SOBRE A 
Demonstração do Interfuncionamento Via Redes Ópticas 
Síntese dos Resultados 

Demonstração do Interfuncionamento Via Redes Ópticas 
Síntese dos Resultados 
O Parlamento Europeu tomou em 1992 a iniciativa de incentivar a demonstração de 
comunicações ópticas na Comunidade, apoiando experiências de interconexão de 
tecnologias de banda larga, como as "Ilhas de Banda Larga" e os Centros de Cálculo de 
Elevado Desempenho em diferentes Estados-membros. Esta iniciativa foi baseada no 
trabalho de I&D já realizado no âmbito do Terceiro Programa Quadro de Investigação e 
Desenvolvimento Tecnológico Comunitário (1990-1994). 
Esta iniciativa abriu o caminho às Redes Transeuropeias de Comunicações Integradas em 
Banda Larga (RT-IBC), complementando trabalhos significativos já realizados nos 
Estados-membros, graças ao quadro dos programas de IDT da União. 
As Ilhas de Banda Larga surgiram em todos os países europeus - incentivadas por 
iniciativas nacionais ou através do programa RACE1 - e criaram uma extensa plataforma 
europeia de cooperação com vista às EBC. Contribuíram significativamente para o 
desenvolvimento de equipamentos, serviços e aplicações de telecomunicações avançadas, 
como sistemas de comutação e transmissão de alta velocidade. A maioria das Ilhas de 
Banda Larga são o resultado de esforços conjuntos de investigadores, indústria e 
operadores de rede. 
Para materializar este estímulo, a Comissão Europeia lançou um convite a manifestações 
de interesse2 aberto a todos os centros de excelência no domínio da computação ou 
comunicações de elevado desempenho. Este convite deu origem a quatro projectos3 com 
uma duração máxima de 12 meses. Estes projectos proporcionaram serviços em banda 
larga, incluindo multimedia e trabalhos de cooperação entre vários parceiros. O apoio 
financeiro fornecido pela União foi aplicado apenas a parte dos custos operacionais do 
interfuncionamento suportados nos Estados-membros, ou seja, encargos de comunicações 
e equipamentos especializados abrangidos no orçamento disponível (4 MECU) para esta 
acção. 
Os projectos eram os seguintes: 
Isabel para interconexão de Ilhas de Banda Larga entre Espanha e Portugal; 
Tironeí para interconexão de Ilhas de Banda Larga entre a Irlanda do Norte e a República 
da Irlanda; 
Betei para interconexão de instalações na França e na Suíça; 
HPC-Vision para interconexão de instalações em França e na Alemanha. 
Os projectos decorreram durante o ano de 1993. O documento técnico anexo fornece 
pormenores sobre a organização dos projectos. No final dos seus trabalhos, os projectos 
foram avaliados por auditores independentes. Os auditores declararam que os resultados

Decisões E/1848/92, de 30.11.1992 e E/2106/92 de 22.12.1992 da Comissão. 
correspondiam a uma demonstração interessante e significativa, especialmente tendo em 
vista o orçamento e a duração limitados que condicionaram a sua gestão. 
Dado incidirem essencialmente em questões de interconexão, os projectos coordenaram 
os seus esforços com projectos RACE e trocaram informações técnicas sobre os 
problemas que enfrentavam e os meios utilizados para os resolver. Os projectos deram 
ainda contributos para algumas especificações funcionais comuns do RACE. Incidindo na 
interconexão de Ilhas de Banda Larga durante um período relativamente curto, os 
projectos apoiaram-se em grande medida em resultados já obtidos noutros programas ou 
iniciativas. Concretamente, há que referir: 
• Ilhas de Banda Larga, como a RIA (Portugal) e a RECIBA (Espanha), 
desenvolvidas pelos operadores de rede em parte com o auxílio de alguns 
projectos RACE; 
• Aplicações de banda larga, como o projecto VIMP do ESPRIT; 
• Projectos-piloto experimentais, como o projecto TIM do RACE e o 
projecto EAST do DELTA; 
• Redes existentes, como a rede metropolitana em Dublin e a rede STAR4 
em Belfast; 
• Produtos e protótipos existentes, como os comutadores de alta velocidade 
(ATM e orientadores de rotas). 
Esta iniciativa contribuiu para desenvolver uma infra-estrutura de serviços de 
telecomunicações e formar uma base para a promoção e expansão das comunicações em 
banda larga: operadores, utilizadores e fabricantes utilizaram as plataformas de banda 
larga para ensaios reais. Por exemplo, os projectos proporcionaram os primeiros serviços 
ATM transnacionais com impacto significativo no desenvolvimento da futura 
infra-estrutura europeia da informação. 
Os projectos implementaram experimentalmente uma vasta gama de aplicações de banda 
larga existentes ou adaptadas. Estas aplicações de banda larga poderão formar, num 
futuro próximo, a base para a oferta aos utilizadores finais de comunicações em banda 
larga. As referidas aplicações são: 
Videoconferência 
Correio Audio-vídeo 
Quadro negro electrónico 
Tratamento partilhado de dados por sistemas de computação de elevado 
desempenho 
Oferta à distância de meios de supercomputação 
Inspecção em linha baseada na visão de componentes fabricados 
Trabalho em cooperação 
Aplicações robóticas 
Conferência multimedia no escritório 
Ensino à distância através da partilha das aulas em locais distantes. 
Acção especial no domínio das telecomunicações para o desenvolvimento regional: o objectivo do programa STAR 
melhorar a infra-estrutura de telecomunicações, de modo a poderem ser oferecidos serviços avançados de telecomunicações. 
Como resultado da iniciativa, os utilizadores da banda larga tiveram a oportunidade de 
experimentar um grande número de aplicações de banda larga de diversas organizações, 
beneficiando de uma primeira oportunidade para compreender os benefícios que podem 
colher das aplicações IBC, criando assim uma potencial procura das IBC. 
A experiência adquirida pelos operadores de redes públicas (ORP) através do 
interfuncionamento na preparação de aplicações especificadas pelos utilizadores reforçou 
o seu conhecimento sobre as oportunidades oferecidas pelas aplicações de banda larga. Os 
operadores ficaram também a conhecer melhor questões técnicas ligadas às aplicações 
distribuídas de banda larga em ligações de grande largura de banda, para, por exemplo, 
definir regras de facturação aplicáveis aos serviços ATM. Enquanto as reacções dos 
utilizadores se revestiram de interesse imediato para os planos futuros dos ORP, o 
impacto no mercado europeu foi indirecto, através da integração da experiência adquirida 
pelos ORP nas suas próprias actividades. Os resultados dos projectos, caso sejam 
correctamente explorados, poderão contribuir fortemente para a coesão e competitividade 
da Europa. 
Os fabricantes de correctores, orientadores de rotas e outros equipamentos terminais 
puderam ensaiar os seus equipamentos em condições reais de utilização. Além disso, 
colaboraram com os operadores na definição dos parâmetros de qualidade do serviço 
aplicáveis à banda larga. 
Com base nestas realizações, a maioria dos projectos decidiu prosseguir o seu 
empreendimento oferecendo a sua infra-estrutura a projectos de investigação no quadro 
do RACE e da iniciativa Redes Transeuropeias - Comunicações Integradas em banda 
larga (RT-E3C). Deste modo, oferecem a oportunidade de utilizar a competência 
adquirida nas experiências de comunicações em banda larga na Europa. Além disso, 
oferecem uma plataforma para experiências reais que são essenciais para compreender as 
questões ligadas à implantação de aplicações de banda larga. Estão ainda a estudar a 
possibilidade de participar na grande tarefa de interconexão dos computadores centrais 
nacionais (Hosts) do ACTS5. 
Programa especifico de investigação e desenvolvimento tecnológico no domínio das tecnologias e serviços de comunicações

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 a pilot action to show the potential lor effective 
broadband communications bated on optical Fiber 
* Provide a «olid foundation of European solutoorative 
research experience 
* Address the issues of interoperability and interworking of 
networks 
•Capture the attention of major «ctor acton 
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 ihc framework of Community Programmes. 
Testbeds for Integrated Broadband Communications (IBC) and High Performance 
Computing (HPC) will benefit from interworking on a Community level. "Broadband 
Islands4' 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 Tricicommunication 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. 
12Q02 • 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. 
12004 -HPC-Yuion 
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 Telefónica. 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 met of Europe 
To roet of Europe 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 facihty 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 umversities 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 BEIEL 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 parmers. 
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.
