om 
demonstration av samverkan genom optiska nätverk 
Resultatsammanställning 

Demonstration av samverkan genom optiska nätverk 
Resultatsammanställning 
Europaparlamentet tog 1992 initiativet att stimulera demonstration av optisk 
kommunikation inom gemenskapen genom att hjälpa till med hopkopplingsförsök med 
bredbandsteknik, som "bredbandsöar" och avancerade datacentrer (High Performance 
Computer Centres) i olika medlemsstater. Detta initiativ var baserat paa Forsknings- och 
Utvecklingsarbeta, som er blevet utfoert i det tredie europaeiska forskningsramprogram 
Third Framework Programme of Community Research and Technology Development 
(1990-1994)'. 
Detta intitativ har banat väg för transeuropeiska nät och integrerad 
bredbandskommunikation genom att komplettera det redan betydande arbete som gjorts 
inom medlemsstaterna och genom unionens RDT-programs ramverk. 
Bredbandsöar har uppstått i alla europeiska länder - antingen genom nationella inititativ 
eller genom RACE'-programmet - och har skapat en utvidgad europeisk plattform för 
samarbete med sikte på IBC. De bidrog avsevärt till utvecklingen av avancerad 
telekommunikationsutrustning, tjänster och applikationsprogram, såsom system för 
höghastighetskoppling och överföring. De flesta bredbandsöar är resultat av forskares, 
industrins och nätverksoperatörers gemensamma ansträngningar. 
För att åstadkomma denna stimulering har Europeiska kommissionen efterlyst2 
intresseanmälningar från alla centrer för experter inom avancerad (high performance) 
databehandling eller kommunikation. Detta resulterade i fyra projekt3 under en tid av upp 
till 12 månader. Dessa projekt erbjöd bredbandstjänster, inklusive multimedia- och 
multipartskooperativ. Det ekonomiska stödet från unionen gällde bara en del av 
driftskostnaderna för samverkan inom medlemstaterna, dvs. avgifter för kommunikation 
och specialutrustning inom befintliga budgetanslag (4 milj. ecu) för denna åtgärd. 
Dessa projekt var 
Isabel som kopplade ihop bredbandsöar mellan Spanien och Portugal, 
Tironet som kopplade ihop bredbandsöar mellan Nordirland och Irland, 
Betel vars mål var att koppla ihop platser i Frankrike och Schweiz och 
H PC-Vi si on som kopplade ihop platser mellan Frankrike och Tyskland. 
Projekten drevs under 1993. Bifogade tekniska dokumentation ger närmare upplysningar 
om projektens organisation. Efter avslutat arbete utvärderades projekten av oberoende 
revisorer. Revisorerna uppgav att resultaten var en "intressant och betydande 
demonstration, särskilt med tanke på den begränsade budget och tidsrymd under vilket 
detta skulle klaras. "

På grund av att de var så involverade i hopkopplingsfrågor, samordnades projekten med 
RACE-projekt och man utbytte teknisk information om de frågor man ställdes inför och 
de medel man använde för att lösa dem. Projekten stod även för tillförsel av en del av 
RACE'S gemensamma funktionsspecifikationer. Genom att fokusera på hopkoppling av 
bredbandsöar under denna relativt korta tidsperiod, byggde projekten i stor utsträckning 
på redan uppnådda landvinningar från andra program eller initiativ. Särskilt bör här 
nämnas 
- Bredbandsöar, såsom RIA (Portugal) och RECIBA (Spanien) som utvecklats av 
nätoperatörer delvis med hjälp av en del RACE-projekt. 
- Bredbandsapplikationer, såsom ESPRIT-projektet VIMP. 
- Experimentella pilotprojekt, såsom RACE-projektet TIM och DELTA-projektet EAST. 
- Befintliga nätverk, såsom Metropolitan Area Network i Dublin och STAR4-nätverket i 
Belfast. 
- Befintliga produkter och prototyper, såsom höghastighetsväxlar (ATM och router). 
Initiativet hjälpte till att utveckla en infrastruktur för telekommunikation och bilda en 
grund för främjande och utvidgning av bredbandskommunikationer: operatörer, användare 
och tillverkare har använt bredbandsplattformarna för verkliga försök. Till exempel erbjöd 
projekten de första transnationella ATM-baserade tjänsterna med en effekt som hade 
betydelse för utvecklingen av den framtida europeiska infrastrukturen för information. 
Projekt har på försök genomfört en lång rad av redan befintliga eller anpassade 
bredbandsapplikationer. Dessa applikationer skulle inom en nära framtid kunna utgöra en 
grund för att tillhandahålla bredbandskommunikationer till slutanvändare. Dessa är 
följande: 
- Videokonferens. 
- Elektronisk ljud- och bildöverföring. 
- Elektronisk anslagstavla. 
- Delad databehandling som utförs av avancerade (high performance) datorsystem. 
- Fjärrleverans av avancerade datafunktioner. 
- Inspektion av tillverkade delar via datorskärm. 
- Kooperativt arbete. 
- Applikationer för robotteknik. 
- Multimedia desktop-konferenser. 
- Distansutbildning genom delade klasser på avlägsna platser. 
Som ett resultat av detta initiativ har bredbandsanvändare haft tillfälle att experimentera 
med ett stort antal bredbandsapplikationer från olika organisationer, vilket tidigt givit dem 
tillfälle att förstå vilka fördelar de kommer att få av EBC-applikationer, och sålunda skapa 
en framtida efterfrågan på IBC. 
Den erfarenhet som vunnits av operatörer på allmänna nätverk genom samverkan för att 
lösa de särskilda användarapplikationerna har befäst deras kunskaper om de möjligheter 
som bjuds genom liknande bredbandsapplikationer. De fick också en bättre förståelse för 
tekniska frågor i distribuerade bredbandsapplikationer via nät för höga bandbredder, till 
4 Special Telecommunication Action for Regional Development. Målet för STAR-programmet var att förbättra inrrastruktruen för 
telekommunikation med avancerade telekommunikationstjänster. 
exempel att fastställa annonseringsregler för ATM-tjänster. Medan gensvaret från 
användarna var av direkt värde för operatörernas framtida utveckling, var effekten på 
europamarknaden indirekt, genom införlivande av den erfarenhet som vunnits av 
operatörerna i deras egen utveckling. Utbytet av projekten kan sålunda, om det används 
rätt, starkt bidra till europeiskt sammanhang och europeisk konkurrenskraft. 
Tillverkare av korskopplingar, routers och annan terminalutrustning har kunnat testa sin 
utrustning under verkliga förhållanden. Dessutom har de samarbetat med operatörer för 
att fastställa kvaliteten på parametrar för bredbandsfunktioner. 
De flesta projekten har beslutat att genom att bygga på dessa landvinningar fortsätta sin 
verksamhet genom att erbjuda sin infrastruktur till forskningsprojekt inom RACE och 
transeuropeiska nät och integrerad bredbandskommunikation. Därmed erbjuder de 
möjligheten att bygga på den expertis som utvecklats i experimenterandet med 
bredbandskommunikation över Europa. Dessutom erbjuder de en plattform för reella 
experiment, som är nyckeln till förståelse av frågorna i samband med användning av 
bredbandsapplikationer. De undersöker vidare möjligheten att delta i den stora uppgiften 
att sammanlänka ACTS5 nationella värdar. 
Särskilt program för forskning och teknisk utveckling inom området för avancerade kommunikationstekniker och tjänster.

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 bated on optical Fiber 
a soiki foundation of European collaoomtive 
research experience 
the issues of interoperability and interworking of 
networks 
Capture the attention of ma)or sector actors 
In a specific action, the European Parliament took the initiative to stimulate the 
demonstration of optical fiber-based communications for illustrating the interworking 
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 interworking 
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 Télécommunication Action for Regional Development: the objective of the STAR programme was to improve 
the telecommunication infrastructure capable of hosting advanced telecommunication services. 
_ 
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 
defmed 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. 
12002 - Tironet 
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. 
17004 -HPC-Visian 
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

12002 - Tironet 
To raat of Europe 
To root of Europ* 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 
Development 
•Two 
Experimental 
Pilots Provision of a super computing facility by a university in Belfast 
to application users in Dublin. 
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.

Partial Vision System and Control (Strasbourg) 
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.
