Report on the Fifth CEENet Workshop in Network Technology Budapest, August 17-25, 1999 Site, partcipants and sponsors ============================== After three years, and the workshops in Zagreb and Bratislava, the CEENet has organized its annual Network Technology Workshop again in Budapest, at the CEU Conference Center. This was consistent with the new concept introduced by the workshop organizers and approved by the CEENet GA and MC, namely to promote the CEU CC as a permanent site for CEENet educational activities. The decision was based on the excellent networking facilities already present, the satisfactory level of accommodation, and the favorable geographical position of Budapest with respect to many CEE countries, which makes the cost and the length of travel acceptable for many of the participants. The Fifth CEENet Workshop on Network Technology took place in Budapest, Hungary, from August 17 to August 25, 1999. The opening of the Workshop was on Tuesday, August 17, at the Central European University Conference Center, with the presence of officials from OSI, CEU, Hungarnet, CEENet, the Organizing and Programming Committees, the CEENet team of lecturers, and the attendees. A short welcome speeches were given by the Chairman of CEENet Dr. Jan Gruntorad, by Professor Layos Balint in the name of Hungarnet, Dr. Gabor Farcas from the CEU, Mr. Jurgens Hess from OSI, D-r Jacek Gajewski as the Chair of the Organizing Committee and Professor Dr. Oliver B. Popov for the Programme Committee and the Lecturer's team. In addition, the selection of the lectures from the Bratislava Workshop in a form of book under the title "The Fourth CEENet Workshop on Network Technology: Open Networks - Close World" was promoted and distributed among the sponsors, the media and the attendees. After the ceremony, there was a small cocktail, and meeting with the attendees where they were introduced to the instructional facilities, the lab and equipment usage policy. The workshop (preceeded by the OSI summit) was attended by 105 students from following 25 countries: Albania, Armenia, Azerbaijan, Belarus, Bosnia & Hercegovina, Bulgaria, Croatia, Czech Republic, Estonia, Georgia, Hungary, Kosovo Region, Kyrgyzstan, Lithuania, Latvia, Macedonia, Moldova, Mongolia, Poland, Romania, Russia, Slovakia, Slovenia, Ukraine, USA, Uzbekistan. They were teached by a team of 25 lecturers and instructors from following 13 countries: Canada, Croatia, Estonia, Finland, Germany, Macedonia, Nederland, Poland, Romania, Slovenia, Sweden, Switzerland and USA. The realization of the Workshop was made possible by the generous donation by the Open Society Institute (Soros Foundation). Moreover, the in-kind contributions of CISCO, SUN, Crawford Communications, 3Com, New Deal, O'Reilly and Associates, MatavCom and the NetSat (with a total value of circa $37000), as well as Hungarian Soros Foundation and CEU were essential in establishing the right learning environment. The Programme of the Workshop ============================= The Scientific Programme of the Fifth Workshop was presented at the CEENet GA meeting in Warsaw at the end of May, 1999. The new format of the previous workshop in Bratislava, namely to have three tracks, a technical one, the services and third on distance learning was maintained. The latter was preceeded by a distance learning pre-course, which was essential in choosing right level of students with satisfactory command of English. The lectures started on Wednesday morning, August 18, and ended a week later, on Wednesday noon, August 25.

The Workshop had again two strings of value added events. The Sponsor's Spotlight were given by Craword Communications, New Deal, 3Com, Matav Com and NetSat Express. The "Evening Lectures" covered the following topics: Mathematical Modeling in Life Sciences, The Global Distributed Intelligence, The Power of Electronic Publishing vs. the Dominace of the Traditional Publishing Houses and Monopolies, DVB Technology, and SPAM. During the closing session, the awards were presented to the best participants in each track. O'Reilly and Associates, for the second year in a row, donated books for about 35 000 USD, that were distributed to all of the participants. Few days before the workshop started, there was the traditional summit of all of the OSI Automation and Internet co-ordinators from the CEE and FSU countries. We were also delighted to have for a few days Mr. Jonathan Peizer, Chief Information Technology Officer of the Soros Foundation. This rare opportunity was used to have a fruitful discussion with Mr. Peizer and Mr. Hess about the future of the workshops and the Internet technology based education. The whole event ended with the Gala dinner, at a Pusta site about 25 km from Budapest, and with a nice programme of Hungarian National folk dances and songs and horse riding and training.
