headquarters

at the University of British Columbia. Small organizations usually

have one link to the headquarters, while larger organizations have

connections to the headquarters and other organizations. The network

has an estimated 175 hosts at some 32 institutions.

The X.400 protocol is used for message handling service, and

mail is the basic application service provided. Most long-haul links

are 2400 bps, although the links vary from 1200 bps to 19.2 Kbps. A

19.2 Kbps link connects the network to the NSFNET backbone in the

United States, at Seattle, WA. There are also interconnections with

CSNET, BITNET and USENET. Funding has come from membership dues and

government grants.

Page 3-9
3.4.1.3 NetNorth

NetNorth, which became operational in 1983 and which is

administered by the NetNorth Consortium, was designed using the same

technology and some of the same basic assumptions used by BITNET in

the United States. Link speeds range from 2400 bps to 9.6 Kbps.

There is a direct 9.6 Kbps link to BITNET in the United States from

the University of Guelph in Ontario to Cornell University at Ithaca,

NY. A proposal to change this connection to a 56 Kbps link from

Toronto to Cornell is being implemented. Such a link would serve

both BITNET and NSFNET users.

3.4.1.4 CA'net

The National Research Council (NRC) in Canada is developing a

new nationwide network, CA'net. This network will provide a

transcontinental leased line backbone connecting regional networks

and will provide more and faster services than the existing Canadian

national networks, NetNorth and CDNnet. The network will have three

levels like NSFNET: a backbone, mid-level regionals, and campus

networks. Backbone link speed development is modeled after the

NSFNET, starting with 56 Kbps and 1.544 Mops links with plans for 45

Mbps links. The TCP/IP protocol is being used, and there are plans

for migrating to ISO/OSI protocols.

A full range of services, including remote supercomputer access,

are being provided. The user population is expected to reach about

30,000 users, at 80 institutions, by the early 1990s. Management is

being directed by a consortium of users, providers and other

participants. It is intended that, in five years, all funding for

the network will come from its users. While CA'net will be primarily

a service network, it will also support network development.

3.4.1.5 REGIONALS

The Alberta Higher Education Network, AHEN, connects a variety

Page 3-I0
of organizations in Alberta, including school boards, hospitals, and

oil exploration companies. This is a relatively small network that

uses low-speed links. A proposal for a high-speed network (i.e.,

1.544 Mbps) has been made.

The British Columbia network, or BCnet, is a regional network

headquartered at the University of British Columbia. It supports

TCP/IP, DECNET and X.25 protocols, and its link speeds range from 9.6

Kbps to 1.544 IVlbps. It has a 19.2 Kbps connection to the NSFNET

backbone at the University of Washington.

The Computer Research Institute of Montreal (CRIM) Network was

developed in the mid 1980s and is a metropolitan 56 Kbps star

network. CRIM uses DECNET and connects various local area networks

at universities in the Montreal area. There are plans to expand CRIM

and to connect it to the new CA'net.

The Ontario Network, Onet, connects the campus networks of six

universities in Ontario. It is a TCP/IP network which provides

access to a Cray supercomputer. The links are typically 19.2 Kbps

leased lines. However, there is a 56 Kbps link from Toronto to the

NSFNET backbone at Cornell. It is expected that Onet will be an

NRCnet regional.

3.4.2 Networks In Mexico

Mexico has two major networks, the ITESM network, named for the

Instituto de Estudioe Superiores de Monterrey, or the Monterrey

Technological Institute of Higher Education, and the UNAM network,

named for the Universidad National Autonomidad de Mexico (the

national university in Mexico City). The networks, which began in

1987, are linked together by a link from a UNAM site in Mexico City

to an ITESM site in Monterrey. University sites are connected to

each other via 9.6 Kbos leased lines, the public X.25 network, or 56

Kbps satellite links. There is a leased line to THEnet in the United

States. Also, plans for two satellite links to NSFNET, via NCAR, are

Page 3-11
being implemented; a 64 Kbps link to Monterrey and a 64 Kbps link to

Antizapan arc planned.

3.5 NETWORKS IN EUROPE

There arc several widely used networks that serve or have served

the continent of Europe. Five examples are listed below under

continent-wide networks. Another network, the European Informatics

Network (EIN) was a mid-1970s attempt to provide a continental

research network in Europe; it no longer exists. There also are

examples of networks that serve several nations, that is,

multi-nation networks.

Many nations in Europe do not have their own research networks.

Belgium, Greece, Iceland, Luxembourg and Portugal only have hosts on

EUnet, and Turkey only has a host on EARN. There have been very few

network connections to the Soviet Union or the Eastern European

countries. Also, these countries, except for the Soviet Union, don't

tend to have their own networks. Bulgaria, Czechoslovakia, the

Democratic Republic of Germany, Hungary and Poland all have

connections to the multi-nation network, IASnet, discussed below.

There are no known systems in Albania or Romania.

Recent changes in the Eastern European political and economic

landscape will have, no doubt, a major impact on the manner in which

scientific research is conducted in these countries. Greater

cooperation with Western Europe and the United States will spurt the

development of communications lines in Eastern Europe. The European

research networks and the U.S. connectivity to these networks will

undergo major expansion as the political and economical gains are

consolidated and the attention is focused on scientific and cultural

endeavors. Already, plans are underway for some Eastern European

countries to join European communications associations. While

interest in developing better communications in these countries is

growing, it is not possible to predict how fast this interest will be

translated into reality.

Page 3-12
3.5.1 Continent Wide Networks In Europe

The best examples of continent wide networks are: EUnet, EARN,

HEPNET, EIN and Ean, and RIPE.

3.5.1.1 EUnet

The European UNIX network, EUnet, .is a European cooperative R&D

network begun in 1982. While EUnet began as an application of the

protocols and software used in USENET and UUCP and while most of its

hosts run UNIX, the network is not restricted to UNIX. Today it uses

UUCP and TCP/IP protocols. EUnet is designed to provide the European

research and development community with a variety of services,

primarily electronic mail and news, and with interconnections to

other networks. EUnet has become an important means of technology

transfer between industry and academia.

The network originally served the Netherlands, Denmark, Sweden,

and the United Kingdom, but has spread throughout Western Europe.

Today, there are over 1200 sites in 19 countries. The network is

growing very rapidly in both sites and throughput. Total network

throughput is estimated at about 3 Gigabytes per month.

The link speeds range from 2400 bps to 64 Kbps. There are

connections from EUnet to EARN, JANET, DFN and other networks within

Europe, plus intercontinental connections to Japan (JUNET), Korea

(SDN), Australia (ACSnet), Malaysia (RanfKoM), New Zealand, Israel,

and North America (CSNET, UUCP, UUNET via 64 Kbps leased line).

Thcrc is a EUnet backbone host in each member country in Europe, and

this host serves as a gateway for communications within its country.

Funds are provided by the owners of the individual hosts and by the

individual users. Currently, talks are being held among EUnet, EARN,

HEPNET and RARE rcprescntativcs about coordinating and intcgrating

networking servicesthroughout Europe.

Page 3-13
3.5.1.2 EARN

The European Academic Research Network, EARN, which was formed

in 1983 using the BITNET model, is a network for Europe, the Middle

East, and Africa. It also is known as the European segment of the

BITNET network. It has hosts in every Western European country, plus

Austria, Yugoslavia, Cyprus, Turkey, Israel, Algeria, the Ivory

Coast, Morocco, Tunisia, Egypt and India. Proposals for accepting

connections from Bulgaria, Hungary and the Soviet Union are being

considered.

As the first general purpose network serving this broad area of

the world, it is widely used for scientific, research, educational

and academic purposes. Today, EARN links more than 500 institutions

and has more than 100,000 users in 24 countries. EARN is an

association registered in France and its directors include one

representative from each member country. Financing is the

responsibility of the EARN nodes in each country.

EARN is based on the same technology used by BITNET and provides

the same services. It uses IBM's Synchronous Network Architecture

protocol, but is committed to migrating to ISO/OSI. Services

provided include interactive messaging, mail and file transfer. The

leased lines on the network range from 2400 bps to 64 Kbps, and the

international links are at least 9.6 Kbps. EARN is directly

connected to BITNET in the United States, forming along with NetNorth

in Canada, a single logical network. EARN also has connections to

CSNET and ESNET in the United States and to DFN, EUnet and JANET in

Europe. Currently, as noted under the EUnet discussion, talks are

being held among EARN, EUnet, HEPNET and RARE representatives about

coordinating and integrating networking services throughout Europe.

3.5.1.3 HEPnet Europe

HEPnet in Europe includes the coordinated set of networking

facilities used by High Energy Physicists in Europe. The network is

Page 3-14
administered by a coordinating committee with a chairperson from the

Organisation Europecnne pour la Recherche Nuclcaire (CERN).

Networking for High Energy Physics is conducted over a variety of

networks ranging from those dedicated to physicists in various

countries to the several multidisciplinary networks in the different

countries. That is,itincludes components of other networks.

The various components of HEPnet Europe are interconnected

through a set of international leased lines. As in the United

States, DECNET is the primary protocol used. SNA, NJE and Coloured

Book protocols are also used, and there are plans to migrate to

ISO/OSI. Services include mail, file transfer and remote login and

job entry. Most dedicated links operate at 64 Kbps. However, there

are plans for the introduction of 2 Mbps links. The CERN connection

(i.e., from Geneva) to the United States HEPNET terminates at the

Massachusetts Institute of Technology in Cambridge, MA. It also has

connections to EARN and EUnet in Europe and to the Internet and SPAN

in the United States.

3.5.1.4 EIN & Eau Europe

The European Informatics Network (EIN) was a mid-1970s attempt

to provide a continental research network in Europe. It no longer

exists.

There are a number of networks in Europe and around the world

that use the Ean (name given to the original X.400 protocol in

Canada) implementation of X.400. In Europe, the association of these

networks is called Ean Europe. Its objective is to establish

communication links for the European community. Most of these links

currently are 9.6 Kbps leased lines.The interconnectivity is growing

throughout Europe.

3.5.1.5 RIPE

EUnet began setting up a continental TCP/IP network called

Page 3-15
Reseau IP Europeen (RIPE) in 1989. It uses TI links from Amsterdam

to France (FNET) and to Stockholm (NORDUnet), and it will have

connection to the NSFNET. Itwill bc similar to NSFNET.

3.5.2 Multi-Nation Networks In Europe

There are two significant multi-nation networks in Europe:

IASnet and NORDUnet.

3.5.2.1 IASnet

IASnet, the network for Socialist countries, is still being

implemented. It is a star network with the central host at the

Institute of Automated Systems (IAS) in Moscow and with X.25

connections to institutes of informatics in Bulgaria, Hungary, East

Germany, Poland, Czechoslovakia, Cuba, Mongolia and Vietnam. Users

at these institutes have access to Soviet and foreign databases.

Access from the center host at IAS to other networks is via an X.75

line to the Austrian PDN and an X.25 line to the Finnish PDN.

Languages used on the network include English, French and Russian.

3.5.2.2 NORDUnet

The Nordic countries have sponsored a number of early networking

projects: Centernet (Denmark), FUNET (Finland), ICEP (Iceland),

UNINETT (Norway) and SUNET (Sweden). Based on work at these

projects, NORDUnet (a networking organization formed in 1985)

established NORDUnet which became operational in 1988. Today,

NORDUnet is an international network that connects the Nordic

countries by connecting local area networks at Scandinavian

universitieswith an internationalbackbone.

The network configuration is a star network centered i

Stockholm, Sweden, where it is connected to the Swedish national

network SUNET. The network has nodes in Lyngby, Denmark (where it is

connected to DENet), Trondheim, Norway (where it is connected to

Page 3-16
UNINETT), and Espoo, Finland (where it is connected to FUNET). The

purpose of NORDUnet is to provide coordinated network services to

Nordic R & D users.

The protocols used are UUCP, TCP/IP, DECNET, NJE and X.25.

Basic services like mail and file transfer are provided; access to

supercomputers is also provided. The star links are 64 Kbps leased

lines. There are connections to NSFNET, HEPNET, CSNET, EARN, and

EUnet. Plans are underway for increasing some link speeds to 2 Mbps

and to provide a connection to Iceland. Migration to ISO/OSI is

expected.

3.5.3 Networks In France

As indicated in Section 2, France, like the United Kingdom and

the Unites States, was involved in the early network development

work. Three of its first networks were CYCLADES, RPC and COSAC.

Networks currently used, to some degree, for research purposes

include FNET, ARISTOTE, S/vlARTIX, PHYNET and REUNIR.

3.5.3.1 CYCLADES & OTHER EARLY NETWORKS

In France, the CYCLADES (Cyclades is an archipelago in the

Aegean Sea, named for its circular configuration, hence the use of

the name for this network) network, developed in the early 1970s, was

designed for both network research and as a support for other

research. CYCLADES, similar in many ways to the earlier ARPANET in

the United States, was coordinated by what is now called the National

Research Institute for Computer Science and Automation. The network

became operational in 1973, grew slowly through the 1970's because of

budget constraints, underwent developmental changes, and established

some international links.

The network used a specially developed protocol, CIGALE, and

provided a wide variety of services. Link speeds ranged from ,1.8

Kbps to 19.2 Kbps, and there were a number of international

Page 3-17
connections (e.g., to London, Rome). CYCLADES was phased out in

1981. This network, did, however, have a significant impact in

France and internationally, on the development of network technology

(e.g., the ISO-OSI model).

Two other French networks, developed relatively early, were RPC

for Reseau Communication par Paquet and COSAC for Communications Sans

Connections. RPC played a major role in the evolution of X.25 packet

networks, and network research was conducted on COSAC during the mid

1980s.

3.5.3.2 FNET

FNET, which is the French branch of EUnet, provides news and

mail service and is similar in several ways to the French research

network ARISTOTE (discussed below). For example, these two networks

serve over 6500 users at public research laboratories, universities,

private research organizations and a number of private companies.

The most frequently used protocol on FNET is UUCP and the typical

services are news and mail. However, new services (e.g., file

transfer) are being planned, and there is a plan to migrate to

ISO/OSI.

The typical link speed is 4800 bps. There currently is a

satellite link to NSFNET, but this link will be changed to a fiber

optic cable link. The Institut National de Recherche en Informatique

et Automatique (INRIA) and the French UNIX Users's Group manages the

network. INRIA pays for much of the cost of the backbone; member

fees pay for the remaining costs. Because of its importance to its

users throughout France, there are plans for improving this network.

These improvements include: use of TCP/IP and ultimately ISO/OSI;

increased speeds; more interconnections with other networks, the

establishment of a permanent organization to manage it.

3.5.3.3 ARISTOTE

ARISTOTE is an acronym for Association de Reseaux Informatique

Page 3-18
en Systeme Totalement Ouvert et Tres Elabore (i.e., Association of

Information Networks in a Completely Open and Very Elaborate

System). The network is managed by a French nonprofit association

whose primary purpose is to facilitate the development of networking

technology. ARISTOTE members, mostly national agencies, are research

institutions with industrial concerns. The typical protocol is

TRANSPAC, and the services include mail and remote login, which have

been available since 1988. Link speeds range from 4800 bps to 64

Kbps. There are interconnections with e.g., FNET, CSNET, and the

Internet.

3.5.3.4 SMARTIX & PHYNET

SMARTIX was designed as an experiment to solve internal needs of

the French National Telecommunications Research Center (CNET). This

network is based on the work at COSAC and uses the COSAC version of

X.400. Services include long-term archiving, access to other

services like telex, and conferencing. SMARTIX's link speeds range

up to 64 Kbps, and it has direct connections to ARISTOTE, and through

ARISTOTE to EUNET, CSNET, and the lnternet. It is funded by the

French government.

PHYNET, which is the network for nuclear physicists in France is

similar to HEPnet in Europe. It uses DECNET and its link speeds are

64 Kbps.

3.5.3.5 REUNIR

REUNIR is an acronym for Reseau des Universites et de la

Recherche (i.e., Network of Universities and Research). The REUNIR

Network connects many French universities and research institutions,

and its basic purpose is operational support of other research. Its

primary participants are the national universities, the National

Center for Scientific Research and national agencies involved in

research, e.g., agriculture, health and medicine. The network uses a

variety of protocols (e.g., TRANSPAC, SNA, and TCP/IP), and provides

Page 3-19
several services, including mail, file transfer, and remote login.

Link speeds range from 4800 bps to 2 Mbps. REUNIR has

interconnections with EARN and FNET.

3.5.4 GERMANY

Germany (i.e., the Federal Republic of Germany) has contributed

significantly to network development. As noted in Section 2, one of

Germany's earlier networks, HMI-NET, is similar to CYCLADES and

ARPANET in that it has been an experimental network and has

contributed to the development of a community of network experts.

Other important networks are Dnet, Germany's national branch of

EUnet, and AGFNET, which connects many of Germany's research centers

and universities.

3.5.4.1 HMI-NET

In Germany, the Hahn-Meitner Institut (HMI) Network (HMI-NET)

was established in Berlin as an experimental networks and was

operational during the mid to late 1970's. This network, like

CYCLADES and ARPANET, helped to develop a community of network

experts and to pave the way for the development of more advanced

networks (e.g., Deutsehes Forschungsnetz or DFN). In fact, one of

the early developers of HMI-NET has recently proposed a

continent-wide fiber optic network with speeds of 100 Mbps and

faster.

3.5.4.2 DFN

The Deutsches Forschungs Netz (DFN), or German Science Network,

is the national research network in Germany. In the early 1980s, a

study by Stanford University recommended the development of a

nationwide network that would provide ARPANET-like services for

Germany, rather than expand BERNET as some had proposed. The

Stanford recommendation was followed, and DFN was begun in the mid

1980s. DFN connects every university, college, and research

Page 3-20
laboratory in Germany. By thelate 1980s it had over 65 hosts.

DFN uses X.400 and other ISO/OSI compatible protocols to provide

a wide variety of services, including mail, file transfer and remote

job entry. Most links are 9600 bps, some are 64 Kbps, but higher

rates are planned. There are links to EUnet, EARN and CSNET.

DFN-Verein in Berlin administers the network, while the Ministry of

Research and Technology (MRT) provides funding. The network's

managers have been involved in the development of ISO/OSI protocols,

and DFN is Germany's representative in RARE.

3.5.4.3 AGFNET

Arbeitsgemeinschaft der Grossforschungseinrichtungen (AGF) is

the Association of National Research Centers, and AGFNET has been its

network. AGFNET, as a backbone network, connects all of AGF research

centers and all of Germany's universities. There are twelve

organizations on the backbone, and each has one host on the backbone

and each has its own network. The total number of users is estimated

at about 10,000.

The network supports multiple protocols (i.e., SNA, ISO/OSI,

DECNET, TCP/IP), and provides a variety of services. Most links are

64 Kbps leased lines, and there are interconnections to other

countries (c.g, Montpellier, France). Because IBM funding ended in

the late 1980s for several of the networks connected to AGFNET, the

networks affected (often sites of large laboratories) have planned to

interconnect their networks to form a German EARN (i.e., DEARN). The

network currently is administered and funded by AGF.

3.5.4.4 REGIONAL NETWORKS: BERNET & BELWU

The purpose of BERNET, started in 1976, is to link all academic

and research institutions in West Berlin. The development of the

network has been based on the work completed on HMI-NET. Today,

BERNET is the Berlin regional part of DFN. It is one of the two

Page 3-21
major regional networks in Germany.

BELWU, in Baden-Wurttemberg, is the other major regional

research network in Germany. It has been operational since early

1988. It uses 140 Mbps optical fiber long-distance trunks to connect

campus Ethcrnets, HYPERchanncl (data link protocol used with Cray 2s)

installations, and FDDI (i.e., Fiber Distributed Data Interface,

network layer protocol) installations. Higher level protocols tend

to be TCP/IP, and the migration to ISO/OSI is planned.

3.5.5 Networks In The United Kingdom

As discussed in Section 2, The United Kingdom conducted some of

the early work in experimental networks and now has a nationwide

research network. Its early experimental network was the National

Physical Laboratories (NPL) Network, and its first major network for

supporting other research was the Science and Engineering Research

Council Network (SERCnet). This early work has influenced the

development of a national research network named JANET and Starlink,

and UKnet.

3.5.5.1 NPL NETWORK

One of the earliest packet switching networks was implemented at

the National Physical Laboratories (NPL) in the United Kingdom in

1968, when the ARPANET was built. An international connection was

established to CYCLADES in 19"/4. This early work influenced the

developed of SERCnet and ultimately, JANET.

3.5.5.2 SERCnet

Initial planning for the Science and Engineering Research

Council Network (SERCnet) actually began back in 1966. SERCnct

progressed through several developmental phases with several names

during the late 1960's and early 1970's and was established as a

research network, named SERCnet, in 1977.

Page 3-22
The Computer Board for Universities and Research Councils

(CBURC), funded by the Department of Education and Science (DES),

began planning in the late 1960s for a network that would connect

regional computer centers. The initial plan called for star networks

using PTT leased lines. Some intersite connections were established

by 1976, and by 1977 when the network was named SERCnct, many

universities and polytechnic sites were connected. About this time

the CBURC and the SERC were making plans for a national backbone

network. In 1984, SERCnet was used as the core of this new network,

named JANET.

3.5.5.3 JANET

The Joint Academic Network, JANET, as noted above, partly grew

out of SERCnet in 1984. Also at this time, the networks of other

major national organizations (e.g., the Natural Environment Research

Council) merged with JANET. That is, JANET was established to

interconnect the local networks in the United Kingdom research

community, including those at the Councils, Universities and

Polytechnics, and to provide access to networks around the world.

Today JANET is the major academic network in the United

Kingdom. Because there was a single ultimate source of funding

(i.e., the Department of Education and Science) for all the networks,

the merging was simplified and facilitated. This consolidation has

led to increased connectivity, new services and reduced overall

COSTS.

JANET is a packet switching network. Local networks connected

to JANET tend to be Ethernets, the long-haul network layer is X.25

over leased lines, and the higher layers use the Coloured Book

protocol. The network can be used to provide access to a computer at

another site, to send mail, to transfer files, or to submit a job

from one computer system to run on another. Services include access

to supercomputers (e.g., a Cray Is and a CDC Cyber 205).

Page 3-23
Currently, the main trunk network speed is 512 Kbps; some

long-distance links are 64 Kbps digital or 48 Kbps analog, and

subscriber lines are mostly 9.6 Kbps. There arc interconnections to

the Internet, Ean networks, EARN, BITNET, UUCP, EUnet, SPAN, and

JUNET. The connection between JANET and NSFNET consistsof a 56 Kbps

digital data circuit between the University of London Computer Center

(ULCC) and the John yon Neumann National Supercomputer Center in

Princeton. The number of registered hosts are estimated to be about

1500, includimg those on local area networks; about 20 hosts are

connected directlyon the JANET wide area network.

Administration is handled by a Network Executive at the SERC,

Special Interest Groups, and a Network Advisory Committee. Usage is

free of charge to members of institutions connected to JANET. JANET

is funded by the Computer Board for Universities and Research

Councils (CBURC). JANET is a member of RARE, and it plans to migrate

to ISO/OSI.

3.5.5.4 Starlink

The Starlink Network, which became operational in 1980, is a

network for astronomers. Its name is derived from its function and

from its original star topology. Starlink, whose purpose is to

provide astronomers with interactive computing facilities, is a

national network with hosts throughout the United Kingdom connected

by JANET links. Starlink uses the DECNET and Coloured Book protocols

over Ethernets and JANET's X.25 leased lines. Services provided

include: mail, file transfer, remote login, and a variety of

/

astronomy applications. The typical link speed is 9.6 Kbps. There

are direct interconnections with HEPNET and SPAN, and indirect links,

via JANET, to other networks. There are about 50 hosts at 19 sites

and about I000 users. The network is administered and funded by

SERC.

3.5.5.5 UKnet

UKnet, which began in 1984, is the United Kingdom (UK) UNIX

Page 3-24
Network. It is the UK's part of EUnet, the European UNIX network.

It is the major network in the UK connecting universities, research

organizations, and commercial sites to the EUnet. Protocols used by

the network are Coloured Book and UUCP. UKnet provides the same

services as EUnet, which are mail, news and access to other

networks. Link speeds range from 1200 bps to 19.2 Kbps. The network

is run from the University of Kent at Canterbury in cooperation with

a users group. While the network has received some government

grants, most funding comes from charges to the user sites. The

network plans to migrate to ISO/OSI.

3.5.6 Networks In Other European Countries

The other European countries which have major networks, used in

some manner for research, are: Austria, Denmark, Finland, Iceland,

Ireland, Italy, Netherlands, Norway, Soviet Union, Spain, Sweden,

Switzerland and Yugoslavia. The research networks in these countries

are described briefly.

3.5.6.1 Networks In Austria

Austria has an academic and research network (ACONET), a

university network (UNA) and local branches of EARN and EUnet. The

EUnet and EARN nodes became operational in the mid 1980s.

The Academic Computer Network (ACONET) was begun in 1986 by the

Austrian Federal Ministry of Science and Research. ACONET, a member

of RARE, is Austria's long-haul research network. It reaches most

research and higher education institutions and has connections to

EUnet and EARN. Administration is centered in Vienna. It uses

special Austrian protocols but plans to migrate to ISO/OSI. Services

provided include mail, file transfer, remote login, and remote job

entry. Its link speeds range up to 19.2 Kbps, and it connects with

UNA, with BITNET via EARN, and USENET via EUnet.The Austrian

University Network (UNA) uses DECNET protocols to connect computers

at Austrian universities.

Page 3-25
3.5.6.2 Networks In Denmark

Denmark has two main networks, DENet, its academic and research

network and DKnet, its branch of EUnet. The Danish Ethernet Network

(DENet) connects many local Ethernets in university departments

throughout Denmark. The network, which is the Danish part of

NORDUnet and which replaced Centernet, provides nationwide access to

computer facilities. Protocols used are TCP/IP and DECNET. Link

speeds are 64 Kbps and 128 Kbps. DKnet is the Danish part of EUnet

and provides mail and news services as does EUnet. The main backbone

machine on the network has four 1200/2400 bps modems and two X.25

lines.

3.5.6.3 Networks In Finland

Finland has one major network, the Finnish University Network

(FUNET), and connections to other major networks around the world.

The purpose of FUNET, established in 1984, is to provide network

services to the Finnish Universities and Research establishments.

This network is star-shaped and is centered and administered at the

Helsinki University of Technology. Universities, private companies

and government agencies use the network.

FUNET uses a variety of protocols, with the most widely used

being TCP/IP and DECNET. Services include mail, conferencing, file

transfer, remote job entry, remote login and interactive graphics;

access to supercomputers is provided. The network uses leased lines,

ranging from 14 Kbps to 64 Kbps, with Ethernet bridges and routers to

connect local Ethernets at Finnish universities. There are direct or

indirect connections to EARN, EUnet, NORDUnet, BITNET, CSNET, NSFNET,

SPAN and HEPNET. Future plans include increasing link speeds to 2

Mbps.

3.5.6.4 Networks In Iceland

The major network in Iceland is the local branch of EUnet.

Page 3-26
There also are connections to EARN and Ean networks. The local

branch of EUnet is administered by a users group, and mail and news

are the main services. The network uses UUCP links over leased and

dial-up lines and X.25 links at speeds ranging from 1200 bps to 9.6

Kbps. The network has connections to NORDUnet.

3.5.6.5 Networks In Ireland

The Republic of Ireland, which was connected to the early COSAC

network, is one of the main centers of EARN and has a national

backbone host on EUNET. Its major networks include HEANET and

EuroKom.

The Higher Education Authority Network (HEANET) was begun in

1985 and is administered and funded by the Irish Higher Education

Authority. The purpose of HEANET is to provide access to network

facilities and to other networks. It currently connects seven

colleges throughout Ireland. The primary protocol is the Coloured

Book and services include mail, file transfer, and remote login.

HEANET uses leased lines on the national PSN. Link speeds range up

to 64 Kbps, and there are interconnections with EARN, Eunet and EARN.

EuroKom is a network for participants in the European Strategic

Programme for Research in Information Technology (ESPRIT) of the

European Community (EC). ESPRIT supports non-competitive research

into software technology, computer integrated manufacturing,

microelectronics, and related areas. EuroKom, which is based in

Dublin, supports many of the ESPRIT projects and other key EC

research initiatives. It provides electronic mail and computer

conferencing services to both industry and universities, and its

links speeds range up to 64 Kbps.

3.5.6.6 Networks In Italy

Italy's national research network is the Instituto Nazionale

Fisica Nucleare Network (INFNET). INFNET's purpose is similar to the

Page 3-27
French network PHYNET and to the European and worldwide network

HEPNET. It uses DECNET protocols and has over 100 hosts. It plans

to upgrade its lines from 9.6 Kbps to 48 Kbps. It has two

international lines to CERN and one to SPAN.

3.5.6.7 Networks In The Netherlands

The Netherlands has two main networks, the national branch of

EUnet and a national research network, SURFnet, which is also the

national branch of EARN. SURFnet, the research and higher education

network in the Netherlands, connects some 85 organizations. The

network's protocols are DECNET and NJE. Its backbone has twenty-five

64 Kbps links; the speed of its other links is 9.6 Kbps. SURFnet is

planning to move to X.400 electronic mail and is working on a

dedicated, nationally managed, X.25 network.

3.5.6.8 Networks In Norway

The major network in Norway is UNINETT. There also are national

components of several other networks. The original UNINETT became

operational in 1978 and was used for both networking research and to

support other research. A new UNINETT was established in 1987 by the

Norwegian Ministry of Cultural and Scientific Affaris to provide

advanced networking facilitiesfor research and development.

The current UNINETT is an ISO/OSI-based research network and

connects the universities in Norway via leased and dial-up lines and

packet switched technoloby. Link speeds have been upgraded recently

to 64 Kbps. Services include mail, file transfer, remote job cntry,

database access, remote login, and teleconferencing. UNINETT has

connections to EUnct, EARN, HEPNET, and the Internet. Today, the

network is working to integrate all research networks in Norway into

one ISO/OSI research network.

3.5.6.9 Networks In The Soviet Union

The Soviet Union has several large networks. Academnet connects

Page 3-28
research and academic institutions in the republics of the Soviet

Union to the Institute for Automated Systems (IAS) in Moscow. The

purpose of this network is to provide access to Soviet and foreign

databases, which is also the purpose of IASnet.

Adonis, still under development, is run by IAS and connects

computer centers in the Soviet Union. ANAS is the administrative

network of the Azerbaijan SSR Academy of Sciences and is used for

information management. ANAS provides mail, remote login and several

other services.

There is a connection between Moscow and San Francisco, known as

the San Franscisco-Moscow Teleport. Links in the Soviet Union are

estimated to range from 2400 bps up to 64 Kbps.

3.5.6.10 Networks In Spain

Spain has a RARE experimental R&D network, a national branch of

EUnet, FAENET (the local branch of HEPNET), and RICA, a regional

academic network. The national branch of EUnet is called Enet, which

was started in 1986 and which is organized as a star with direct

connections to all hosts in the country. The main protocol is UUCP

and mail is the primary service. The speed of international links is

9.6 Kbps. Rapid growth is expected, and plans are being made to

prepare for it. The RARE experimental R&D network is called Ean.

Ean is a national research network that uses Ean software. The

typical link speed is 9.6 Kbps, but there are plans to upgrade lines

with heavy traffic to 64 Kbps. An international link to CERN is

planned.

3.5.6.11 Networks In Sweden

The major network in Sweden is the Swedish University Network

(SUNET), which began in 1980 and which includes several components of

other networks. The purpose of SUNET, which interconnects local and

regional networks at universities in Sweden, is to provide network

Page 3-29
facilities for researchers and teachers of all disciplines. The

operation and management of this network is decentralized.

The SUNET backbone is a star network centered in Stockholm.

There are six 64 Kbps lines interconnecting local Ethernets to one

national Ethernet. An X.25 network provides the backbone; this X.25

network is also used for international traffic. Networks connected

to the SUNET backbone include: a DECNET network coordinated with

NORDUnet, SPAN, and HEPNET; a TCP/IP network with connections to the

Internet; and an NJE EARN network. The network thus uses several

protocols and provides a variety of services.

3.5.6.12 Networks In Switzerland

The national research network in Switzerland is SWITCH and the

national EUnet backbone host is at CERN. SWITCH provides a wide

variety of services to researchers throughout the nation, and its

typical link speeds are 64 Kbps. CERN is one of the networking

centers of the world, and it connects every European continental

network, including HEPNET, EARN, EUnet, and the Ean networks. It is

a testbed for local area networking technology, for interconnecting

networks, and for protocol suites. CERN plays a leading role in

European technology enhancement initiatives.

3.5.6.13 Networks In Yugoslavia

Yugoslavia has one network, the SIS network, which appears to

serve as its research network, and a national backbone on EUnet. SIS

(which probably refers to Social Information System) was developed in

the late 1980s. Eventually, it will provide mail, remote job entry,

file transfer and videotext. Link speeds range from 1200 bps to 19.2

Kbps. The network adheres to ISO standards, is a participant in

RARE, but has no international connections.

3.6 NETWORKS IN ASIA

As noted in Section 2, major networks in Asia include three

Page 3-30
multi-nation networks, the networks in Japan and Korea, and only

modest networks in Hong Kong, India, Indonesia, Israel, Malaysia and

Thailand. The other countries either have only connections to

worldwide or multi-nation networks or no system at all.

The People's Republic of China has several connections to the

rest of the world: a CSNET link to West Germany; a UUCP link to

HARNET in Hong Kong; a 1200 bps Kermit link to Vienna, Austria.

Singapore got the first BITNET node in Southeast Asia. Taiwan, the

Republic of China, has connections to both BITNET and PACNET. There

appears to be AUSEAnet connections in the Philippines and in Sri

Lanka. Cyprus is an EARN member. Mongolia has a connection to

IASnet. There arc PDNs in Bahrain, Iraq, Qatar, Saudi Arabia and

United Arab Emirates. There are CGNET (see Africa below) subscribers

in Bandladcsh, Nepal and Sri Lanka.

There are no known systems in Brunei, Cambodia, the Democratic

People's Republic of Korea, Democratic Yemen, Iran, Jordan, Laos,

Lebanon, Myanmar, Oman, Syria, Vietnam, or Yemen.

3.6.1 Multi-Nation Networks In Asia

There are three multi-nation networks in Asia:

GULFnet, and PACNET.

AUSEAnet,

3.6.1.1 AUSEAnet

AUSEAnet, which covers most of Southeast Asia plus several other

countries, is a network for a joint microelectronics Very Large Scale

Integration (VLSI) project among the Association of South East Asian

Nations (ASEAN) countries (i.e., Brunei, Indonesia, Malaysia, the

Philippines, Singapore and Thailand) and Australia. The purpose of

this project, which started in 1986, is to permit electronic

submission of VLSI designs to Australia and to exchange information

about microelectronics techniques. Most funds come from the

Australian government. AUSEnet uses UUCP and SUN-III over

international X.25 networks, and most of its links are 1200 bps.

Page 3-31
3.6.1.2 GULFnet

GULFnet is the Middle East segment of the BITNET Network, It

was established in 1985, and connects 10 academic and research

institutions in Kuwait and Saudi Arabia. It uses the same technology

and provides the same services as EARN and BITNET, but is not

interconnected to them. Link speeds range up to 9.6 Kbps.

3.6.1.3 PACNET

PACNET is the Pacific and Asian academic recta-network serving

Australia, Hong Kong, Indonesia, Japan, South Korea, Malaysia, New

Zealand, Singapore, and Taiwan. PACNET is made up of the networks of

the countries it serves. It is a logical grouping of Pacific hosts

and organizations with no centralized administration or funding. It

is not yet fully operational. It ultimately will connect the Asian

and Pacific sites with Canada via CDNnet, Europe via EUnet, and the

United States with CSNET and NFSNET. Currently, most connections are

2400 bps dial-up links and mail and news are the only services

generally supported.

3.6.2 Networks In Japan

As indicated in Section 2, there are a wide variety of networks

in Japan including N-I, NACSIS, JUNET, Kogaku-bu LAN and Sigma.

Also, many of the international networks (e.g., BITNET, CSNET, UUNET,

HEPNET) reach Japan.

There was little communication by personal computer in Japan

until the privatization of Nippon Telegraph and Telephone (NIT) and

the corresponding deregulation of the public telephone system in

1985. Since then, networking activity in Japan has increased

significantly.

One of the major problems being handled by Japanese researchers

in networking involves the development of hardware and software that

Page 3-32
can handle the Japanese language. Today, the Japanese government is

encouraging implementation of campus networks and is funding two new

high-speed international links to the United States and Europe.

These links are being developed in cooperation with the U.S. NSF.

3.6.2.1 N-1

The oldest major network in Japan is N-I which became

operational in 1981 and which is an inter-university network. It

uses its own N-I protocols, and its services include remote login and

remote job entry, but not mail. Line speeds are typically 9.6 Kbps,

but range from 4.8 Kbps to 48 Kbps.

3.6.2.2 NACSIS

The National Center for Science Information Systems (NACSIS)

Network, established in 1987, is the likely successor to N-I. It is

a tree-shaped network with direct links to the component

institutions. The network connects Inter-University Computing

Centers throughout the main Japanese islands and gives researchers

access to a wide range of computing facilities including

supercomputers.

NACSIS uses the N-I protocols and provides the same services as

N-I does, i.e., remote login and remote job entry. Some links are

converting to TCP/IP protocols. The link speeds of the links to the

component institutions are 48 Kbps, and the speeds of links closer to

origin range up to 768 Kbps.

3.6.2.3 JUNET

Today, the major nationwide researh network in Japan is JUNET

which was begun in 1984. This network's purpose is to promote

information exchange among Japanese researchers and with researchers

outside Japan. It also provides a test environment for research in

networking. JUNET connects major universities and research

organizations through Japan; it is concentrated in Tokyo and Osaka.

Page 3-33
The common protocol is UUCP, some links use TCP/IP, and there

are no clear plans to migrate to ISO/OSI. Services include only mail

and news. JUNET's 2000 nodes in about 200 organizations are

connected via 2400 bps or 9.6 Kbps dial-up lines through UUCP; via

9.6 Kbps, 64 Kbps or T-I leased lines with TCP/IP; and via X.25 for

interhational connections. There are intcrconnections to EUnet,

USENET, UUCPnet and CSNET. A connection to SURAnet on the NSFNET and

one to Asianet (BITNET) are planned. Administration is handled by

the major backbone hosts, and each host host's connection costs are

paid by its institution.

3.6.2.4 Kogaku-bu LAN & Sigma

Other networks in Japan include Kogaku-bu LAN and Sigma. The

University of Tokyo established Kogaku-bu LAN in 1987. This network

uses TCP/IP over a 100 Mbps fiber-optic backbone that connects

several local area networks running Ethernet. Currently, 400 Mbps

fiber-optic technology is being developed. Sigma, started in 1987,

is a research and development testbed network designed for use in the

Sigma Project whose purpose is to produce a standard workstation

environment for use in Japan. The basic protocols are TCP/IP.

3.6.3 Networks In Other Asian Countries

Korea has been developing a significant research network. Other

Asian countries which have modest, but important, networks, used in

some manner in research, arc: Hong Kong, India, Indonesia, Israel,

Malaysia, and Thailand.

3.6.3.1 Networks In Hong Kong

The national research network in Hong Kong is the Hong Kong

Academic and Research Network (HARNET) which became operational in

1986. It serves research and academic institutions in Hong Kong by

providing them with connections in Hong Kong and to the rest of the

world. HARNET is a star-shaped network whose links are either UUCP

Page 3-34

m
over dial-up 1200 bps lines or PDN 2400 bps lines, or DECNET over 9.6

Kbps leased lines. Services include mail, news, file transfer and

remote Iogin. There are interconnections with Korea (via SDN),

Australia (via ACSnet), Canada (via CDNnet), United States (via

CSNET), and the United Kingdom (via JANET).

3.6.3.2 Networks In India

Currently, there is much planning activity in India, but few

actual networks. The National Informatics Centre (NIC) is developing

a network, NICNET, that will provide information services to various

government agencies. Its links speeds will be either 1200 bps or 9.6

Kbps. The government is also developing an academic and research

network, ERNET, to connect computing resources at academic and

research institutions. ISO/OSI protocols are being used and initial

services provided will include mail, file transfer, remote login, and

database access. The last mile problem is significant in India, and

the telephone system cannot support a wide-area network. Link speeds

are expected to range up to 64 Kbps, and interconnections to other

networks are planned.

3.6.3.3 Networks In Indonesia

Indonesia is developing a national research network called

UNInet, a university research network. It is expected that some 45

government sponsored universities will be interconnected by this

network.

3.6.3.4 Networks In Israel

Israel has a PDN, a commercial network, and a branch of EARN,

called ILAN, or Israeli Academic Network begun in 1984. ILAN plans

to migrate from NJE protocols to TCP/IP and eventually to ISO/OSI.

Currently, services include mail, chat, and a PC library server.

Page 3-35
3.6.3.5 Networks In Korea

The major national network in the Republic of Korea is the Korea

Research Environment Open Network (KREONet). An earlier network, the

System Development Network (SDN), was begun in 1982. Korea is also

the center of PACNET and has connections to BITNET, UUNET and CSNET.

Starting in 1982, SDN served as a backbone network that

interconnected local area networks, provided network facilities for

communication and served as an R & D test environment. In 1988, the

National Academy and Research Network Planning Group established

KREONet as the nation's backbone network. It will link all the

research and development institutes for improved research

productivity and science and technology advancement in Korea. It is

being developed in three stages between 1988 and 1996, and will

require about $115 million. A T-I backbone will be in place in 1991,

and peripheral sites will be connected to the backbone via links

ranging from 19.2 Kbps to 56 Kbps. Today, the network provides the

following services: e-mail, database access, and file transfer. The

primary network protocol is TCP/IP, with migration to OSI

anticipated. Links to overseas research networks are planned.

3.6.3.6 Networks In Malaysia

The national research network in Malaysia is called Rangkaian

Komputer Malaysia, or RangKom. The purpose of this network, which

began in 1987, is to promote communication in research organizations

and universities, coordinate public databases, and assist in network

research projects. Most universities connect to the network through

their own campus networks. UUCP is its primary protocol, and a

migration to TCP/IP is expected. Services include mail, file

transfer and news. Most traffic runs over the Malaysian Packet

Switched Data Network or leased lines. Most Malaysian lines are run

at 1200 bps, and most leased lines are 4.8 Kbps or 9.6 Kbps.

Transmission speeds of 64 Kbps are planned. RangKom is the Malaysian

part of AUSEAnct, and there are international connections to the

United States,the Netherlands, Australia,Korea, and Indonesia.

Page 3-36
3.6.3.7 Networks In Thailand

The national academic network in Thailand is the Thai Computer

Science Network, or TCSnet. It has connected several universities

since 1988, but has no dedicated funding since traffic is low.

Connections are made by telephone dial-up at 1200 bps or 2400 bps.

The Australian SUN-III protocols are used, and the services include

mail, file transfer and remote job execution. There is a connection

to UUNET.

3.7 NETWORKS IN AUSTRALIA/PACIFIC

There are two multi-nation networks in this area, and both

Australia and New Zealand have important research networks.

3.7.1 Multi-Nation Networks In Australia/Pacific

The multi-nation networks in this area are PACCOM and SPEARNET.

3.7.1.1 PACCOM

PACCOM is an attempt to build a Pacific regional internet. This

network is making use of the emerging fiber-optic cable plant in the

Pacific. Hawaii is at the center of this network because most of the

fibers pass through Hawaii. Hawaii is also the logical choice for

the center becasue it is the home of the largest collection of

optical telescopes in the world, has advanced research facilities and

has a 56 Kbps link to JPL..

The major protocol being used is TCP/IP, but DECNET and others

will be supported. The New Zealand link is a 19.2 Kbps link, the

Australian link is at 64 Kbps, and the link to the U.S. West Coast is

a 512 Kbps link. All links are or eventually will be fiber- optic

links. Links are planned to Japan and to other regions in the

Pacific. Funding is coming from NASA, NSF and the State of Hawaii.

Page 3-37
3.7.1.2 SPEARNET

The South Pacific Educational and Research Network, SPEARNET,

was started in 1986 by the universities in Australia and New

Zealand. The purpose of SPEARNET is to improve computer based

facilities available for teaching and research. SPEARNET is the main

network in New Zealand where all of its universities have been

connected. The network uses the Coloured Book protocols. Services

include mail, remote login, file transfer, conferencing and remote

job execution.

Most links run at 2400 bps or 9.6 Kbps. International

connections between Australia and New Zealand and to other countries

use the international X.25 network. It is expected that SPEARNET

will migrate to ISO/OSI protocols, and there are plans for making the

network into a national backbone research network, like NSFNET or

BITNET in the United States or like RARE or EARN in Europe. A 2 Mbps

backbone with costs shared by participants is anticipated.

3.7.2 Networks In Australia

There are a number of networks in Australia:

QTInet, VICNET and AARNet.

ACSnet, ABN,

3.7.2.1 ACSnet

ACSnet, which began in 1979, is the major network in Australia

connecting universities and research organizations. It spans the

continent and connects about 600 computers. It uses the Sydney UNIX

Network (SUN) III protocols. ACSnet services include mail, file

transfer, remote printing, and USENET news. Most connections are

over leased lines, local area networks, or the Public Switched

Telephone network. Most links run at 2400 bps. There is no central

planning or government funding. Each host pays for its own links.

There is a 64 Kbps leased line to the University of Hawaii that

allows access to the Internet. There are also connections to CSNET.

Page 3-38
3.7.2.2 ABN, QTInet, & VICNET

The Australian Bibliographic Network (ABN) is operated by the

Australian National library. The Queensland Tertiary Institution

Network (QTInet) connects institutions of higher education via leased

lines at speeds of 2400 bps to 9.6 Kbps. VICNET is a network

connecting the Victorian Colleges of Advanced Education and

Institutes of Technology. The University of Queensland has both

DECNET and TCP/IP networks.

3.7.2.3 AARNet

Plans for a conventional multi-protocol network around Australia

are currently being implemented. This network, called AARNet for

Australian Academic and Research Network, will links colleges and

universities in Australia, will use 48 Kbps lines, and will have a

connection to the Hawaii segment of the Internet.

3.7.3 Networks In New Zealand

Most of the networking activities in New Zealand are academic or

research in nature, and they involve the universities, the Department

of Scientific and Industrial Research (DSIR), and the Ministry of

Agriculture and Fisheries. DSIRnet, named for DSIR, became

operational in 1977 and uses a number of protocols (e.g., DECNET,

Coloured Book). Most of the mail between the DSIR and the outside

world passes through DSIRnet. There are two gateways from New

Zealand to the rest of the world; one is a CSNET connection from

Waikato and the other is a UUNET and ACSnet connection from Victoria

University. Most links are relatively slow (i.e., 2400 bps), but, a

unified national research network is being planned.

3.8 NETWORKS IN CENTRAL & SOUTH AMERICA

As indicated in Section 2, the situation in Central and South

Page 3-39
America is similar to that in Asia (especially Southeast Asia).

There is a growing interest in networking, but there are few

operating networks. In Central and South America, there are two

multi-nation networks and links to other networks.

Puerto Rico has an active local branch of FidoNet called RED.

The Center for Population and Family Health (at Columbia University)

uses a Kermit connection to reach Haiti. There is a connection to

IASnet in Cuba. There is a BITNET node in both Argentina and Chile.

Brazil is planning to create an academic network to connect research

centers in universities and industry and government laboratories.

There are no known networks in Belize, Bolivia, Colombia, Ecuador,

French Guiana, Guyana, Paraguay, Peru, Surinam, Uruguay, or

Venezuela.

3.8.1 Multi-Nation Networks In Central & South America

The two multi-nation networks in Central and South America are

CARINET and CATIENET.

3.8.1.1 CARINET

CARINET, which began in 1982, is a general communications

network used by business and development organizations in Central and

South America, the Caribbean, Africa, the Middle East, Asia, Europe

and North America. It has users in some 32 countries, concentrates

on the less industrially developed regions, and has about 500 direct

users. While the network serves much of the world, it focuses on

Central and South America, and the languages used on the network are

Spanish and English. CARINET is accessed via X.25 international

PDNs, with a link speed of 1200 bps. It is used for accessing

libraries, databases, news, mail, coordinating disaster assistance,

and as a means for technology transfer. It was created by

Partnerships for Productivity (PFP), a non-profit corporation

specializing in Third World economic development. PFP sold CARINET

in 1987 to a consortium that has made it an independent for-profit

Page 3-40
corporation. Today, its purpose is still to support development, and

all funding is from fees charged to the users involved in the

development.

3.8.1.2 CATIENET

CATIENET is named for the Centro Agronomico Tropical de

Investigacion y Ensenanza, or Tropical Agricultural Research and

Training Center, a regional organization headquartered in Costa

Rica. It was created in 1973, countries have joined it throughout

the years, and eventually all Spanish-speaking Central American

countries will participate in the network. Today, the Dominican

Republic, El Salvador, Guatemala, Honduras, Nicaragua, and Panama

participate in CATINET. Its major purpose is to provide facilities

for exchanging information about agriculture and forestry and to

share computer resources. Services currently include mail and file

transfer; planned services include batch remote job entry and

interactive database access. Like CARINET, its links speeds are

relatively slow (i.e., 1200 to 2400 bps).

3.9 NETWORKS IN AFRICA

There are very few major networks in Africa. There is one

multi-nation network, and Egypt and Tunisia each have one main

network.

Ethiopia, the Ivory Coast, Mali, and Niger each have connections

to CGNET. Algeria, the Ivory Coast, and Morocco each has an EARN

connection. Senegal has a packet radio network. Kenya is setting up

a PeaceNet type network. South Africa apparently has internal

networks, but external connections are few, as requests to connect to

major worldwide networks (e.g., EARN and BITNET) have been turned

down. There are no known networks in Cameroon, Libya or Nigeria.

Page 3-41
3.9.1 Multi-Nation Networks In Africa

The one multi-nation network in Africa is called CGNET

(Consultative Group Network). CGNET is a conferencing system founded

in 1985 by the Consultative Group on International Agricultural

Research (CGIAR). The purpose of the network is to help improve food

production in developing nations. The networks main machine is

located in Palo Alto, California, and it connects 130 remote outposts

in more than 70 countries, all involved in agricultural research. It

serves the same countries as CARINET, plus others including

Bangladesh, Burkina Faso, Ethiopia, India, the Ivory Coast, Mali,

Niger, Sri Lanka, and Zimbabwe. Most countries use PDNs, but some

use international telephone direct dialing or Kermit links. Link

speeds range up to 9.6 Kbps. The agricultural research is primarily

sponsored by a consortium of international agricultural research

centers, which in turn, are sponsored by the United Nations and the

World Bank.

3.9.2 Networks In Egypt

Egypt has a PDN and a general purpose network (ENSTINET), and is

a member of EARN. ENSTINET is the Egyptian National Science and

Technology Information Network. Its link speeds range up to 9.6

Kbps, and it has connections to EARN and BITNET.

3.9.3 Networks In Tunisia

Tunisia has one main network, Afrimail, initiated by Tunisia and

the Canadian government in the late 1980s. It has a connection to

EARN and planned connections to African and Arab institutions. Its

link speeds are relatively slow, i.e., 1200-2400 bps.

3.10 SUMMARY

Summaries of the eighty-four international research networks,

Page 3-42
which were selected and described in this section, are presented in

Exhibits 3.2 and 3.3. The location, network name and link speeds for

the eighty-four networks are listed in Exhibit 3.2. These networks

are summarized by coverage extent, major geographical area and link

speed in Exhibit 3.3.

Coverage extent is defined in terms of four groups: worldwide,

continent-wide, multi-nation and single nation. About four-fifths of

the selected networks serve a single nation. The other one-fifth

serve either several nations, an entire continent, or most of the

world. The world-wide networks have the lowest maximum link speed,

while networks serving a single nation have the highest maximum link

speed. Across all groups, link speeds range from 1.2 Kbps to 1.544

Mbps. The only exceptions are a limited distance 140 Mbps network

linking high speed local area networks at several West Germany

universitiesand two localarea experimental networks in Japan.

As noted earlier in this section, seven major geographical areas

of the world were used to group these networks. These areas are:

Worldwide, North America, Europe, Asia, Australia/Pacific, Central

and South America, and Africa. About half of the networks are in

Europe, and the other half are distributed across the other major

areas. The networks with the highest maximum link speeds arc in

Europe (Germany) and Asia (Japan). The networks with the lowest

maximum link speeds are in Central and South America and Africa.

Networks were also grouped by maximum link speed. The three

groups of link speeds arc: 1.2 Kbps to 19.2 Kbps; 4g Kbps to 768

Kbps; and 1544 Kbps to 140,000 Kbps. About half of the networks fail

into the category with the lowest link speeds. Only about ten

percent have maximum link speeds of 1544 Kbps or higher.

These descriptions are used in Section 4 to help determine the

current and future internationallinks and trafficvolumes.

SECTION 4

UNITED STATES INTERNATIONAL RESEARCH

NETWORK TRAFFIC FLOW

4.1 OVERVIEW

4.1.1 Purpose

The purpose of this section is to provide estimates of the

United States' international research network connectivity

requirements. The estimates are based on the current and future

traffic flows, between the United States research networks described

in a previous study (i.e., the U.S. Domestic Research Network Study)

and the international research networks (i.e., those outside the

United States) described in Section 3. The estimates of current and

future traffic flows presented in this section will be used, along

with information on recent changes in United States research networks

and in National Research and Education Network (NREN) plans, to

describe new current and future integrated research networks (IRNs).

This section covers two major topics: the current international

research network traffic flow, and the future international research

network traffic flow.

4.1.2 Approach

Estimating the current and future traffic flows between United

States and international research networks included the following

activities: selecting the measure of traffic flow; identifying the

current international links and specifying their speeds; determining

the current link speeds of the selected international networks;

estimating the future link speeds of these international networks;

and projecting the future link speeds of the international links.

Based on a review of information on the selected international

Page 4-1
networks and on the international links, it was determined that

installed capacity would be the best measure of traffic flow. As

with the United States research networks, estimates of traffic loads

or of peak hour traffic were not available for the international

networks and for the international links.

To identify the current United States-international links three

activities were conducted. First, managers of the United States

networks were asked to identify all of their links with research

networks outside the United States. Next, information on the

selected international networks was reviewed to identify links with

the United States research networks. Lastly, records of

international links were obtained from members of the Coordinating

Committee For International Research Networks (CCIRN) and members of

the FNC Engineering Planning Group (FEPG). These records served as

the basis for the specification of the international links. The

findings from the first two activities were used as supportive data.

The current link speeds of the international links were obtained

from the records on the international links. The current link speeds

of the selected international networks were obtained from the

international network descriptions presented in Section 3. The

future links speeds of the international networks and of the

international links were based on the future plans for these networks

and links. The factors influencing the increase in link speeds are

described below in the section on the future international traffic

flow.

4.2 CURRENT INTERNATIONAL TRAFFIC FLOW

As noted above, the current traffic flow, between the United

States research networks and the international networks was estimated

by identifying and specifying the link speeds of the international

links connecting these two groups of networks. That is, the

installed capacity of these international links, along with the link

Page 4-2
capacity of the selected international networks, was used to develop

a picture of the current international traffic flow.

4.2.1 Current United States-International Links

The current United States-International links are listed in

Exhibits 4-1 and 4-2. In Exhibit 4-1, the links are organized by

foreign country, while in Exhibit 4-2, the links are organized by

United States city. In both exhibits, the following information is

provided for each link: name of foreign city, name of United States

city, name and purpose of United States network to which the link

connects, and the speed of the link.

4.2.1.1. Current International Links By Foreign Country

As indicated in Exhibit 4-1, there currently are 77 United

States-international links that connect United States cities to 48

cities in 18 countries. The numbers of links between the United

States and each of the various countries, and cities within each

country, are as follows: Canada-ll/5 (i.e., 11 links, 5 cities),

Mexico-4/3, France-ll/6, Germany-13/6, United Kingdom-6/5, Other

Europe-15/ll, Japan-7/3, Other Asia-2/2, Australia/Pacific-2/2,

Central and South America-6/5, and Africa-0. As noted in the

footnote to Exhibit 4-1, these links do not include any M/LNET links

or any unique CSNET links.

4.2.1.2 Current International Links By United States City

Exhibit 4-2 shows that these 77 United States-international

links connect 22 United States cities to 48 cities outside the United

States. Over half of the 77 links originate from two United States

cities: Greenbelt, Md-29 NASA network links; Princeton, NJ-15 BITNET

and NSFNET links. Only three other cities have at least three links

originating from it: Chicago, IL-6 DOE links; Ithaca, NY-3 NSFNET

links; and Honolulu, HI-4 NASA network links. The other 17 cities

have either one or two international links.

4.2.1.3 Current U.S.-International Links By U.S. Networks

The numbers of links from each of the United States networks are

as follows: SPAN/NSN-34, BITNET-16, NSFNET-13, ESNET-10, DRI-3, and

EUNET-I. That is,about 45% of the links arc NASA network links.

4.2.1.4 Current U.S.-Internatlonai Links By Link Speed

The speeds of these international links range from 9.6 Kbps to

1.544 Mbps. The information in parentheses following the link speed

for several international links refers to either the installation

data (i.e.,the link has not yet been installed) or a planned link

speed (i.e.,a higher link speed about to be installed). The numbers

of links by speed are as follows:

Link Speed (KbDs} _Number of Links

9.6 38

14.4/19.2 4

56/64 31

128 2

256 1

1544 l

Thus, over half of the links are 19.2 Kbps or slower, and there

currently is only one T-l internationallink.

4.2.2 Current International Network Link Speeds

As noted earlier, in addition to information on the current

United States-international links, information on the current link

speeds of the selected international networks was needed to develop a

picture of the international traffic flow. The current link speeds

of the selected international networks were presented in Section 3

(See Exhibit 3-2 and 3-3). The information on current international

links and networks is used in the following section to develop

projections of the future international traffic flow. It also will

be used, with information on changes in United States networks, to

describe, in Section 6, a new Current IRN.

Page 4-11
4.3 FUTURE INTERNATIONAL TRAFFIC FLOW

The future international traffic is anticipated to grow because

of growth in the international networks. The growth will be in the

number of networks as well as in the capacities of networks.

Therefore, to estimate the future international traffic flow,

projections were made of the future link speeds of the international

networks the international links. These projections were based on

four sources of information: CCIRN drafted policy, FEPG proposed

policy, CCIRN perspective on worldwide research network requirements,

and major factors affecting international network requirements.

These four groups of information and the guidelines for developing

projections are described below. Then the projections of the speeds

of the international networks and of the United States-international

links are presented.

4.3.1 Basis For Projecting International Traffic Flow

As noted above, the projection of international traffic flow was

based on CCIRN drafted policy, FEPG proposed policy, CCIRN

perspective on worldwide reserch network requirements, and major

factors affecting international network requirements. These topics

are described below.

4.3.1.1 CCIRN Policy

Of special significance to the current study is a recently

drafted CCIRN policy on intercontinental leased lines. The following

are the key points of this policy:

The CCIRN considers that improved coordination of the ordering

and operation of intercontinental leased lines will have

significant benefits in terms of cost savings and improved

service levels for the research community.

. It expects its members to inform and consult the CCIRN on the

Page 4-12
future plans of the organizations, which they represent, in

respect to the statement in "I." The CCIRN expects proposals for

new leased lines to take account of the following guidelines:

a. Leased lines should be shared to the extent that this is

permitted by applicable and international regulations and the

policies of the funding organizations.

b. To the extent that intercontinental links are considered

"infrastructural" there should be an equitable sharing of

costs; to the extent that links are established for specific

projects,they should be funded by those projects.

c. Links that are used for infrastructural purposes should be

connected at the highest appropriate level in the network

hierarchy.

d. The proposal should include a technical review of the effect

the link isexpected to have on the interconnected networks.

c. Operation of the links should be on the basis of an agreed

written document. Day-to-day management should be the

responsibility of a single organization if possible and

appropriate.

4.3.1.2 FEPG Proposed Policy

A similar policy was recently proposed by the FEPG, which was

set up to assist the FNC in translating its policy goals into

technical programs that can be implemented. The FEPG policy was

developed in parallel with that developed by the CCIRN and was

developed because of the need for better management and support.

Such support has been difficult because of the large distances

involved, the need to work with a number of carriers, time zone

differences,language barriers,and lack of a shared culture.

The following are the proposed FEPG guidelines for

U.S./internationalconnections:

I. The U.S. side should connect to an agency backbone network to

avoid multi-administration problems.

Page 4-13
2. There should be one primary link between any two countries.

. Administration should include 24-hour 7-day coverage on both

sides, a power supply that cannot be interrupted, and agreement

to a single management of components on each end.

4.3.1.3 CCIRN Worldwide Perspective

The CCIRN envisions a worldwide research network that ultimately

will provide high speed, high quality service to researchers

throughout the world. While there is worldwide connectivity today,

the quality of this service varies tremendously from region to region

and country to country within regions.

The future topology of the worldwide research network is

expected to be similar to the United States' NSFNET which has a

backbone, regional networks and local area networks. For the

worldwide network topology, the backbone would connect countries, the

regionals would be the country networks, and the local networks would

be networks connected to a backbone within a country.

An example of efforts leading to such a worldwide topology is a

RARE proposed IXI Project which would provide improved services

throughout Europe. A proposed backbone for this IXI Project would

connect the Netherlands with Switzerland, using two 2 Mbps backbone

links. Switzerland, in turn, would have 64 Kbps links to networks

within Switzerland and to networks in countries such as Austria,

Greece, Italy, Spain, and France. Similarly, the Netherlands would

have 64 Kbps links to networks in the Netherlands and 64 Kbps or 2

Mbps links to networks in the Scandinavian countries, Germany,

Brussels, Luxembourg, Ireland and the United Kingdom. This is only

one of several possible topologies for an improved European network.

The United States likely would have T-I connections to the United

Kingdom, Germany and Switzerland.

Page 4-14
4.3.1.4 Factors Affecting Link Speeds& Connectivity

In addition to these events, noted above and taking place at the

international level, several major factors will influence the

requirements for increased link speeds and services for each of the

international networks described in Section 3 and for the

international links described above in Section 4.2. These factors

include those related to an increase in cooperative worldwide efforts

and to an increase in sophistication in environmental, energy,

medical and space studies. The following are some examples:

1. The ever increasing gl0balization of the impacts of each nation's

activities will encourage more worldwide cooperation and will

lead to increased network requirements.

2. The recent breakdown of barriers with Eastern Block countries

will stimulate a need for more and better research networks among

all nations.

3. The general increase in m¢lti-nation research efforts for a wide

variety of reasons including both business and government goals.

4. The increase in network requirements for 10rig-term environmental

research (LTER) efforts having worldwide implications and

requiring worldwide cooperation.

5. The increase in network requirements for space research,

including that involving deep space projects and the Earth

Observing System Platforms projects, many of which will involve

researchers worldwide.

6. The increase in network requirements for medical research, e.g.,

for the human genome experiments involving the mapping of genes.

7. The increase in network requirements for energy research,

especially that involving new energy sources and their impacts on

the environment.

Page 4-15
. The current, ongoing network technology research and development

in the United States and other highly industrialized countries

will encourage network development in other countries.

4.3.1.5 Summary Of Basis For Link Speed Projections

The future link speeds for the selected international networks

and for the international links are based on the following

expectations which reflect the events and trends discussed above:

1. |nternational orlanizations like the CCIRN will encourage

worldwide network development and coordination.

. World events are leading to an increase in multi-nation and even

global Cooperative research efforts which will require increased

connectivity.

3. Specific research in the areas of the environment, enerttv.

medicine and space are demanding more advanced network functions

and new network applications.

4. Network technolottv research and development will encourage and

facilitate network development worldwide.

4.3.2 Guidelines For Projecting Future Link Speeds

Projections for the future link speeds for the international

networks and the international links are presented below. First, the

guidelines used to develop these projections are outlined. These

guidelines were based on the events and trends summarized above.

4.3.2.1 Guidelines For Projecting International Network Link Speed

The following guidelines were used when projecting the future

link speeds of the international networks:

Page 4-16
l° All nations, currently represented by the list of selected

international networks, will eventually move toward a nationwide

research network.

2. The link speeds of the backbones of these nationwide networks

will progress from the networks current speeds, ranging from 9.6

Kbps to 64 Kbps, to higher speeds, ranging from 45 Mbps to 5

Gbps; for most networks this progression would involve

intermediate steps at various slower link speeds including: 64

Kbps, 1.544 Mbps, 45/90 Mbps, 274/564 Mbps, and l Gbps.

3. Only the backbone of these nationwide networks will be projected

in thissection.

4. While many nations, currently not represented by the list of

selected international networks, are expected to develop networks

sometime in the future, they will not be considered in this

section. When describing the new Future IRN in Section 6, such

future development will be considered.

4.3.2.2 Guidelines For Projecting Speeds Of International Links

The following guidelines were used when projecting the future

speeds of the United States-international links:

I. The United States-international links will be consolidated.

. The speeds of these consolidated links will progress from their

initial speeds in 1991 of 9.6 Kbps-l.544 Mbps to 2010 speeds of

45 Mbps-5 Gbps; for most consolidated links, this progression

will involve intermediate steps at various slower link speeds

including: 64 Kbps, 1.544 Mbps, 45/90 Mbps, 274/564 Mbps, and l

Gbps.

3. Only the consolidated links will be projected in this section.

4. While new links will be established to provide connectivity with

Page 4-17
nations, currently not represented by the list of selected

international networks but which are expected to develop networks

sometime in the future, these possible future links will not be

considered in this section. However, they will be considered

when describing the new Future IRN in Section 6.

4.3.3 Projections Of International Network Link Speeds

Projections have been developed for 1991, 1996, 2000 and 2010.

These benchmark years were selected so that these international

projections could be used with the information developed in the

previous U.S. Domestic Research Network Study.

4.3.3.1 1991 Projections Of International Network Link Speeds

The 1991 projected link speeds for the international research

networks are presented in Exhibit 4-3 and summarized in Exhibit 4-4.

As explained in the guidelines outlined above, only one link speed is

projected for each location (i.e., nation, multi-nation, continent,

or world), and this link speed is for the backbone for the location.

A total of 36 projections were made for 1991 and for each of the

later benchmark years which are discussed below.

It appears that most of the international networks are several

years behind the United States in terms of network link speed. As

indicated in Exhibit 4-3, in 1991, backbone link speeds range from

9.6 Kbps to 1.544 Mbps. Exhibit 4.4 shows that, in 1991, about half

of the international networks are expected to have only a 9.6 Kbps

backbone, about one-third are expected to have a 64 Kbps backbone,

and only about one-seventh are projected to have a 1.544 Mbps

backbone.

-,pc

The impetus for the four 1.544 Mbps backbones are cooperative

efforts between the United States and Japan and similar efforts among

European nations. The United States/Japan efforts will stimulate the

development of Japan's 1.544 backbone and the Australia/Pacific

4.3.3.2 1996 Projections Of International Network Link Speeds

The 1996 projected link speeds for the international research

networks are presented in Exhibit 4-5 and summarized in Exhibit 4.6.

The same 36 locations (i.e., nation, multi-nation, continent, or

world) used to project 1991 link speeds are used for 1996.

As indicated in Exhibit 4-5, in 1996, backbone link speeds range

from 64 Kbps to 45 Mops. Exhibit 4-6 shows that, in 1996, about

thirty percent the international networks are expected to have a 64

Kbps backbone, about thirty percent are expected to have a 1.544 Mops

backbone, and about forty percent are projected to have a 45 Mbps

backbone.

It appears that some of the international networks are catching

up somewhat with the United States in terms of network link speed.

That is, in 1991 most international network backbones were either 9.6

Kbps or 64 Kbps, compared with the United States' 45 Mbps backbone;

in 1996, over a third of the international networks are projected to

have a 45 Mbps backbone compared with the United States projected 1

Gbps backbone.

4.3.3.3 2000 Projections Of International Network Link Speeds

The 2000 projected link speeds for the international research

networks are presented in Exhibit 4-7 and summarized in Exhibit 4-8.

The same 36 locations (i.e., nation, multi-nation, continent, or

world) used to project 1991 and 1996 link speeds are used for 2000.

As indicated in Exhibit 4-7, in 2000, backbone link speeds range

from 1.544 Mbps to 1 Gbps. Exhibit 4-8 shows that, in 2000, about

Many of the international networks continue to catch up somewhat

with the United States in terms of network link speed. In 1996, the

most advance international networks had 45 Mbps backbones, compared

with the United States' projected 1 Gbps backbone; in 2000, over a

third of the international networks are projected to have a 1 Gbps

backbone compared with the United States projected 5 Gbps backbone.

4.3.3.4 2010 Projections Of International Network Link Speeds

The 2010 projected link speeds for the international research

networks are presented in Exhibit 4-9 and summarized in Exhibit

4-10. The same 36 locations (i.e., nation, multi-nation, continent,

or world) used to project 1991, 1996 and 2000 link speeds are used

for 2010.

As indicated in Exhibit 4-9, in 2010, backbone link speeds range

from 45 Mbps to 5 Gbps. Exhibit 4-10 shows that, in 2010, about

thirty percent of the international networks are expected to have a

45 Mbps backbone, about thirty percent are expected to have a 1 Gbps

backbone, and about forty percent are projected to have a 5 Gbps

backbone.

In 2010, the most advance international networks are projected to

have a 5 Gbps backbone compared with the United States projected 25

Gbps backbone.

4.3.4 Projections Of Speeds Of U.S.-International Links

As with the projection of international network link speeds,

projections of the speeds of the United States-international links

have been developed for 1991, 1996, 2000 and 2010.

4.3.4.1 1991 Projections Of Speeds Of U.S.-Internationai Links

As indicated earlier in Exhibits 4-1 and 4-2, currently there are

77 United States-international links connecting 22 United States

cities to 48 foreign cities in 18 countries. When projecting the

1991 speeds of the United States-international links, it was assumed

that these links would be consolidated. It also was assumed that

network development in each foreign country would be sufficiently

advanced to permit effective indirect access to foreign cities no

longer (i.e., after link consolidation) directly linked to the United

States cities. The results of this consolidation and the 1991 link

speed projections are presented in Exhibit 4-11.

As indicated in Exhibit 4-11, the number of international links,

the number of United States cities, and the number of foreign cities

have been reduced significantly. The only constant is the number of

foreign countries. The number of international links has been

reduced from 77 to 20. As proposed by the CCIRN and the FEPG, there

is only one major link to each foreign country, except in the cases

of Canada and Mexico, for which there are two links because they are

neighbors of the United States. The number of United States cities

has been reduced from 22 to seven. The number of foreign cities has

been reduced from 48 to 20.

The projections of the 1991 links speeds were based on the

following: the current number and speeds of links to each foreign

country; the 1991 projected link speed of the backbone of the network

in each foreign country; and the policies proposed by various

organizations concerned with international traffic. As indicated in

Exhibit 4-11, the projected 1991 link speeds of the new 20

international links range from 9.6 Kbps to 1.544 Mbps. About 40

percent of these links are expected to operate at 1.544 Mbps, about

40 percent at 64/128 Kbps, and about 20 percent at 9.6 Kbps. As

noted earlier, the range of the link speeds of the current 77

international links is the same but the percentages of these 77 links

at each speed, are much different (i.e., 2% at 256 Kbps-l.544 Mbps,

43% at 56-64 Kbps, and 55% at 9.6-19.2 Kbps).

Thus, the consolidation of United States-international links will

make it possible to provide, in 1991, better service between the

United States and many of the foreign countries. Improved service to

some countries will not be possible yet, because of the limited

number of links to those countries (e.g., Malaysia). As neighbors of

those countries develop their networks and acquire a need to connect

to United States networks, consolidation and the resulting improved

service will be more feasible. This development of new networks in

foreign countries will be considered in Section 6.

4.3.4.2 1996 Projections Of Speeds Of U.S. International Links

When projecting the 1991 speeds of the United Statesinternational links, it was assumed that the consolidation that had

taken place in 1991 would remain the same. That is, the number of

links, the number of United States cities, and the number of foreign

cities/countries were projected to remain the same in 1996 as they

were in 1991.

It is quite possible that by 1996, two important events might

have occurred. Firstly, new international networks might have been

developed in various foreign countries, requiring new connectivity

with the United States. Secondly, continent-wide networks might have

been expanded (e.g., in Europe) permitting indirect access to foreign

countries which now are linked directly with the United States (e.g.,

Norway). Both of these possible events will be considered in Section

6, when the new IRNs are described.

The projections of the 1996 links speeds were based on factors

similar to those used for projecting 199l link speeds: the 1991

spccds of links to each forcign country; the 1996 projcctcd link

speed of the backbone of the network in each foreign country; and the

policies proposed by various organizations concerned with

international traffic. As indicated in Exhibit 4-12, the projected

1996 link speeds of the new 20 international links range from 64 Kbps

to 45 Mbps. About 55 percent of these links are expected to operate

at 45 Mbps, 30 percent at 1.544Mbps, and 15 at 64 Kbps.

4.3.4.3 2000 Projections Of Speeds Of U.S. International Links

When projecting the 2000 speeds of the United Statesinternational links, it was assumed that the consolidation that had

taken place in 1991 and 1996 would remain the same. That is, the

number of links, the number of United States cities, and the number

of foreign cities/countries were projected to remain the same in 2000

as they were in 1991 and 1996.

As discussed for 1996, it is quite possible that by 2000, two

important events might have occurred. Firstly, new international

networks might have been developed in various foreign countries,

requiring new connectivity with the United States. Secondly,

continent-wide networks might have been expanded (e.g., in Europe)

permitting indirect access to foreign countries which now are linked

directly with the United States (e.g., Norway). Again, both of these

possible events will be considered in Section 6, when the new IRNs

are described.

The projections of the 2000 links speeds were based on factors

similar to those used for projecting 1991 and 1996 link speeds: the

1996 speeds of links to each foreign country; the 2000 projected link

speed of the backbone of the network in each foreign country; and the

policies proposed by organizations concerned with international

traffic. As indicated in Exhibit 4-13, the projected 2000 link

speeds of the new 20 international links range from 1.544 Mbps to 1

Gbps. About 55 percent of these links are expected to operate at 1

Gbps, 30 percent at 45 Mbps, and 15 percent at 1.544 Mbps.

4.3.4.4 2010 Projections Of Speeds Of U.S. International Links

When projecting the 2010 speeds of the United Statesinternational links, it again was assumed that the consolidation that

had taken place in 1991, 1996 and 2000 would remain the same. That

is, the number of links, the number of United States cities, and the

number of foreign cities/countries were projected to remain the same

in 2000 as they were in 1991, 1996 and 2000.

As indicated for 1996 and 2000, it is quite possible that by

2010, two important events might have occurred. Firstly, new

international networks might have been developed in various foreign

countries, requiring new connectivity with the United States.

Secondly, continent-wide networks might have been expanded (e.g., in

Europe) permitting indirect access to foreign countries which now are

linked directly with the United States (e.g., Norway). As before,

both of these possible events will be considered in Section 6, when

the new IRNs are described.

The projections of the 2010 links speeds were based on factors

similar to those used for projecting 1991, 1996 and 2000 link

speeds: the 2000 speeds of links to each foreign country; the 2010

projected link speed of the backbone of the network in each foreign

country; and the policies proposed by various organizations concerned

with international traffic. As indicated in Exhibit 4-14, the

projected 2000 link speeds of the new 20 international links range

from 1 Gbps to 5 Gbps. About 55 percent of these links are expected

to operate at 5 Gbps, 30 percent at 1 Gbps, and 15 percent at 45

Mbps.

4.4 SUMMARY

The current and future United States international research

network traffic flows were estimated and presented in this section.

4.4.1 Current Traffic Flow

The current traffic flow was estimated by determining the

installed capacity of the international links between the United

States networks described in the previous U.S. Domestic Research

Network Study and the international networks described in Section 3.

That is, the installed capacity of the international links, along

with the link capacity of the selected international networks, was

used to develop a picture of the current international traffic flow.

There currently are 77 United States-international links that

connect 22 United States cities to 48 foreign cities in 18

countries. Over half of these links are to Europe, over half

originate from two United States cities (i.e., Greenbelt, MD and

Princeton, N J), and about half are NASA network links. The speeds of

these international links range from 9.6 Kbps to 1.544 Mbps. Over

half of the links are 19.2 Kbps or slower, and there currently is

only one 1.544 Mbps link.

As discussed in Section 3, the link speeds of the foreign

networks, to which these 77 United States=international links

connect, range from 1.2 Kbps to 1.544 Mbps. About half of these

foreign networks have link speeds of 19.2 Kbps or less, and only

about ten percent have links speeds of 1.544 Mbps or higher.

4.4.2 Future Traffic Flow

To estimate the future international traffic flow, the future

link speeds of the international networks described in Section 3 and

the future link speeds of the United States-international links were

projected. These projections were based on: CCIRN drafted policy,

FEPG proposed policy, CCIRN perspective on worldwide research network

requirements, and major factors affecting international network

requirements. These policies, perspectives and factors were

summarized in terms of the following expectations:

1. International organizations like the CCIRN will encourage

worldwide network development and coordination.

2. World events are leading to an increase in multi-nation and even

global coooerative research efforts which will require increased

connectivity.

3. Specific research in the areas of the ¢nvirQnmenL energy.

medicine and soace are demanding more advanced network functions

and new network applications.

Page 4-41
4. Network technology research and development will encourage and

facilitatenetwork development worldwide.

On the basis of these expectations, guidelines were developed for

projecting future link speeds for the international networks and for

the international links. The guidelines for projecting international

network link speeds were: all foreign countries would move toward

developing a nationwide research network; the link speeds of the

backbones of these networks would increase to speeds as high as 5

Gbps; only the backbone of these nationwide networks would be

projected; and networks that might be developed in the future would

be considered in Section 6, but not when making these projections.

The guidelines for projecting the speeds of the United Statesinternational links were: these links would be consolidated in 1991;

the speeds of these links would increase to speeds as high as 5 Gbps;

only the consolidated links would be projected; new links that might

be required in the future would be considered in Section 6, but not

when making these projections. In both instances, projections would

be developed for 1991, 1996, 2000, and 2010.

The following is a summary of the projections of international

network link speeds:

I. 1991: slightly over half of the international networks are

expected to have only a 9.6 Kbps backbone, about one-third are

expected to have a 64 Kbps backbone, and only one-tenth are

projected to have a 1.544 Mbps backbone.

2. 1996: about one-third of the international networks are expected

to have a 64 Kbps backbone, slightly less than one-third are

expected to have a 1.544 Mbps backbone, and slightly more than

one-third are projected to have a 45 Mbps backbone.

3. 2000: about one-third of the international networks are expected

to have a 1.544 Mbps backbone, slightly less than one-third are

expected to have a 45 Mbps backbone, and slightly more than

one-third are projected to have a l Gbps backbone.

4. 2010: about one-third of the international networks are expected

to have a 45 Mbps backbone, slightly less than one-third are

Page 4-42
expected to have a 1 Gbps backbone, and slightly more than

one-third are projected to have a 5 Gbps backbone.

To develop the projections of the United States-international

links, the current 77 links were consolidated. This process reduced

the number of international links, the number of United States

cities, and the number of foreign cities. The only constant was the

number of foreign countries. The number of international links was

reduced from 77 to 20. The number of United States cities was

reduced from 22 to seven. The number of foreign cities was reduced

from 48 to 20.

In addition to the guidelines noted above, the projections of the

speeds of the international links were based, each year, on the

following: the number and speeds of links to each foreign country

during the previous benchmark year; the projected link speed of the

backbone of the network in each foreign country during the same

benchmark year; and the policies proposed by various organizations

concerned with international traffic.

The following is a summary of the projections of the speeds of

the United States-international links:

1. 1991: link speeds of the new 20 international links range from

9.6 Kbps to 1.544 Mbps; about 40 percent of these links are

expected to operate at 1.544 Mbps, about 40 percent at 64/128

Kbps, and about 20 percent at 9.6 Kbps.

2. 1996: link speeds of the new 20 international links range from 64

Kbps to 45 Mbps; about 55 percent of these links are expected to

operate at 45 Mbps, 30 percent at 1.544 Mbps, and 15 at 64 Kbps.

3. 2000: link speeds of the new 20 international links range from

1.544 Mbps to 1 Gbps, about 55 percent of these links are expected

to operate at 1 Gbps, 30 percent at 45 Mbps, and 15 percent at

1.544 Mbps.

4. 2010: link speeds of the new 20 international links range from 1

Gbps to 5 Gbps; about 55 percent of these links are expected to

operate at 5 Gbps, 30 percent at I Gbps, and 15 percent at 45

Mbps.

Page 4-43
These estimates of current and future traffic flows will be used,

along with information on recent changes in United States networks

and in NREN plans, to describe new current and future IRNs in Section

6. Also to be considered in Section 6 are the impacts, on the

current and future IRNs, of the development of new international

foreign country and continent-wide networks. Such impacts likely

will include additional consolidation of United States-international

links to produce a more efficient and effective research network.

SECTION 5

UPDATE OF UNITED STATES

RESEARCH NETWORKS

5.1 OVERVIEW

5.1.1 Purpose

In this section, information collected in the earlier study

(i.e., the U.S. Domestic Research Network Study) on the United States

research networks and on the National Research and Education Network

(NREN) is updated. That is, the purpose of this section is to

describe unanticipated changes in United States networks that have

taken place, since the completion of the earlier study, and that

might have significant impacts on the current and future Integrated

Research Network (IRN) defined in the earlier study. For this

purpose, the focus is on changes related to the topologies of the

United States networks and to the plans for the NREN. This update of

the United States networks and of the NREN will be used, along with

the estimates of current and future traffic flows presented in

Section 4, to describe new current and future IRNs. This section

discusses two major topics: changes in United States research

networks, and plans for the NREN.

5.1.2 Approach

Updating the information on the United States research networks

and the NREN entailed the following activities: collecting

information from the managers of each network; collecting information

on the NREN from industry leaders; and organizing this information so

its impact on the current and future IRNs could be determined.

To collect information on the United States networks, the

Page 5-1
managers of all the networks described in the earlier study (see

Exhibit 5.1) were contacted by mail and by telephone. Each manager

was sent a copy -of the narrative description and the topology map

prepared for his network. He was asked to review this information

and to identify any major changes that should be made in either the

narrative description or the topology map. This mailing was followed

up by telephone calls until the necessary information was obtained.

The information then was organized so that the impact of the

significant changes could be assessed in Section 6.

Current information on the NREN plans was obtained by

interviewing industry leaders identified in the earlier study and by

reviewing documents describing current NREN plans. Interviews were

conducted in person (e.g., during the EDUCOM National Net'90) and

over the telephone. Documents were obtained from the various groups

and committees which are involved in the planning of the NREN. Based

on this information, the current status and future plans for the NREN

were summarized and used in Section 6 to describe the new current and

future IRNs.

5.2 CHANGES IN UNITED STATES RESEARCH NETWORKS

As noted above, the changes in the United States research

networks that are the most important for the purposes of this study

are those pertaining to the topologies of these networks. These

changes are summarized below for each network. The network summaries

are presented in the same order as the networks appear in Exhibit

5.1. When no significant changes were identified for a network, only

a statement indicating that finding is presented for the network.

5.2.1 DoD Networks

5.2.1.2 DRI

The DRI is progressing as planned with a variety of testbeds

underway. The testbed program and its relationship to the

development of the NREN are discussed below in Section 5.3 Current

Plans for the NREN.

5.2.2 NSF Networks

5.2.2.1 NSF Backbone

By the second half of 1989, the NSF backbone had 19 links

connecting its 13 major nodes or hubs, giving most nodes three T l

connections. During National Net'90, a T3 link was demonstrated. As

predicted in the earlier study , most of the NSF backbone is expected

to have T3 speeds by the end of 1991. Therefore, there were no

unexpected changes in the NSF backbone that must be considered when

describing the new current and future IRNs.

5.2.2.2 BARRNet

While there were new members (i.e., LANs) on BARRNet, there were

no unexpected changes in the BARRNct topology that must be considered

when describing the new current and future IRNs.

5.2.2.3 JvNCnet

As with BARRNet, there were new members on JvNCnet, but there

were no unexpected changes in the JvNCnet topology that must bc

considered when describing the new current and future IRNs.

5.2.2.4 MERIT

There were some new members on MERIT, but there were no

unexpected changes in the MERIT topology that must bc considercd when

describing the new current and future IRNs.

Page 5-4
5.2.2.5 MIDnet

Again, there were new members on MIDnet, but there were no

unexpected changes in the MIDnet topology that must be considered

when describing the new current and future IRNs.

5.2.2.6 NCSAnet

One of the 56 Kbps links (from Argonne Nat'l Lab to University of

Illinois at Chicago) was increased to a TI. There were no other

unexpected changes in the NCSAnet topology that must be considered

when describing the new current and future IRNs.

5.2.2.7 NorthWestNet

Several new members (i.e., LANs) joined NorthWestNet, but there

were no unexpected changes in the NorthWestNet topology that must be

considered when describing the new current and future IRNs.

5.2.2.8 NYSERNet

Like the other regionals discussed above, NYSERNet added new

members, but there were no unexpected changes in the its topology

that must be considered when describing the new current and future

IRNs.

However, an important development involving NYSERNet has taken

place. A new company, Performance Systems International, Inc. (PSI),

was created to sell access to NYSERNet. This development may mark

the beginning of the commercialization of the NREN. PSI has named

its new network PSInet which now includes NYSERNet (which serves the

New York region) and CAPNet (which serves the Washington, D.C.

area). Plans for expanding PSInet nationwide are being considered.

5.2.2.9 PSCNET

PSCNET also added new members, but there were no unexpected

Page 5-5
changes in the PSCNET topology that must be considered when

describing the new current and future IRNs.

5.2.2.10 SDSCnet

There were no unexpected changes in the SDSCnet topology that

must be considered when describing the new current and future IRNs.

5.2.2.11 SESQUINet

There were no unexpected changes in the SESQUINet topology that

must be considered when describing the new current and future IRNs.

5.2.2.12 SURAnet

Many new members (i.e., LANs) have been added to SURAnet, but as

with many of the other regionals, there were no unexpected changes in

the SDSCnet topology that must be considered when describing the new

current and future IRNs.

5.2.2.13 USAN

The site in Wisconsin has been dropped. The two sites in Mexico

are now UNAM (Mexico City) and ITESM (Atizapan de Zaragoza). All

other aspects of this network have remained the same or as

projected.

5.2.2.14 WESTNet

The University of Arizona is connected to the University of

Utah, not to the University of New Mexico as indicated in the earlier

study. Also, the network's major links have been upgraded from 56

Kbps to TI. Except for the addition of new members, all other

aspects of this network have remained the same or as projected.

Page 5-6
5.2.2.15 CERFnet

This network has been rapidly adding new members, but there were

no unexpected changes in the CERFnet topology that must be considered

when describing the new current and future IRNs.

5.2.2.16 CICNet

There were no unexpected changes in the CICNet topology that

must be considered when describing the new current and future IRNs.

5.2.2.17 Los Nettos

There were no unexpected changes in the Los Nettos topology that

must be considered when describing the new current and future IRNs.

5.2.2.18 MRNet

While MRNet has been adding new members, there were no

unexpected changes in the CERFnet topology that must be considered

when describing the new current and future IRNs.

5.2.2.19 NEARnet

NEARnet also has added members, but there were no unexpected

changes in the NEARnet topology that must be considered when

describing the new current and future IRNs.

5.2.2.20 OARnet

As with most of the other regional networks, OARnet has added

members, but there were no unexpected changes in the OARnet topology

that must be considered when describing the new current and future

IRNs.
5.2.2.21 PREPnet

There were no unexpected changes in the PREPnet topology that

must be considered when describing the new current and future IRNs.

5.2.2.22 THEnet

There were no unexpected changes in the THEnet topology that

must be considered when describing the new current and future IRNs.

5.2.2.23 NSFNET Summary

There were only a few unexpected changes in the NSFNET

topologies that must be considered when describing the new current

and future IRNs. These few changes involved the dropping or adding

of a site (e.g.,with USAN), the changing of a city-pair (e.g.,with

WestNet), or the changing of the typical link speed of the network

(e.g., WestNet). The most consistent change across all regional

networks was the addition of new members (i.e.,LANs); but this

change was anticipated and discussed in the Task Order 2 report.

5.2.3 NASA Research Networks

5.2.3.1 NSN

While new members were added to the NASA Science Network, there

wcrc no unexpected changes in the NSN topology that must be

considered when describing the new current and future IRNs.

5.2.3.2 NASCOM

While new members were added to, and some old members were

dropped from, the NASA Communications (NASCOM) Network, there wcrc no

unexpected changes in the NASCOM topology that must be considered

when describing the new current and future IRNs.

Page 5-8
5.2.3.3 NASNET

There were no unexpected changes in the Numerical Aerodynamics

Simulation Network (NASCOM) topology that must be considered when

describing the new current and future IRNs.

5.2.3.4 SPAN

There were no unexpected changes in the Space Physics Analysis

Network (SPAN) topology that must be considered when describing the

new current and future IRNs.

5.2.4 DOE Research Networks

5.2.4.1 ESNET

There were no unexpected changes in the Energy Science Network

(ESNET) topology that must be considered when describing the new

current and future IRNs.

5.2.4.2 HEPNET

There were no unexpected changes in the High Energy Physics

Network (HEPNET) topology that must be considered when describing the

new current and future IRNs.

5.2.4.3 LEP3NET

There were no unexpected changes in the LEP3NET (a Cern

Accelerator Experiment Network) topology that must be considered when

describing the new current and future IRNs.

5.2.4.4 OPMODEL

There were no unexpected changes in the OPMODEL topology that

must be considered when describing the new current and future IRNs.

Page 5-9
5.2.5 BITNET & CSNET

Effective September, 1989, BITNET and CSNET were merged under a

new organization, the Corporation for Research and Educational

Networking (CREN). CREN is a continuation of the old BITNET, Inc.,

under the new name and with revised bylaws, and it accepted

responsibility from UCAR for the CSNET network. CREN now provides

BITNET and CSNET networking services to members throughout the world.

This merger was anticipated, when developing the Task Order 2

report, and it has not caused any unexpected changes in topologies

that must be considered when describing the new current and future

IRNs.

5.2.6 Summary Of United States Research Network Changes

There have been very few unexpected changes in the United States

Research Networks, since the preparation of the Task Order 2 report,

that must be considered when describing the new current and future

IRNs. The most important changes, those involving growth of the

various networks, were anticipated. Examples of changes included:

one of the cities of a city pair was changed; a site was dropped; and

a network with slower link speeds increased its backbone link speed

from 56 Kbps to 1.544 Mbps several months earlier than anticipated.

None of these changes will have any significant effects on the

planning of the new current and future IRN.

5.3 CURRENT NREN PLANS

The current NREN plans are summarized below by presenting a

description of the NREN, an outline of the implementation of the

NREN, and a listing of recent events concerning the NREN. This

summary of current NREN plans will be used in Section 6 to help

describe the new current and future IRNs.

Page 5-10
5.3.1 Current NREN Description

The current NREN is described below in terms of its goal,

objectives, benefits, access, services, network structure, management

and financing.

5.3.1.1 Goal

The goal of the NREN, as typically presented, is to enhance

national competitiveness and productivity through a high speed, high

quality network infrastructure which supports a broad set of

applications and network services for the research and education

community.

5.3.1.2 Objectives

To accomplish this NREN goal the following objectives have been

proposed:

1. Support development of advanced United States network technology

and services.

2. Increase technology transfer among government, industry and

education.

3. Provide access to and encourage development of information

resources, instruments, and computation centers whose

characteristics make them national assets worth sharing.

4. Create a network architecture that will evolve to meet capacity,

connectivity, security, management and service requirements.

5.3.1.3 Benefits

Accomplishing the NREN goal and objectives are expected to

result in a wide range of public and private benefits, including:

1. Increased research productivity, education and technology

transfer.

2. Maintenance of United States leadership in research and

education.

Page 5-1 1
3. Improvement of United States competitiveness in world markets.

4. Acceleration of the development of commercial networks and

electronicinformation services.

5.3.1.4 Access

It has been proposed that the NREN be accessible by the entire

United States higher education, research and development community

for uses that are consistent with the NREN goal. Some have proposed

that anyone doing research, at any level, should have access.

5.3.1.5 Services

It is expected that the development of the NREN will result in

the modernization and enhancement of services available on current

networks to meet the needs of research users and to provide

connection to specialized databases and computational facilities not

currently accessible.

5.3.1.6 Network Structure

The most frequently discussed model for the NREN is a

three-level structure comprised of:

1. An interstate backbone supporting high volume network traffic

with at least one access node in every state.

2. A mid-level tier of state and regional networks providing broad

intrastate connectivity.

3. A third level composed of individual campuses and government and

industrial laboratories.

5.3.1.7 Management

A number of management structures have been proposed, ranging

from a public corporation to an industry operated venture. The

public corporation would involve a partnership among government,

industry and education. The industry operated venture would be

Page 5-12
similar to current industry efforts.

5.3.1.8 Funding

Typical funding proposals suggest a shared responsibility of

federal research sponsors, educational agencies and private sector

organizations. The major funding questions, which still exist,

concern when, how and how much the various entities should

contribute.

5.3.2 Implementation Plans

The current NREN implementation plans are described below in

terms of connectivity, R&D stages, and its testbed program.

5.3.2.1 NREN Connectivity

It is expected that the NREN will interconnect the following:

1. Educational institutions.

2. National laboratories, non-profit research institutions, and

government facilities.

3. Commercial organizations engaged in government-supported research

or collaborating in such research.

4. Unique national scientific and scholarly resources such as

supercomputer centers, major experimental facilities, databases,

and libraries.

5.3.2.2 NREN R&D Stages

As presented in the earlier study, the NREN is expected to

progress through the following three R&D stages (It is currently in

Stage 2):

Stage 1 -

Stage 2 -

Upgrade existing U.S. agency trunks to 1.544 Mbps.

Combine multi-agcncy trunks into a shared 45 Mbps trunk

Page 5-17
5.3.3.1 Federal Agency Activity

The following are examples of recent federal agency activity

having a direct impact on the NREN:

1. The FRICC issued a Program Plan for the NREN.

2. The White House OSTP published a report on the Federal High

Performance Computing Program, which incorporated the FRICC

Program Plan.

3. The White House Science Advisor voiced strong support for the

NREN.

4. The proposed federal budget for FY91 included $469 million in

budget authority for High Performance Computing (this represents

a five percent increase).

5. The FRICC was replaced by the Federal Networking Council (FNC).

5.3.3.2 Federal Legislation

Three bills are currently pending in Congress to authorize the

NREN:

1. Senate Bill 1067:

.

°

Introduced by Senator Gore in May, 1989;

creates the NREN and authorizes $390 million in funding for the

network over fiscal years 1991 through 1995.

House Bill 3131: Companion bill to Senate bill 1067; introduced

by Congressman Walgren.

Senate Bill 1976: Introduced in November 1989 on behalf of the

DOE by Senator Johnston. Provisions relating to the NREN are

parallel to those of the Gore Bill.

5.3.3.3 Network Activity

The following network activities are especially relevant to the

NREN:

1. The increase in the link speed of the NSFNET backbone from 1.544

Mbps to 45 Mbps was begun.

Page 5- I 8
2. Over 1000 networks are now connected to the NSFNET; an increase

of about 400 since mid-19$9.

3. Research in advanced networking techniques (i.e., Gbps testbeds)

continued on schedule.

5.3.3.4 Current NREN Issues

The following are the four most frequently discussed issues

related to the NREN:

1. Ubiquity: How many people have access? Who should have access?

2. Performance: What peak and aggregate rates are necessary?

3. Funding: Who should fund what portions of the NREN? When?

4. Management: What type of management should the NREN have?

Public? Private? Combination?

5.3.4 Summary Of Current NREN Plans

Since the completion of the earlier U.S. Domestic Research

Network Study, NREN plans have become more clearly delineated. The

NREN, in terms of its goal, objectives, benefits, access, services,

network structure, management and funding, has been articulated. The

NREN implementation plans are on schedule. Connectivity expectations

have been well specified, the NREN is in the second of three R&D

stages, and the NREN testbed program is equally well planned.

Finally, a number of recent federal agency, legislative and network

development activities are directly impacting the NREN and are

helping to clarify major NREN issues related to ubiquity,

performance, funding and management.

5.4 SUMMARY OF UPDATE OF U.S. RESEARCH NETWORKS

There have been very few unexpected changes in the United States

Research Networks, since the completion of the earlier study, that

must be considered when describing the new current and future IRNs.

Page 5-19
In fact, it is expected that none of these unexpected changes will

have any significant effects on the planning of the new current and

future IRN. The current NREN plans are progressing smoothly) but not

without a lot of effort from those involved in its development.

While no groups have indicated opposition to the development of an

NREN, a number of major issues remain unresolved, and funding for the

network is only increasing very slowly because of the tremendous

competition for funds. In summary) the status of the NREN has

improved significantly during the last year, but much work remains to

be done.

Page 5-20
SECTION 6

CURRENT AND FUTURE

INTEGRATED RESEARCH NETWORKS

6.1 OVERVIEW

6.1.1 Purpose

In this Section, new current and future Integrated Research

Networks (IRNs) are described. That is, the results of the current

study, presented in Sections 2 5, are used to modify the original

IRNs developed in previous U.S. Domestic Research Network Study. The

findings presented in Sections 2 and 3, which include descriptions of

the international research network community and major research

networks outside of the United States, provide a worldwide

perspective for developing the new IRNs. Estimates of the current

and future international traffic flows presented in Section 4 and the

update of the United States Research networks and the NREN plans

discussed in Section 5 are used, along with the current and future

IRNs described in the previous domestic study, to develop new current

and future IRNs. These new IRNs, while still focused on the United

States, now include international as well as domestic research

network requirements. This section includes three major topics:

impact of unexpected changes in United States networks, the current

IRN, and the future IRNs.

6.1.2 Approach

To update the IRNs, the completion of three activities were

required:

1. The assessment of the impact of unanticipated changes in the

United States research networks and in the NREN plans;

2. The incorporation of the current international research

Page 6-1
network traffic flow in the current IRN; and

3. The incorporation of the future international research network

traffic flows in the future IRNs.

To determine the impact of the unanticipated changes in United

States research networks on the current and future IRNs, each change

was reviewed to determine whether or not it would have an impact on

the original topology maps developed for the current and future

IRNs. That is, if the change required a modification of the major

access points, the connectivity, or the link speeds of any of the IRN

topology maps, these modifications were made.

In a similar manner, the current NREN plans were reviewed to

determine if any unanticipated changes in these plans required

modifications in the original projections of future research network

requirements. Since this study does not focus on the political and

social implications of the NREN, but on its technical network

requirements, changes in the planned NREN technical network

requirements were given the most attention.

To incorporate the current estimate of international research

network traffic in the current IRN, the United States-lnternational

links and the international network link speeds were added to the

information on the original current IRN topology map. The

international links were not consolidated, because currently they are

not consolidated. The composite diagram now depicts the new current

IRN, i.e., it is the new IRN topology map.

In a similar manner, the estimates of the future international

research network traffic flow were incorporated in the future IRNs.

That is, the information depicted on the original future IRN topology

maps was supplemented with the future link speeds of the

international research networks and the descriptions of the future

United States-international links. The information was presented in

a single composite diagram for each future benchmark year. As noted

in Section 4, the same future benchmark years (i.e., 1991, 1996, 2000

Page 6-2
and 2010)usedin the earlier study were usedagain for this study.

Also, as noted in Section 4, the United States-international

links initially were consolidated to give each United States city

only one link to any foreign country. When developing the new future

IRNs, an additional consolidation of links was made based on an

understanding of network requirements between the United States and

each foreign country. When making this additional consolidation, it

was assumed that continent-wide networks would be developing in

selected parts of the world (e.g., Europe), and that the United

States would have several links to these continent-wide networks and

would not need direct access to every major country. This resulted

in a maximum of one United States-international link to each foreign

country and only indirect links to some countries.

While it is possible that some researchers in the United States

may desire to have dedicated links to some foreign countries for

special projects, such dedicated links are not reflected in the new

future IRN topologies. It is believed that these requirements are

related to security and redundancy and will have minimal impact on

traffic projections. Four new future topology maps were developed to

depict the results of these analyses of the future IRNs.

6.2 IMPACT OF UNEXPECTED CHANGES IN UNITED STATES NETWORKS

The impact of unexpected changes in the United States networks

on the current and future IRNs are discussed under two topics:

changes pertaining to the specific research networks and changes

pertaining to NREN plans.

6.2.1 Unexpected Changes In Research Networks

As noted earlier in Section 5, there have been very few

unexpected changes in the United States Research Networks, since the

completion of the earlier domestic study, that must be considered

Page 6-3
whcn dcscribing thc ncw current and futurc IRNs. Thc most important

changes, those involving growth of the various networks, had been

anticipated when completing the earlier study. The reasons for this

lack of unexpected change include the following:

1. The earlier study was completed only about six months ago.

2. Input was obtained from experts at all levcls of the industry, so

the composite of their insights is still valid.

3. The earlier study required, just as the currcnt study does, the

anticipation of future events and trends and the reflection of

their impact on the IRNs; consequently all of the more important

changes were expected and incorporated in the original results.

However, each unexpected change in the specific research

networks was reviewed and analyzed. Unexpected changcs in specific

research networks included: one of the cities of a city pair was

changed; a site was dropped; and a network with slower link speeds

increased its backbone link speed from 56 Kbps to 1.544 Mbps several

months earlier than anticipated. Based on this review and analysis,

it was concluded that none of these changes will have any significant

effects on the planning of the new current and future IRNs. That is,

these specific network changes were not sufficiently significant to

require changes in the original current and future IRN topology and

capacity maps which reflected domestic research network requirements.

6.2.2 Unexpected Changes In NREN Plans

In Section 5, the current NREN plans were summarized by

presenting a current description of the NREN, an outline of the

implementation of the NREN, and a listing of recent events concerning

the NREN. The current NREN was described in terms of its goal,

objectives, benefits, access, services, network structure, management

and financing. Implementation plans were described in terms of

connectivity, R&D stages, and its testbed program. Recent events

were grouped under the following headings: federal agency activity,

federal legislation, network activity, and NREN issues. These NREN

plans and related events then were analyzed to determine whether

Page 6-4
significant unexpectedchangeshad beenmadein NREN plans.

Since the completion of the earlier study, NREN plans have

become more clearly delineated, but this clarification has not

resulted in any unanticipated changes in the NREN. The description

of the NREN, in terms of its goal, objectives, benefits, access,

services, network structure, management and funding, now has been

articulated. While this additional detail concerning NREN plans is

useful in providing a perspective for developing the new current and

future IRNs, this detail has not affected the original current and

future IRN topology maps.

The NREN implementation is on schedule, as projected in the

earlier study. All major interest groups are having an impact on the

planning for the NREN. The NREN implementation is, as expected at

the end of the earlier study, in the second of three R&D stages. The

NREN testbed program is being implemented, perhaps slightly faster

than anticipated.

Finally, a number of recent federal agency, legislative and

network development activities are directly affecting the NREN and

are helping to clarify major NREN issues related to ubiquity,

performance, funding and management. Again, these activities were

anticipated. Activities by the FRICC (replaced by the FNC), the

White House OSTP, and the United States Congress suggest that the

NREN perspective presented in the earlier study was not too

optimistic. Similarly, network activity, in terms of improving

ubiquity and performance, indicates that the IRN topology maps

presented in the earlier study appropriately reflect expected

progress.

6.2.3 Summary Of Impacts Of Unexpected Changes

The evolution of the United States research networks and of the

NREN plans have not affected the original topology and capacity maps,

Page 6-5
developed in the earlier study for the current and future IRNs. The

original topology maps can be used, as they were presented in the

earlier study, along with information on the networks outside of the

United States and on the United States-international links, to

develop the new current and future iRNs. Hence, changes will be made

in these original topology maps only if the information on the

international networks and the United States-international links

indicates changes are necessary.

6.3 THE NEW CURRENT IRN

The new current IRN reflects international, as well as domestic,

research network requirements. It was developed, as previously

noted, using the original current IRN topology map (see Exhibit 6-I),

the current link speeds of the international research networks (see

Exhibit 6-2), and the United States-international links (see Exhibit

6-3). Exhibit 6-1 was presented initially in the earlier study, and

Exhibits 6-2 and 6-3 were presented previously in Section 4.

The new current IRN topology map is presented in Exhibit 6-4.

The information in the box in the center of this exhibit shows the

major access points and the TI connectivity of the current IRN

developed in the earlier study. As noted above in Section 6.2, the

original current IRN (see Exhibit 6-1) adequately reflects the

updated domestic network requirements.

The boxes surrounding the center box in Exhibit 6-4 include

information, taken from Exhibit 6-2, on each of the six major areas

of the world discussed in Sections 2 and 3: Canada/Mexico, Europe,

Central/South America, AustraliaPacific and Asia. For each of these

major areas, the range of the typical link speeds of the backbones of

the research networks in the countries in the area is indicated. For

example, in Europe the typical backbone links speeds of the research

networks in the European countries is 9.6 Kbps through 64 Kbps.

The lines connecting the center box with the surrounding boxes

show actual United States-international links. That is, these lines

depict actual links between United States cities and cities in other

parts of the world. As previously noted, these are not consolidated

links. The numbers in the circles by each line indicate the number

of links that the line represents. For example, the lines connecting

the United States to Europe shows that there are twenty-three 9.6

Kbps link, twenty 64 Kbps links and one 1.544 Mbps link connecting

the United States to Europe. This information was taken from Exhibit

6.3.

As indicated in Exhibit 6-4, there are some 76 links connecting

the United States research networks to research networks in countries

around the world. These links range in speeds from 9.6 Kbps to 1.544

Mbps, and they connect a TI backbone in the United States to research

networks around the world, and that have link speeds ranging from 1.2

Kbps to 64 Kbps. Currently, there are no direct United States links

to Africa.

A perusal of Exhibits 6-2 to 6-4 shows that the current United

States research network backbone link speed is higher than the

backbone link speed of the various networks in other parts of the

world. Also, note that the backbone link speed is higher than the

typical link speed of links connecting the United States to other

parts of the world. It is, therefore, apparent that the original

current IRN topology and capacity map does not have to be altered to

incorporate current international network requirements. In view of

the number of duplicate United States-International links, it is also

apparent that consolidating the international links would save money

just as integrating the networks in the United States would save

money.

6.4 THE NEW FUTURE IRNS

As noted earlier, the new future IRNs reflect anticipated growth

Page 6-15
in international as well as domestic research network requirements.

A new future IRN was developed for each of the benchmark years (i.e.,

1991, 1996, 2000, and 2010) used in the earlier study. Future IRNs

were developed using a procedure similar to that used to develop the

new current IRN. Each new future IRN is discussed below.

6.4.1 The New 1991 IRN

The new 1991 IRN was developed using the original 1991 IRN

topology map (see Exhibit 6-5), the 1991 link speeds of the

international research networks (see Exhibit 6-6), and the 1991

United States-international links (see Exhibit 6-7). Exhibit 6-5 is

taken from the earlier domestic study, and Exhibits 6-6 and 6-7 were

presented previously in Section 4.

The new 1991 IRN topology and capacity map is presented in

Exhibit 6-8. The information in the box in the center of this

exhibit shows the major access points and the T3/TI connectivity of

the 1991 IRN developed in the earlier study. As noted above in

Section 6.2, the original 1991 IRN (see Exhibit 6-5) adequately

reflects the updated domestic network requirements.

As with the new current IRN, the boxes surrounding the center

box in Exhibit 6-8 includes information (taken from Exhibit 6-6) on

each of the six major areas of the world discussed in Sections 2 and

3: Canada/Mexico, Europe, Africa, Central/South America, Australia/

Pacific and Asia. Again, for each of these major areas, the range of

the typical link speeds of the backbones of the research networks in

the countries in the area is indicated. For example, in Europe the

typical backbone links speeds of the research networks in the

European countries is projected to be in, 1991, 9.6 Kbps through

1.544 Mbps.

Note that in Exhibit 6-8, the lines connecting the center box

with the surrounding boxes show consolidated, not actual (as they did

in the previously presented exhibit depicting the new current IRN),

United States-international links. As notcd in Scetion 4 and in the

overview for this section, the United States-international links

initially were consolidated to give each United States city only one

link to any foreign country (see Exhibit 6-7).

When developing the new 1991 IRN, an additional consolidation of

links was made based on an understanding of 1991 network requirements

between the United States and the major areas of the world (e.g.,

Europe). When making this additional consolidation, it also was

assumed that continent-wide networks would be developing in selected

parts of the world (e.g., Europe), and that the United States would

have several links to these continent-wide networks and, therefore,

would not need direct access to every major country. This resulted

in a maximum of one United States-international link to each foreign

country, and only indirect links to some countries.

While it is possible that the United States' researchers may

require more than one link to some foreign countries, or may require

separate links for special projects, these requirements were not

reflected in the new 1991 or other new future IRN topologies. It is

believed that these requirements would be based more on needs related

to security and redundancy than on capacity needs. Thus, the link

lines in Exhibit 6-8 depict what are expected to be consolidated

United States' international link requirements in 1991. For example,

Exhibit 6.8 shows three 1.544 Mbps links between the United States

and Europe, indicating that three such links will meet expected

United States link connectivity requirements with Europe in 1991.

As indicated in Exhibit 6-8, there are only 10 links connecting

the United States research networks to research networks in countries

around the world. These links are all 1.544 Mbps links except for

the two links to Mexico and Central/South America which arc 128 Kbps

links and one of the two links to Asia which is a 9.6 Kbps link. The

ten links connect a T3/TI backbone in the United States to research

networks that are located around the world and that have link speeds

ranging from 9.6 Kbps to 1.544 Mbps.

Page 6-22
Note that the 1991 United States research network backbone link

speed is still higher than the backbone link speed of the various

networks in other parts of the world. Also, note ,'hat it is higher

than the typical projected link speed of links connecting the United

States to other parts of the world. It is apparent, therefore, that

the original 1991 topology and capacity map does not have to be

altered to incorporate international research network requirements.

However, continual improvements are needed in the United

States-international links.

6.4.2 The New 1996 IRN

The new 1996 IRN was developed using the original 1996 IRN

topology map (see Exhibit 6-9), the projected 1996 link speeds of the

international research networks (see Exhibit 6-10), and the 1996

United States-international links (see Exhibit 6-11). Exhibit 6-9

was presented initially in the earlier domestic study, and Exhibits

6-10 and 6-11 were presented previously in Section 4.

The new 1996 IRN topology map is presented in Exhibit 6-12. The

information in the box in the center of this exhibit shows the major

access points and the connectivity, with link speeds ranging from 45

Mbps to 1 Gbps, of the 1996 IRN developed in the earlier study (see

Exhibit 6-9). As noted above in Section 6.2, the original 1996 IRN

(see Exhibit 6-9) adequately reflects the updated domestic network

requirements.

As with the new 1991 IRN, the boxes surrounding the center box

in Exhibit 6-12, showing the new 1996 IRN, include information (from

Exhibit 6-10) on each of the six areas of the world discussed in

Sections 2-3: Canada/Mexico, Europe, Africa, Central/South America,

Australia /Pacific and Asia. Again, for each of these areas, the

range of the typical link speeds of the backbones of the research

networks in the countries in the area is noted. For example, in

Europe the typical backbone links speeds of the research networks in

European countries is projected to be in, 1996, 64 Kbps to 45 Mbps.

In Exhibit 6.12, as in Exhibit 6-8 showing the new 1991 IRN

topology, the lines connecting the center box with the surrounding

boxes represent consolidated, not actual United States-international

links (see Exhibits 6-11). As with 1991, an additional consolidation

of links was made based on an understanding of 1996 network

connectivity requirements between the United States and each of the

major areas of the world (e.g., Europe). This understanding is built

upon the 1991 projected link speeds of the United

States-international links (see Exhibit 6-8).

As indicated in Exhibit 6-12, there are (as there were for 1991)

only 10 links connecting the United States research networks to

research networks in countries around the world. These links in 1996

are all 45 Mbps links except for two links to Mexico and Central and

South America and one to Asia which are 1.544 Mbps links. The ten

links connect a backbone, ranging in link speeds from 45 Mbps to 1

Gbps, in the United States to research networks that are around the

world that have link speeds ranging from 9.6 Kbps to 45 Mbps.

Again, note that the 1996 United States research network

backbone link speed is still higher than the backbone link speed of

the various networks in other parts of the world. It is also higher

than the typical link speed of links connecting the United States to

other parts of the world. Therefore, just as for 1991, it is

apparent that the original 1996 topology and capacity map does not

have to be altered to incorporate international research network

requirements. However, continual improvements are needed in the

United States-international links.

6.4.3 The New 2000 IRN

The new 2000 IRN was developed using the original 2000 IRN

topology map (see Exhibit 6-13), the projected year 2000 link speeds

of the international research networks (see Exhibit 6-14), and the

year 2000 United States-international links (see Exhibit 6-15).

Exhibit 6-13 was prcscntcd initially in the carlJcr study, and

Exhibits 6-14 and 6-15 were presented previously in Section 4.

The new 2000 IRN topology map is prescnted in Exhibit 6-16. The

information in the box in the center of this exhibit shows the major

access points and the connectivity, link speeds ranging from 274 Mbps

to 5 Gbps, of the 2000 IRN developed in the earlier domestic study.

As noted above in Section 6.2, the original 2000 IRN (see Exhibit

6-13) adequately reflects the updated domestic network requirements.

As with the new 1996 IRN, the boxes surrounding the center box

in Exhibit 6-16, showing the new 2000 IRN, include information (taken

from Exhibit 6-14) on each of the six major areas of the world

discussed in Sections 2 and 3: Canada/Mexico, Europe, Africa,

Central/South America, Australia/Pacific and Asia. Again, for each

of these major areas, the range of the typical link speeds of the

backbones of the research networks in the countries in the area is

indicated. For example, in Europe the typical backbone links speeds

of the research networks in the European countries is projected to be

45 Mbps through 1 Gbps by the year 2000.

In Exhibit 6-16, as in Exhibit 6-12 showing the new 1996 IRN

in thc United States to research networks around the world that have

link speeds ranging from 9.6 Kbps to 1 Gbps.

Again, note that the year 2000 United States research network

backbone link speed is still higher than the backbone link speed of

the various networks in other parts of the world. Also, it is higher

than the typical link speed of links connecting the United States to

other parts of the world. Therefore, as before for 1996, it is

apparent that the original 2000 topology and capacity map does not

requirements. However, continual improvements in terms of link

speeds are needed in the United States-international links.

6.4.3 The New 2010 IRN

The new 2010 IRN was developed using the original 2010 IRN

topology map (see Exhibit 6-17), the projected 2010 link speeds of

the international research networks (see Exhibit 6-18), and the 2010

United States-international links (see Exhibit 6-19). Exhibit 6-17

was presented initially in the earlier domestic study, and Exhibits

6-18 and 6-19 were presented previously in Section 4.

The new 2010 IRN topology map is presented in Exhibit 6-20. The

information in the box in the center of this exhibit shows the major

access points and the connectivity, with link speeds ranging from 1

major areas, the range of the typical link spccds of the backboncs of

the research networks in the countries in the area is indicated. For

example, in Europe the typical backbone links speeds of the research

networks in the European countries is projected to be in, 2010, 45

Mbps through 5 Gbps.

In Exhibit 6-20, as in Exhibit 6-16 showing the new 2000 IRN

topology, the lines connecting the center box with the surrounding

boxes show consolidated, not actual United States-international links

(see Exhibits 6-19). As for 2000, an additional consolidation of

links was made based on an understanding of 2010 network connectivity

requirements between the United States and each of the major areas of

the world (e.g., Europe). This understanding included the year 2000

projected link speeds of the United States-international links (see

Exhibit 6-16).

As indicated in Exhibit 6-20, there are (as there were for 2000)

only 10 links connecting the United States research networks to

research networks in countries around the world. These links in 2010

are all 5 Gbps links except for the two links to Mexico and Central

and South America and one to Asia which are 1 Gbps links. The ten

links connect a backbone, ranging in link speeds from 1 Gbps to 25

Gbps, in the United States to research networks around the world that

have link speeds ranging from 64 Kbps to 5 Gbps.

Again, the 2010 United States research network has a backbone

link speed that is still higher than the backbone link speed of the

various networks in other parts of the world. Also, it is higher

than the typical link speed of links connecting the United States to

other parts of the world. Therefore, as was the case with year 2000,

it is apparent that the original 2010 topology map does not have to

be altered to incorporate international research network

requirements. However, as was the case for each of the previous

benchmark years, continual improvements and consolidation are needed

in the United States-international links to make certain that

6.5 SUMMARY OF NEW CURRENT & FUTURE IRNS

The new current and future IRNs were described in this section.

The results of the current study, presented in Sections 2-5, were

used to modify the original IRNs developed in the previous U.S.

Domestic Research Network Study. First, the impact, on the current

and future IRNs, of unexpected changes in the United States research

networks and in the NREN plans was assessed and summarized. Then,

the current international research network traffic flow was

incorporated in the projection of the new current IRN. Lastly, and

in a similar manner, the future international research network

traffic flow was incorporated in the descriptions of the new future

IRNs. The results of these efforts are briefly summarized below.

6.5.1 Summary of Update

A review of the update of the United States research networks

and the NREN plans suggested that the original topology maps,

developed in the earlier study for the current and future IRNs, still

reflect expected domestic research network requirements. Therefore,

it was concluded that these original topology maps could be used,

along with information on the networks outside of the United States

and on the United States-international links, to develop the new

current and future IRNs.

6.5.2 The New Current IRN

The incorporation of the current international research network

traffic flow in the development of the new current IRN, resulted in

no change to the original current IRN domestic topology map, but

suggested a need to consolidate and improve the performance of United

States-international links. Currently, there are some 77 links

connecting the United States research networks to research networks

in countries around the world. These links range in speed from 9.6

Kbps to 1.544 Mbps, and they connect a TI backbone in the United

States to research networks around the world that have link speeds

Page 6-43
ranging from 1.2 Kbps to 64 Kbps.

United States links to Africa.

Currently, there are no direct

Thus, the current domestic United States integrated research

network has a backbone link speed that is higher than the backbone

link speed of the various networks in other parts of the world.

Also, it is higher than the typical link speed of links connecting

the United States to other parts of the world. Therefore, it was

concluded that the original current IRN topology map did not have to

be altered to incorporate current international network

requirements. Because there are a large number of international

links, it was suggested that consolidating the international links

would save money just as integrating the networks in the United

States would save money.

In summary, the new current IRN topology map includes the

following: the original current domestic topology map developed in

the earlier study; the 77 international links to six major areas of

the world; and the range of the typical link speeds of the backbones

of the research networks in the countries in the six major areas.

Please see Exhibit 6-4, page 6-14.

6.5.3 The New Future IRNs

The incorporation of the future international research network

traffic flows in the new future IRNs resulted in no changes to the

original future IRN domestic topology maps. But, as was the case

with the new current IRN, this incorporation suggested a need to

consolidate and improve the performance of United Statesinternational links for each benchmark year. The four new future

IRNs are briefly described below.

6.5.3.1 The New 1991 IRN

A Consolidation of the United States-international links in 1991

resulted in only 10 links connecting the United States research

Page 6-44
networks to research networks in countrics around the world. In

1991, these links are all projected to be 1.544 Mbps links except for

the two links to Mexico and Central/South America which are expected

to be 128 Kbps links and one of the two links to Asia which is

expected to be a 9.6 Kbps link. The ten links conncct a T3/TI

backbone in the United Statcs to research networks around the world

that have link speeds ranging from 9.6 Kbps to 1.544 Mbps,

Thus, the 1991 United States research network has a backbone

link speed that is still higher than the backbone link speed of the

various networks in other parts of the world. Also, it is higher

than the typical link speed of projected links for connecting the

United States to other parts of the world. It was therefore concluded

that the original 1991 topology map does not have to be altered to

incorporate international research network requirements. However, it

was also noted that continual improvements are needed in the United

States-international links to make certain the United States research

networks have adequate connectivity with research networks around the

world. These improvements were indicated by the increase, noted

above, in the speeds of the United States-international links.

In summary, the new 1991 IRN topology map includes the

following: the original 1991 domestic topology map developed in the

earlier study; the 10 1991 consolidated international links to six

major areas of the world; and the range of the typical 1991 link

speeds of the backbones of the research networks in the countries in

the six major areas. Please see Exhibit 6-8, page 6-21.

6.5.3.2 The New 1996 IRN

In 1996, only 10 links are projected (the same as projected for

1991) for connecting the United States research networks to research

networks in countries around the world. These links in 1996 are all

projected to be 45 Mbps links except for two links to Mexico and

Central/South America and one to Asia which are each expected to be

Page 6-45
1.544 Mbps links. The ten links connect a backbone, ranging in link

speeds from 45 Mbps to I Gbps, in the United States to research

networks around the world that have link speeds ranging from 9.6 Kbps

to 45 Mbps.

Thus, the 1996 United States research network has a backbone

link speed that is still higher than the backbone link speed of the

various networks in other parts of the world. Also, it is higher

than the typical link speed of links connecting the United States to

other parts of the world. Therefore, as was the case for 1991, it

was concluded that the original 1996 topology map does not have to be

altered to incorporate international research network requirements.

Improvements in United States-international links were indicated by

the increase, noted above, in the speeds of the United Statesinternational links.

In summary, the new 1996 IRN topology map includes the

following: the original 1996 domestic topology map; the 10 1996

consolidated international links to six major areas of the world; and

the range of the typical 1996 link speeds of the backbones of the

research networks in the countries in the six major areas. Please

see Exhibit 6-12, page 6-28.

6.5.3.3 The New 2000 IRN

In the year 2000, the same 10 links are projected for connecting

the United States research networks to research networks in countries

around the world. However, these links in the year 2000 are all

projected to be 1 Gbps links except for two links to Mexico and

Central/South America and one to Asia which are each expected to be

45 Mbps links. The ten links connect a backbone, ranging in link

speeds from 274 Mbps to 5 Gbps,'in the United States to research

networks around the world that have link speeds ranging from 9.6 Kbps

to I Gbps.

Thus, the 2000 United States research network has a backbone

Page 6-46
link speed that is still higher than the backbone link speed of the

various networks in other parts of the world. Also, it is higher

than the typical link speed of links connecting the United States to

other parts of the world. Therefore, as was the case for 1996, it

was concluded that the original 2000 topology map does not have to be

altered to incorporate international research network requirements.

Continual improvements are needed in the United States-international

links to make certain the United States research networks have

adequate connectivity with research networks around the world. These

improvements were indicated by the increase, noted above, in the

speeds of the United States-international links.

In summary, the new year 2000 IRN topology map includes the

following: the original year 2000 domestic topology map developed in

the earlier domestic study; the 10 consolidated international links

to six major areas of the world; and the range of the typical year

2000 link speeds of the backbones of the research networks in the

countries in the six major areas. Please see Exhibit 6-16, page

6-35.

6.5.3.4 The New 2010 IRN

In year 2010, the same 10 links are projected for connecting the

United States research networks to research networks in countries

around the world. As before, these links are expected to be

operating at higher speeds. In the year 2010, they are all projected

to be 5 Gbps links except for two links to Mexico and Central/South

America and one to Asia which are each expected to be 1 Gbps links.

The ten links connect, in the year 2010, a backbone, ranging in link

speeds from 1 Gbps to 25 Gbps, in the United States to research

networks around the world that have link speeds ranging from 64 Kbps

to 5 Gbps.

Hence, the year 2010 United States research network has a

backbone link speed that is still higher than the backbone link speed

of the various networks in other parts of the world. Also, it is

Page 6-47
higher than the typical link speed of links connecting the United

States to other parts of the world. Therefore, as was the case for

year 2000, it was concluded that the original year 2010 topology map

does not have to be altered to incorporate international research

network requirements. Again, it was also suggested that continual

improvements are needed in the United States-international links to

make certain the United States research networks have adequate

connectivity with research networks around the world. And again,

these improvements were indicated by the increase, noted above, in

the speeds of the United States- international links.

In summary, the new year 2010 IRN topology map includes the

following: the original year 2010 domestic topology map developed in

the earlier domestic study; the 10 consolidated international links

to six major areas of the world; and the range of the typical year

2010 link speeds of the backbones of the research networks in the

countries in the six major areas. Please see Exhibit 6-20, page

6-41.
