First CEENET Workshop on Network Technology, Warsaw, September, 25th 1995

The First CEENet Workshop on Network Technology was held from September 15 until September 25, 1995, in Warsaw, Poland. It took place in the newly erected building of the Polish-Japanese High School of Computing Techniques which provided excellent facilities and suitable infrastructure. At the opening ceremony, short speeches were given by the Vice-rector of the Polish-Japanese School Dr. Andrzej Jankowski, Professor Tomasz Hofmokl the Chairman of the CEENet, Dr. Jacek Gajewski in the name of the Organizing Committee and Professor Oliver B. Popov for the Programme Committee and the lecturers.

The realization of the Workshop was made possible by the generous donations of the Soros Foundation, NATO and the State Committee for Scientific Research of Poland. Moreover, the contributions of SUN, CISCO, Siemens, Rockwell Communications Systems and the major Polish vendors such as Optimus, Inwar, Scientific, ANDRA, Bardex, ATM, the project “Internet for Schools”, and NASK were essential in establishing and operating the computing and communication environment. The Polish Academic and Research Network (NASK) took care of the external connectivity and supplied additional routing devices. Most of the hardware and the software was setup by the lecturers, the Polish-Japanese School staff, the students that work in the High-school project, and NASK.

The Programme of the Workshop

 The Workshop had two different tracks, namely National Network Management and Computational and Communication Infrastructure. Some of the lectures were presented on joint sessions for both tracks which was very well received by the attendees (these included the key note introductory and overview session, the VSAT Technology, the OSPF by CISCO, and certain aspects of network security). The total number of lecturers was fifteen, from ten different countries (Bulgaria, Czech Republic, Estonia,Poland, Austria, Macedonia, France, Romania, Slovenia, and USA).

 In September of 1994, the CEENet MC authorised Oliver B. Popov to work on the scientific program of the workshop. On the CEENet GA meeting in October of 1994 that took place in Budapest, the Programme of the Workshop was presented and approved. Moreover, a Programme Committee was elected with a specific task to work on the initial propoasal and the selection of the prospective candidates for lecturers. The Program was subsequently slightly revised at the CEENet GA meeting in March of 1995 at Bled, Slovenia. Some of the lectures such as Lars Poulsen, August Jauk, Jan Haering, Anne Villems, and Krzystof Silicki made valuable comments about the programme and significantly improved its content and overall relevance. Regrattably, there were some last minute cancelations by certain lecturers, which put additional strain on the workshop leadership. Fortunately, these diffculties were vercome via the extreme team-spirit of all the lectures teaching at the Workshop. The presence at the Inet ’95 Workshop, the opportunity to work with George Sadowsky and his team, as well as to have almost daily meetings with the prospective CEENet W/shop lecturers proved to be crucial to the success of the workshop. The final programme, which was carried out at the Workshop, is the following one (T1, T2 mean Track #1 and Track #2 respectively):

On Friday, September 22, 1995 the team of lectures was joined by an expert from CISCO-France , Mr. Roland Acra, the Director of the Consultants Team who spoke about the variety of routing policies and algortihms. His talk, which lasted almost three hours, was very well received and induced great interest among the attendees.

 There were 7 1/2 working days in total. Two excursions have been organized: a sight seeing (on Thursday, September 21st)and the visit to the Military School for Telecommunication (on Sunday, September 24th). The workshop ended with a Gala dinner, where awards, certificates and impressions from the preliminary analysis of the evaluation forms have been presented..

The Participants (Students, Lecturers and VIPs)

There were eighty attendees (students) at the Workshop from twenty four countries. These included the members of the CEENet as well as other ones that aspire to become members of the organizations in the near future. Since some of the countries in the CEENet community have highly developed network structure and organization they waved their right to send students either completely or partially (Austria, Hungary, Poland and Czech Republic).

Aftermath the Workshop

It has been agreed that after the Workshop, a mailing list should be established as forum for all the attendees of the Workshop. Also, due to additional support by Soros Foundation, the materials presented at the Workshop will be put on the WWW server of the CEENet organization. Moreover, the team of lecturers soon starts to work on the proceedings of the workshop that should be published in a form of book along with a short dictionary of networking(according to the survey it is going to be eagerly waited by the


The Workshop has been both a learning experience and organizational challenge for all of us. Most of the lecturers came early and setup the laboratories from scratch, working long hours into the night. The organizers, from boarding facilities, to the transportation, lecture halls and laboratories did their best to make it work. With one or two exceptions, the materials for the lectures were given concurrently with the lectures.

Clearly, the kind of effort the Workshop is, it proved to be a mosaic of commitments, devotion, enthusiasm and involvement.

The goals of the Workshop were to promote the benefits of the contemporary network technology, to introduce the Internet paradigm in Central and Eastern European countries and to identify common problems in building national academic infrastructure. The comments of the attendees during and after the Workshop prove that these goals have been satisfied

to a respectable degree by the largest project undertaken by the CEENet so far. A standard and a reference have been established to be maintained and improved in the future for which there is a consensus on at least one point: there must be next workshop.
