Demonstration af sammenkobling via lysledernet 
Sammendrag af resultaterne 
Europa-Parlamentet tog i 1992 initiativ til at fremme demonstration af lyslederkommunikation 
i EF gennem forsøg med sammenkobling af bredbåndsteknologi, f.eks. "bredbånds-øer" og 
supercomputercentre i forskellige medlemsstater. Dette initiativ var baseret på allerede 
igangsat R&D-arbejde inden for det Tredje Rammeprogram for Fællesskabets Forskning og 
Teknologi Udvikling ( 1990-1994). 
Initiativet har banet vejen for integreret bredbåndskommunikation via transeuropæiske net 
(Trans-European Networks, Integrated Broadband Communications - TEN-IBC), idet det er 
komplementært til det betydelige arbejde, der allerede er udrettet i medlemsstaterne og under 
EU's FTU-programmer. 
Der er i alle de europæiske lande opstået bredbåndsøer, enten gennem nationale initiativer eller 
under RACE-programmet0, som har skabt en større europæisk samarbejdsplatform, der kan 
føre frem til DBC. De har i høj grad medvirket til udvikling af avanceret tele­
kommunikationsudstyr, -tjenester og -applikationer, såsom højhastighedscentraler og 
-transmissionssystemer. De fleste bredbåndsøer er resultatet af en samlet indsats fra forskning, 
industri og netoperatører. 
Til gennemførelse af initiativet udsendte EF-Kommissionen en indkaldelse af interesse­
tilkendegivelser2^ som var rettet til alle centre med ekspertise i supercomputere og 
højhastighedskommunikation. Resultatet blev fire projekter0 af 12 måneders varighed, som 
omfattede bredbåndstjenester, bl a multimedia og samarbejde mellem flere parter. EU har kun 
ydet finansiel støtte til en del af de driftsomkostninger, der påløb i medlemsstaterne i 
forbindelse med samarbejdet, dvs. kommunikationsafgifter og specialudstyr, inden for det 
budget, der var til rådighed til foranstaltningen (4 mio. ECU). 
Projekterne var følgende: 
Isabel, som forbandt to bredbåndsøer i Spanien og Portugal, 
Tironet, som forbandt bredbåndsøer i Nordirland og Irland, 
Betel, som skulle forbinde lokaliteter i Frankrig og Schweiz og 
HPC-Vision, som forbandt lokaliteter i Frankrig og Tyskland. 
Projekterne blev afviklet i 1993. I det tekniske bilag er der nærmere oplysninger om 
projekterne. Efter afslutningen blev projekterne evalueret af uvildige auditorer. De erklærede, 
at resultatet var en interessant demonstration af væsentlig betydning, navnlig når det tages i 
betragtning, at der kun var et begrænset budget og tidsrum til rådighed. 
Da projekterne først og fremmest omhandlede problemer ved indbyrdes sammenkobling, blev 
projektarbejdet koordineret med RACE-projekter, og der blev udvekslet tekniske oplysninger 
om de problemer, der opstod, og om, hvordan de blev løst. Desuden leverede projekterne 
RACE: Forskning og udvikling inden for avanceret kommunikationsteknologi i Europa.

input til nogle af de fælles RACE-funktionsspecifikationer. Da projekterne var koncentreret 
om sammenkobling af bredbåndsøer inden for et forholdsvis kort tidsrum, måtte de i vid 
udstrækning bygge på resultater fra andre programmer og initiativer. Især skal nævnes: 
• Bredbåndsøer, såsom RIA (i Portugal) og RECIBA (i Spanien), der er udviklet af 
netoperatørerne, delvis med støtte fra RACE-projekter. 
• Bredbåndsapplikationer, f.eks. ESPRIT-projektet VIMP. 
• Forsøgsmæssige pilotprojekter, såsom RACE-projektet TIM og DELTA-projektet 
EAST. 
• Eksisterende net, såsom et MAN-net i Dublin og STAR-nettet4) i Belfast. 
• Eksisterende produkter og prototyper, f.eks. højhastighedscentraler (til ATM og 
rutning). 
Initiativet har bidraget til udvikling af en teleinfrastruktur og medvirket til at skabe grundlaget 
for at fremme og udvikle bredbåndskommunikation, idet operatører, brugere og producenter 
har kunnet benytte bredbåndsplatformene til afprøvning under virkelige forhold. Eksempelvis 
er der under projektet for første gang tilbudt tværnationale ATM-baserede tjenester, der bliver 
relevante for udviklingen af den kommende europæiske infrastruktur. 
Projektet har på forsøgsbasis implementeret et bredt udsnit af eksisterende eller tilpassede 
bredbåndsapplikationer. Disse applikationer vil måske i en nær fremtid danne grundlag for 
udbud af bredbåndskommunikation til slutbrugerne, f.eks. 
• Videokonference 
• Audio/video-posttjeneste 
• Elektronisk konferencetavle 
• Deling af databehandlingsopgaver mellem supercomputersystemer 
• Fjernadgang til supercomputere 
•'• Visionsbaseret on-line inspektion af fremstillede komponenter 
• Kooperativt arbejde 
• Robotapplikationer 
• Multimediekonferencer ved skrivebordet 
• Fjernundervisning af klasser, der er spredt over geografisk adskilte lokaliteter. 
Initiativet har givet brugerne lejlighed til at eksperimentere med en lang række 
bredbåndsapplikationer fra forskellige organisationer. De har på denne måde hurtigt faet 
indblik i, hvilke fordele EBC-applikationer kan give dem, og derved vil EBC blive efterspurgt. 
Operatørerne af de offentlige net har samarbejdet om løsning af brugerspecificerede 
applikationer, hvilket har givet dem større kendskab til, hvilke muligheder der ligger i lignende 
bredbåndsapplikationer. De har desuden fået større indsigt i tekniske problemer i forbindelse 
med distribuerede bredbåndsapplikationer over forbindelser med stor båndbredde, f.eks. 
fastlæggelse af faktureringsregler for ATM-tjenester. Feedback fra brugerne har haft direkte 
værdi for netoperatørernes fremtidige udvikling, mens dens indflydelse på markedet i Europa 
er gået via integration af netoperatørernes erfaringer i deres eget udviklingsarbejde. 
Projektresultaterne kan således - rigtigt udnyttet - være stærkt medvirkende til at øge 
sammenholdet og konkurrenceevnen i Europa. 
Særlig EF-foranslaltning til fremme af regionaludvikling; STAR-programmets målsætning var at forbedre 
teleinfrastrukturen, så den kan rumme avancerede teletjenester. 
- 3 -
Producenter af krydskonnektorer, rutningsenheder og andet terminaludstyr har haft mulighed 
for at afprøve deres udstyr under virkelige forhold. Derudover har de samarbejdet med 
operatørerne om at definere, hvilke tjenestekvalitetsparametre der er relevante for 
bredbåndsfaciliteter. 
Med disse resultater som grundlag vil de fleste projekter blive videreført, idet de stiller deres 
infrastruktur til rådighed for forskningsprojekter under RACE-programmet og TEN-IBC-
initiativet. Derved kan der bygges videre på den ekspertise, der er skabt gennem 
eksperimenterne med bredbåndskommunikation på tværs i Europa. De tilbyder samtidig en 
platform for forsøg under virkelige forhold, hvilket er centralt for løsning af problemerne med 
generel indførelse af bredbåndsapplikationer. De undersøger i øjeblikket mulighederne for at 
medvirke i den generelle opgave, det er at forbinde de nationale ACTS-værter5) med hinanden.

EXECUTIVE SUMMARY 
In the last few years, there has been a high growth in the installation of optical fiber cables 
all over Europe, providing a large transmission capacity. This will lead to a great 
improvement of services offered to users as this capacity will allow networks to carry 
multimedia applications. 
The RACE Programme (Research and Technology Development in Advanced 
Communications in Europe) has been developing the technology that would made this 
possible. Before this technology is made available for deployment, it is required to test if 
the applications and equipment from different sources (Network operators, vendors, and 
users) interwork. 
The European Parliament took in 1992 the initiative to stimulate this demonstration. The 
European Commission launched a call for proposal that resulted in four trans-European 
projects offering broadband services, including multimedia and multi-party cooperative 
working. 
The initiative helped develop a telecommunications service infrastructure and form a basis 
for the promotion and the expansion of broadband communications: operators, users and 
manufacturers have used the broadband platforms for real life testing, and the initiative has 
implemented on a trial basis a wide array of broadband applications. For example, the 
projects offered the first trans-European ATM based services with a relevant impact on the 
development of the future European Information Infrastructure.

THE FIBER INTERCONNECTION INITIATIVE 
• Demonstrate 
* Provide 
• Address a pilot action to show the potential for effective 
broadband communications based on optical Fiber 
a «olid foundation of European collaborative 
research experience 
the issues of interoperability and interworldng of 
networks j 
* Capture the attention øf major sector actors 1 
In a specific action, the European Parliament took the initiative to stimulate the 
demonstration of optical fiber-based communications for illustrating the interworldng 
between centres of excellence. This action was to be seen in the context of preparing for 
the Trans-European Broadband Networks. 
The scope of the action was to financially participate in interconnection costs among IBC 
Islands and High Performance Computer Centers to advance the capability of interworldng 
of these sites and to contribute to common functional specification for trans-European 
network operation following international standards. 
The Commission prepared and launched a call for proposal for interested parties willing to 
participate12. Participation was open to any center of excellence in high performance 
computing or communications. Contracts were awarded, for a period up to 12 months, on 
the basis of competitive bidding of consortia of at least two centers, independent of each 
other and established in different Member States, wishing to demonstrate interworking via 
optical fibre networks. The financial support provided by the Union was applied only to 
part of operational costs of interworking incurred within the Member States, i.e. 
communications charges and specialized equipment within the provisions of the budget 
available (4 MEcus) to this action.

within the Member Slates and through the framework of Community Programmes. 
Testbeds for Integrated Broadband Communications (IBC) and High Performance 
Computing (HPC) will benefit from interworking on a Community level. "Broadband 
Islands" have emerged in all European countries, stimulated either by national initiatives, or 
through the RACE Programme. RACE has created an extended European platform for 
cooperation towards IBC and has significantly contributed to the development of advanced 
telecommunications equipment, services, and applications, such as ATM systems, 
transmission systems, etc. Practically all islands are the results of joint efforts of 
researchers, industry and public network operators. 
This action has improved the conditions for testing and analyzing the impact of the new 
services, applications or end-systems in the networks, and has contributed to the 
development of fibre connectivity and produced an organizational structure to promote and 
expand the use of broadband communications. 
THE CONTEXT 
The projects were operating during the year 1993. By focusing on interconnecting 
Broadband Islands during this relatively short time period, the projects built extensively on 
already existing achievements stemming from other programmes or initiatives. In 
particular, one must mention: 
• Broadband Islands, such as RIA and RECIBA, developed by the Network Operators 
in part with the help of some RACE projects. 
• Broadband applications, such as ESPRIT Project P2091-VIMP. 
• Experimental Pilot Projects, such as RACE Project R2078-TIM and DELTA Project 
D2016-EAST. 
• Existing networks, such a MAN in Dublin and the STAR3 network in Belfast 
• Existing products and prototypes, such as ATM cross-connects and Routers. 
Due to their high involvement in addressing interconnection issues, the projects participated 
heavily in the RACE concertation process where projects contribute by exchanging 
technical information on the issues they are facing and the means they use to overcome 
them. They exchanged valuable information within the RACE Project Line 8, Test 
Infrastructure and Interworking. Through this concertation process, they also provided 
inputs to some RACE Common Functional Specifications. 
The Commission Services monitored the projects' progress through Monthly Management 
Reports and ad-hoc contacts as needed. At the end of their work projects were evaluated 
by independent Auditors. Auditors noted in their report that results were viewed as an 
"interesting and significant demonstration, especially in view of the limited budget and 
limited time span under which that had to be managed " 
KEY RESULTS 
Achievements 
The Initiative helped develop a telecommunications service infrastructure and form a basis 
for the promotion and the expansion of broadband communications: operators, users and 
3 Special Telecommunication Action for Regional Development: the objective of me STAR programme was to improve 
the télécommunication infrastructure capable of hosting advanced telecommunication services. 
\3> 
manufacturers have used the broadband platforms for real life testing, and the initiative has 
implemented on a trial basis a wide array of applications. These are: 
• Video conferencing. 
• Audio-video mail facility. 
• Electronic white board. 
• Shared data processing performed by High Performance Computing systems. 
• Remote provision of super computing facilities. 
• Vision based on line inspection of manufactured parts. 
• Cooperative working. 
• Robotics applications. 
• Demonstration and transfer of technology. 
• Multimedia desktop conferencing. 
• Distance learning by sharing classes in remote locations. 
Who Benefited? 
Users have had the opportunity to experiment various networking arrangements leading to 
a greater network efficiency. A key element of the Initiative was the large number of 
applications from various organizations. Users have had an early opportunity to understand 
the benefits they will draw from IBC applications, thus creating a future demand pull for 
IBC. 
Public Network Operators have drawn lessons on the usage of the new infrastructure. 
The traffic patterns have been analyzed and studied to understand the behavior of 
broadband traffic. Improvements, enhancements, adaptations and administrations of a 
broadband trans-European service are results of the Initiative. 
Manufacturers of cross-connects, routers and other terminal equipment have been able to 
test their equipment in real life usage conditions. In addition, they have collaborated with 
operators to define the quality of service parameters relevant to broadband facilities. 
What Did We Learn? 
The experience gained in distributed applications over high bandwidth links can be used by 
the Public Network Operators, for example to define invoicing rules for ATM services. 
Thus, feedback to the public network operators is of value for their future developments. 
Impact on the European market is however only indirect, through integration of the 
experience gained by the Public Network Operators in their own developments. The 
projects output, if correctly exploited by the public network operators, can thus strongly 
contribute to European cohesion and competitiveness. 
Also, the experience gained through interworking with the concerned Operators for solving 
user specified applications can strengthen their cooperation with respect to similar end-user 
defined applications. Since most projects included public network operators as participants, 
their experience was readily applicable. However as pointed out by a project, one of the 
major difficulties appeared to be the linkage between the PNOs, and the user specific 
requirements. This was particularly true with respect to services and tarification. Technical 
problems, as experienced within the project, were fortunately marginal.

12001-Isabel 
Isabel has interconnected two existing IBC islands, RIA in Aveiro (Portugal) and RECIBA 
in Madrid (Spain) in two successive steps. 
• The first step made available two 2 Mbit/s links from the beginning of the project. 
• The second step consisted in the introduction of ATM in the two islands, 
transporting the ATM cells through a plesiochronous link working at 34 Mbit/s. 
12QQ2 - Tiwnet 
Tironet has implemented a broadband service connection between a Metropolitan Area 
Network in Dublin and an SDH network in Northern Ireland, based on the existing optical 
infrastructure, with enhancements to existing nodes to ensure a minimum throughput of 4 
Mbit/s. British Telecom Northern Ireland owns the optical link to the South and was 
responsible for the transnational link. The link had a minimum capacity of 4 Mbit/s with a 
further increase to 34 Mbit/s. 
12003-Betel 
Betel has established a 34 Mbit/s cross-connect platform over trans-European borders. This 
platform has interconnected FDDI LANs in Geneva, Lyon and Sophia-Antipolis. A 
Connectionless Broadband Data Service was provided and each end terminal connected to 
BETEL using a E.164 addressing scheme. 
12004 'HPC'Vision 
HPC-Vision has set-up a 34 Mbit/s link over trans-European borders using existing 
facilities between Strasbourg and Karlsruhe. The project has used the connection to join 
existing systems installed in both locations.

The Isabel project has interconnected two IBC islands, RECIBA from Telefonica in Madrid 
(Spain), and RIA from Telecom Portugal in Aveiro (Portugal) using ATM over PDH at 34 
Mbit/s. 
As a main objective, the project has verified the interworking between two different ATM 
technologies. The RIA island is equipped with an Alcatel cross-connect, while the 
RECIBA island is equipped with a cross-connect developed by Telefonica. From the 
terminals, access was done through an Ethernet LAN and a router. 
Two bearer services were supported on top of ATM: LAN interconnection and circuit 
emulation at 2 Mbit/s. Isabel mixes different technologies, N-ISDN and ATM over PDH 
transport networks. The two Broadband Islands are interconnected by optical fiber. They 
are directly managed by the R&D Centers of Telecom Portugal and Telefonica, thus 
ensuring a smooth interconnection. 
The Isabel network, first phase, has been used during the BRAIN Summer school in July 
1993, while the second phase, operational since December 1993, will be used for the 1994 
edition of this Summer school. This infrastructure supports two major types of broadband 
applications: Cooperative working and distance learning

Te rast of Europa 
ToiMtofEurop« TIRONET's principal objective was to put 
in place a network facility open for a 
growing body of users and applications. To 
achieve this general growth and expansion, 
TIRONET has established an ongoing 
conference of users and PNOs, the 
Advanced Telecommunications Users 
Conference (ATUC). The ATUC has 
mapped out a strategy for the development 
of both the infrastructure and the value 
added services and applications using that 
infrastructure. 
The project has demonstrated the first 
transborder connection between Belfast and 
Dublin. On this network, Tironet has 
performed the following experiments: 
• Two services: 
• One Service

Provision of shared full text and multimedia electronic 
documents (journals, etc.) by three university libraries involved 
in the consortium, with the possibility of extending this to other 
universities in the British Isles and the European mainland. 
Application of desktop conferencing technology to the 
cooperative development of multimedia materials. 
The Tourism Information and Marketing (TIM) project in 
RACE involves the tourist board from both the Republic of 
Ireland and Northern Ireland, and the availability of this 
broadband connection will provide an excellent opportunity for 
a TIM trial between these two organisations. 
The Educational Access and Support Tools (EAST) project in 
DELTA is developing a set of tools for accessing, interrogating 
and managing multimedia databases of educational material. 
Two of the universities in TIRONET are involved in this project 
and will use the network connection for testing and evaluating 
the use of shared educational resources.

The Betel project has demonstrated multimedia applications with high data rate 
transmission over optical fiber links. The optical platform was between Geneva (CH), 
Lausanne (CH), Sophia Antipolis (F) and Lyon (F). 
The project was based on a trans-European broadband cross-connect infrastructure, using 
asynchronous techniques with a connection oriented facility. This connection has been the 
first international network using ATM technology. The BETEL project experimented 
broadband techniques, providing a significant advance for understanding the broadband 
issues. 
The project has used existing products. It has build a 34 Mbit/s cross-connect trans-
European platform with the following main objectives: 
• to test a cross-connect platform for trans-border links, 
* to support suitable multimedia applications, such as Tele-teaching or Physics 
Analysis Workstation, 
• to give a broadband access to high computing resources, and 
* to test asynchronous transfer techniques.

The project has interconnected two vision systems based on parallel systems (e.g. 
specialized processors and transputer networks), thus extending the availability of 
distributed vision systems. The data transfer was done through a trans-national optical 
network with a rate high enough to be compatible with real time applications. Also, 
friendly man-machine interfaces hid the network characteristics of the system allowing 
users to use the system as a whole. This approach opens the doors for new applications 
through cooperation of two geographically distributed systems, and intensifies the common 
research activities of the partners. 
The distributed system was also open to industries of the partners' regions, in the 
framework of a border crossing demonstration and transfer of technology for the industrial 
application of computer vision. The existence of a public optical link between the project 
partners and the commitment of the regional telecommunication agencies of the partners' 
countries to provide the required transfer rate of 34 Mbit/s has greatly facilitated the 
extension of the existing distributed systems using local networks (e.g. FDDI) to a larger 
public networked system. 
The existing applications used and adapted were the following: 
• Set-up of a distributed high computing power parallel structure based on transputers 
for computer vision applications. 
• Vision-based on-line inspection of manufactured parts. 
• Robotics applications. 
• Set-up of a geographically distributed demonstration and transfer of technology 
center for vision applications.
