Background
 Call
for Proposals issued by European
Parliament (1992):

Demonstration of Interworking Via Optical
Networks (DIVON).
 Four projects selected:
 I2001 - Isabel (Portugal - Spain)
 I2002 - Tironet (Ireland)
 I2003 - Betel (France - Switzerland)
 I2004 - HPC-Vision (France - Germany)

Key aspects
 Very
unique collaboration between
Telecom Operators, Information
Technology suppliers and advanced user
communities (High Energy Physics & High
Education Institutes).
 Small,
well focused, project with few
partners.
 Short

Applications
 High

speed distributed computing:
allow transparent (i.e. location independent)
access to shared resources):
» CPU, disk and tape servers.
 High
quality Tele-Teaching:

conventional (Tele-Amphi).

remote teacher supervising students
(application sharing).

Results

First Trans-European ATM 34 Mb/s links in
operation from 9/93 through 12/93.

Seamless access to tape and disk servers
located at CERN from IN2P3 (Lyon) achieved on a
near-production basis.

Advanced Tele-teaching scenarios demonstrated
between EPFL (Lausanne) and Eurecom Institute
(Sophia Antipolis).

Benefits
 Telecom


Operators:
validation of ATM transport over international optical
fiber circuits.
better understanding of advanced applications
requirements and services necessary to support these.
 Information

Technology Industry:
validation of ATM equipment (cross connect, adapters,
routers) in a realistic production environment.
 Users:
 deployment of existing applications over real Wide Area
ATM network.

Follow-on projects (I)
 European
ATM pilot (1994-1995) and its
EU funded successor JAMES (1996-1997):


Broadcasting of some academic training
seminars from CERN to Finland.
RACE & ACTS summer school 1995, 1996.
 TEN-34


Olivier Martin
(1997-1998):
Pan-European 34 Mb/s backbone
interconnecting National Research Networks.
Two sub-networks, one of which uses ATM in a
very similar way to BETEL.

Follow-on projects (II)
 BETEUS

(1994-1995):
Tele-teaching part of BETEL expanded to more
partners, CERN included, and more
aggressive work plan.
 STEN
(Scientific Trans-European Network)
- (1994):

Olivier Martin
Distributed conferences and Video on Demand
(VoD) services.

Final comments

Back in 1993, Betel was a very advanced
project:
» Europe was lagging behind the USA with 2 Mb/s international
links and little developed national research networks.
» Major progress have been accomplished since then (TEN-34,
JAMES), in terms of general purpose European networking
infrastructure for research.
» It is not unreasonable to think that BETEL contributed to these
very positive developments.

However, technology is moving very fast:
» Today’s requirements are a factor 5-10 higher than in
1993, i.e. 155/622 Mb/s test beds are urgently needed.

Conclusions
 Very
unique collaboration between
Telecom Operators, Information
Technology suppliers and advanced user
communities (High Energy Physics & High
Education Institutes) with active EU
support.
 Strong synergy between the actors above,
may not be as well exploited in Europe as
it is in the USA.
