CEENGINE in the top 10% of the EC projects

CEENGINE – recent flagship project of CEENET has come to an end, after 42 months of operations. The final review of the project took place in Brussels on 5/2/2014, and we are happy to announce, that independent reviewers ranked this project “EXCELLENT” placing it in the top 10% of all EC-funded projects, right next to leading projects like GEANT.

The project, executed solely by CEENET as its only contractor, focused on contiuous support to Eastern European NREN in strengthening national infrastructure and the integration with GEANT.

The highlights of the project, executed between 2010-2014 include

  • NRENs Policy Workshop in Bucharest, Romania, 2011 (Eastern Partnership Event) coorganised with TERENA & GEANT
  • NRENs Users Workshop in Kiev, Ukraine, 2013, coorganised with PICTURE project
  • NREN Technology Workshop in Tbilisi policy, users and technologies)

CEENET also executed an intensive lobbying campaign resulting in application of new membership scheme in GEANT (and admission of NRENS from Armenia, Azerbaijan, Belarus, Moldova and Ukraine to GEANT).
CEENET itself has also secured a place in GEANT, where – thanks to collaboration with TERENA – we are responsible for activities related to digital inclusion and services dissemination in Eastern Europe. It is extremely important, because thanks to streamlining our activitied with GEANT we can continue to support our NRENS in more effective way.

CEENGINE Network Technology Workshop on security

Our last workshop – CEENGINE NRENs Security Workshop was organized in Tbilisi, from 4th  to 7th of December, 2013. The event co-organized by CEENET/CEENGINE and GEANT provided a number of presentation on security technologies, policies and general matters relevant to NRENs for over 60 participants from Europe. Hosted in excellent venue of Radisson Iveria Blu Tbilisi, within beautiful surroundings of the ancient city, the workshop provided a nice conclusion of the project and marked the start of closer cooperation with GEANT project.

The programme included 2 days of lectures organised by CEENGINE and one day of relevant security topics from GEANT Campus Best Practices activity. For the first time in CEENET events, eduroam was available, thanks to FUNET.

CEENGINE NRENs Users Workshop – 22nd May 2013 in Kiev

CEENGINE NRENs Users Workshop took place on 22nd May 2013 in Kiev, Ukraine.

The event organised by Central and Eastern European Networking Association (CEENET) within its  FP7 CEENGINE project, was hosted by Ukrainian Research and Academic Network  (URAN) in the premises of Kiev Politechnic Institute (KPI).

The funding for the event came from DG-CONNECT and CEENET (who co-fund CEENGINE project) and from Eastern Partnership (EaP) Platform IV/ Multilateral Part of the European Neigborhood Policy Instrument (ENPI) who provided substantial financial support to the project logistics and travel of the participants.

The Workshop was attended by over 70 paticipants from 14 countries, with majority representing EaP stakeholders in R&D – identified as important NRENs users by CEENGINE project. The event also attracted government representatives from Moldova, Ukraine & Belarus. European Union was represented by DG-CONNECT, a number of selected infrastructure projects (GEANT, EGI, DRIHMS, Global Excursion) and organisations from NRENs environment (JANET, TERENA, CEENET).

The objective of the workshop was to involve NRENs users in shaping NRENs future, to turn NRENs users into NRENs supporters, rather than passive consumers of NRENs services.  For this purpose a workshop was organised into 4 sessions,  aiming to discuss the following issues:

  1. „Background preparation” – a session devoted to explaining the case of NRENs and research infrastructures now, in Horizon 2020 and to discuss related collaboration between EaP countires and Europe
  2. „Meet the leaders” – a session demonstrating the most relevant and promising, selected projects supported by European Commission, who may be looking for partners from EaP countries.
  3. „Local dimension” – a set of presentations showing the status and the future plans for e-Infrastructure development in EaP region.  This session included an interesting discussion on development of regional network along the eastern frontiers of GEANT.
  4. „Challenges” – the objective of this part of the event was to discuss the role of key stakeholders in eInfrastructure in its development – including the future ownership, roles and responsibilities, pending issues.

Workshop agenda & presentations:

Session I. Background preparation

The workshop provided good dissemination of eInfrastructures supported by FP7 programme. The participants were very much interested in GEANT services that may be potentially offered to the community within GN3+ (Campus Best Practices, EduRoam, Videoconferencing). Further dissemination of these is required in the region and there is clear demand for future events of this type.

One of important recommendations of the workshop is the need of synchronisation of regional initiatives (especially in the area of the hot topic of building EaP countries backbone spanning NRENs of the region). A success of the event should be also attributed to the co-location of relevant events from different projects (CEENGINE and PICTURE) resulted in increased attendance and impact of each of events. We shall investigate the means to ensure similar coordination in the future.

CEENET Workshop on Network Policy, Kiev, April 2-6 2003

This workshop was aimed to help the Ukrainian scientific community to organize a pan-ukrainian academic computer network. After several years of local rivalries between several, sometimes geographically spread local initiatives, the four organizations (MoE, State Committee for Communication, AoS, Ukrtelecom), with the political support of President Kuchma, decided to create a new academic network organization (called UNREN). UNREN will have a form of an association and will be responsible for maintaining a vital data link to european backbone GEANT, the optimization of links within the country and the cooperation of already existing sub-networks. A group of experts from NATO countries shared their know-how in design and running of the national academic networks, in the inclusion of various user groups and small remote academic centres as well as in possible economic models, possible for UNREN association. UNREN, being at the time of the conference only few weeks .old., could not fully describe its future structure and organization. The participation of the National Telecom in NREN, which is a unique situation in Europe, arousedmany reservations and fears. This reservations were openly expressed and were intensified by the fact that the link to GEANT is nearly idle. On the other hand the fruitful cooperation of UkrTelecom is potentially a great asset for the emerging UNREN.

Eighth CEENet Workshop in Network Technology – Engineering the Virtual Silk Highway, August, 19-29, 2002, Budapest, Hungary

The dynamic and innovative nature of the CEENet Education Programme with respect to the organization and the execution of the workshops in the areas of technology, management and policy was broaden and reinforced again during the “NATO ANW – Eighth CEENet Workshop on Network Technology” held in Budapest from August 19 to August 29, 2002, colored for the first time with hands-on exercises using a real Virtual Silk Highway set-up and an extensive programme on VSAT technology.

Request for the Workshop

The workshop was a response to the request from Central Asian and Caucasus NRENs, which were in urgent need to train their technicians, in view of  the foreseen delivery of the Silk set-ups in the near (2002 and 2003) future. ANW application has been sent before the Jan 15th deadline, and the timely decisions of the NATO Science Committee and Networking Panel, as well as splendid support of the local host (CEU CC) made all preparations very easy. 

Number of Participants
Workshop has been planned for 32 participants: 3 candidates from each of 8 countries, involved in Silk project, have been invited. For the last 8 places candidates from other CEE countries, with clear interest in VSAT technology have been invited. Not all NRENs from Silk countries were able to nominate 3 candidates, also in the very last moment, 2 candidates from Turkmenistan could not leave their country. Thus additional students from countries, which do not need Hungarian visa, have been invited. Altogether, due to a very efficient visa support organized by CEU Conference Centre, 33 students from 18 countries participated in the workshop. For those technicians from Silk countries, whose command of English was not enough to follow the lectures, a translation to Russian language has been provided.It is clear that the combined efforts of the organizers, the lecturers, the sponsors, and more important, the interest and the diligence of the students, produced rather exceptional results and fulfillment of all the objectives set prior to the Workshop.

Set-up of the VSAT Antenna
Prior to the workshop, the NATO Co-director Dr Jacek Gajewski, visited DESY-Hamburg, to take part in the VSAT vendor training and arranging the details of hardware delivery to Budapest and the software installation.
The hardware has been shipped by a truck. Unfortunately the equipment couldn’t be sent to Hungary as an ATA-Carnet demonstration equipment, since it already was on a temporary residence in Germany (bound for
Central Asia/Caucasus). Nevertheless, the custom clearance in Hungary has been done effectively within 4 hours with the help of professional custom agent. In parallel a (successful) application has been issued to obtain
the operation license from Hungarian Radio-Frequency authority. During the next 2 days two antennas have been mechanically set-up, and later within one day the two-way VSAT communication has been established by a team of CEENet lecturers. Valuable comments from this installation process have been distributed and will be used in subsequent installations in Silk countries.

Books Donation for Students
The education environment, due to generous donation of equipment by CISCO, and the previous preparations by the organizers, the staff of CEU CC, and the core lecturers was more then adequate and the operations were most of the time flawless. Due to the another donation provided by O’Reilly and CISCO Press in books, estimated value of about 35 000 USD, all of the participants and their respective organizations and institutions were
presented with much needed literature and software, often rather difficult to obtain in their developing countries.

CEENET (Flying) Workshop on NREN Creation (Prague, Warsaw, Tartu) July 2002

The ‘flying’ workshop took place in July 2002 and was sponsored by OpenSociety Institute.

The NATO Science Program, with which CEENet has a lasting partnership, has developed an Internet infrastructure project, called the Silk initiative, to support Central Asia and the Caucasus. All of the OSI foundations in the region, having in mind that the long range goals of Silk coincide with their goals, participate in this project.
NATO is providing the initial funding, some political support, and a major stimulus to get things started. However, NATO has set 3 criterias before they will implement Silk in any of the countries. The criteria are partly in response to discussions with OSI as to how Silk could promote long term solutions for education/civic connectivity problems in the region.
Before NATO implements Silk in any of the countries:
  1. The country should have a registered national research and education network (NREN)
  2. The NREN needs to get a satellite license
  3. The NREN needs to have a governance structure, cost-sharing plan and long term development strategy.
Of these three, the second is the easiest. The first and third requirements are quite a bit tougher. Academic communities are now working to develop and register NRENs (the NRENs are already registered in Armenia, Georgia, Kazakhstan, Tajikistan and Uzbekistan, and work is underway in Kyrgyzstan and Azerbaijan).
OSI and CEENet are interested in developing a training program for the 8 NRENs. The whole project includes developing an NREN Handbook (this project has just been done by CEENet) and providing training and exposure to working NRENs in Central Europe and the NIS (present workshop). A short trip to the NRENs in Prague (CESNet), Warsaw (NASK), and Tartu (EENet) has given the Central Asian/Caucasus NREN leaders a deep knowledge of the issues they need to be aware of, such as:
  • governance, board structure and development
  • licensing
  • cost-sharing, funding mechanism, accountability and transparency
  • strategic partnerships with ministries of education, major ISPs.
The workshop had the the form of several lectures, followed by in-situ visits and panel discussions in 3 countries, where successful NRENs are operating since several years. These 3 countries have been chosen to give a variety of possible funding models: from half-commercial (NASK) and its less-commercial, sometimes competitor, (POL34) in Poland, via hybrid
commercial-association model of CESNET in Czech Republic to fully government funded EENet in Estonia. The countries were visited in order Czech Republic, Poland and Estonia, mainly due to travel cost effectiveness reasons.
The Seventh CEENet Workshop in Network Technology, August, 20-30, 2001, Budapest, Hungary

CEENet has established in the last seven years through a series of workshops, a remarkable record of knowledge transfer through teaching in all forms (lectures, recitations, and laboratory exercises which provide the environment for hands on experience) the right institutions to Digitally Unite the countries of Central and Eastern Europe, Caucasus region and Central Asia. By exposing them to the basic principles of the network technology and Internet, the understanding of the global information infrastructure, the primary goal is to provide the structures for technological and managerial sustainability.
No effort will be spared to bring for a limited budget as many trainees as possible. In previous workshops this was a result of the rigorous cost control strategy and mechanism. For once, the lecturers are volunteers who
give their time, intelligence and knowledge well in advance of the actual workshop by devising the programme, and preparing lectures and labs. The number of the lecturers (6) is rather small compared to the number of trainees (32). The richly equipped lab, which is set up to enable numerous hands-on exercises, is rented free of charge by different vendors (mainly CISCO).
The NATO ANW Proceedings, from the previous CEENet workshops, have been published in the form of a book. Those books contain valuable materials, such as articles, lectures and presentations and will be used as a textbook during the present workshop. The books are distributed to all the trainees so reducing the cost of hand-outs. The copies of the proceedings are also presented to all the member countries of CEENet, and are sent to national technology workshops. Significant part of the training material is available on Web. Additional books of total value $30,000 are donated by O’Reilly and distributed among trainees.
In order to broaden the range of possibilities for the developing countries in CEE, FSU and CA, where due to the lack of communication infrastructure and availability of funds in the period of both political and economic transitions, a satellite provision of the Internet for the education and research community, is not usually an option, but only alternative. Hence, this year Workshop pays particular attention to the satellite technology, its symbiosis with the TCP/IP protocols, and the subtleties of running and Internet services for a large number of academic communities in different countries over a satellite link.
The objective of the course is to provide a sound technical background of the communication infrastructure needed to master and to establish global networking. It starts with the very short recapitulation of the basics such as serial communications, addressing (which are addressed in more detail during the six-week distance learning pre-course, used also for the preselection of candidates), and ends with system management, policy
routing, protocols and their usage, caching, quality of service and the prerequisites for multimedia and high-speed networking. Objective of the ANW

The objectives of the Workshop are:

  1. To train the students from CEE and FSU (including CA) on the fundamentals of the Internet and network technology by the well recognized international experts
  2. To combine the knowledge of networking technology and the Internet – which is the semantics, with the opportunities provided by many of the Network Infrastructure Grants (NIGs) – which is the syntax of communications
  3. To enumerate the necessary conditions, identify the technical level and structural organization, as well as to posit the required knowledge of the technology in order to achieve a technically feasible and sustainable network
  4. To create and foster the human network among the participants, which is later crucial in their respective problem solving environment xpected short term and long-term objectives of the ANW for Partner countries:
    1. To increase the level of the know-how with respect to network technology among the key people that will take part in running various networks and network operations
    2. To make them aware in the latest developments and the start of the art of the technology,
    3. Transfer of the teaching methods and practices from the developed countries to the developing ones Expected short term and long-term objectives of the ANW for the NATO countries
  5. Inducement of networking as a vehicle for convergence towards to NATO countries
  6. Proliferation of the CIT and thus an increase the possibilities for the identification of new markets
  7. Political stability in the regions of CEE and FSU through building the necessary communication infrastructure for a free flow of information and accessibility
CEENet Workshop on Network Policy, Issyk-Kul 2001

The workshop in Issyk-Kul was devoted to the support of Kyrgyz Research and Educational Network (KREN)

Since 1998, the construction of the Kyrgyz Research and Educational Network using high-tech infrastructure has been supported by the Scientific program of NATO. From the very beginning, Kyrgyzstan has supported the idea of the Virtual Silk Highway project and has actively participated in the preparation and realization of this international project. The project officially began in Issyk-Kul in September 2001 during an CEENet workshop on advanced computer networks. It is necessary to note that the Silk Highway project is an embodiment of ideas from the Doctrine “Diplomacy of the Silk Road,” established a precident for new information and communication technology. In 1999, the Doctrine established the logical and imperative necessity for the revival of the “Great Silk Road” on the qualitatively new basis of high tech communications. At the present stage, revival of the “Great Silk Road” allows for the transformation of this region into a zone of stability, safety, friendship, cooperation and equal partnership.

The Sixth CEENet Workshop in Network Technology, August 19-27, 2000, Budapest, Hungary

The dynamic and innovative nature of the CEENet Education with respect to the organization and the execution of the workshops in the areas of technology, management and policy was broaden and reinforced again during the Sixth CEENet Workshop on Network Technology held in Budapest from August 19 to August 27, 2000. This was particularly true for Track 1: Engineering the Network – NATO ANW, colored for the first time with two new features: a pre-workshop course in distance education and a series of lectures covering the cutting edge developments in the area of network protocols.

Building on the previous experience in distance education and learning, developed through the Track 3 – Wired Education, a group of key lecturers from the Engineering the Network track designed and implemented a pre-workshop curriculum that included fundamental issues, principles and methods to be learned by the participants in order to provide them with the essential knowledge required to gain basic understanding in network engineering, to improve the selection process for the face-to-face workshop in Budapest, as well as to offer the right environment for introducing more advanced topics for the actual workshop.

The results were indeed gratifying, as the analysis of the evaluation of the workshop by the lecturers and the students indicates, both in the very good quality of the Programme content carried out in Budapest and the students present at the workshop.

Lecturers and Lectures

The Fifth CEENet Workshop in Network Technology, August 17-25, 1999, Budapest, Hungary

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. JanGruntorad, by Professor Layos Balint in the name of Hungarnet, Dr. GaborFarcas 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.
The workshop (preceeded by the OSI summit) was attended by 105 studentsfrom 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-kindcontributions 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 CEENetGA 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 Fourth CEENet Workshop on Network Technology 22-30 August 1998, Bratislava, Czech Republic

Bratislava was the next stop for the CEENet Network Technology train.

Moreover, it was the place where CEENet education endeavor cross new frontiers and open new horizons with establishing a track which deals with the application of computing and communication technology into the realm of education.
The home of the Workshop was the Slovak Technical University, actually the Computer Science Department and the Computer Center. The workshop opened on August 22, 1998, at the Big Lecture Hall of the University, with the presence of Dr. Pavol Horvath, the Director of SANET, Mr. Jonathan Peizer, the Chief Information Technology Officer of Soros Foundation, Dr. Jean-Paul Nadreau, the NATO-Codirector of the Workshop and Vice-chancellor for research of the University of Quebec, Dr. Jacek Gajewski and Professor Dr. Oliver B. Popov, both from CEENet. They all gave short welcome speeches.
The form and the structure of the education system followed the establishedpattern since the very beginning of the workshops, comprised of three different types of activities: scientific lectures, the presentations given by the sponsors, and finally the free style evening lectures. Due to the large number of sponsors and the topics covered, very few of the evening lectures unlike the previous years, were devoted to the social and the cultural implications of the network technology. Professor Popov and Dr. Gajewski moderated all of the sponsor’s spotlights and evening lectures. Eighteen lecturers from fourteen different countries carried out the
Scientific Programme. Six more lecturers, who came from our sponsors, joined the CEENet team. For the first time, we had topics like Internet commerce, the concept of portals, robots, and distributed indexing, and security in RAS.Moreover, we had a complete new track termed as Wired Education. The track proved to be very successful one. For the execution of the programme for this track, our Nordic crew made up of lecturers from Estonia, Finland and Sweden was responsible.
There were a number of joint lectures for the three tracks. The Workshop guest of honor, Mr. Ed Kozel, from Cisco Systems, gave one of the most interesting and inspiring lectures. He talked about the profound changes in the telecommunication industry, the new Internet itself and the implications of these changes in CIT to all aspects of life.
The workshop academic endeavor, which means the Programme and thelecturers, was very highly evaluated. Indeed, the programme relevance, thequality of teaching and instruction, and the suitability and usefulness of the distributed materials, had higher grades then any of the workshops in the past.
 The addition of one more track meant new challenge for all of the people involved with the preparation of the workshop. As time went by, it became clear that the Wired Education track would have a very positive spill over into the other tracks. Programme was quite demanding and completely absorbing for most of the attendees, which also help to keep the vitality of the learning environment established during the very first workshop. The best students in each of the tracks, received Palm Pilot PDAs donated by the 3Com corporation. The gift from O’Reilly enabled us to distribute three hundred books among the attendees.
 The Workshop was financed by two grants: one from Soros Foundation and thesecond from the NATO Science Programme. Hence, we would like to express our deepest gratitude and sincere appreciation to Mr. Jonathan Peizer from theSoros Foundation and NATO Science Policy Committee for their continuossupport of the CEENet educational activities.
 SANET, the research and educational network of Slovakia and a member o fCEENet, provided the external connectivity. Our special thanks to Dr. Pavol Horvath, Mr. Jaroslav Bobovsky, and their associates for giving
crucial logistic assistance and hospitality. Many aspects of the workshoplogistics (eg. travel arrangments and ticket reimbursement, lecture textcollection) were dealt by the experienced team from Estonia: Mrs Anne
Mardimae and Mrs. Riina Reinumagi.
 We would like to extended our appreciation to all the lecturers and the attendees, sponsors and anyone who gave their time, shared their knowledge, and distributed the spirit of co-operation and collaboration through the CEENet Human Network.

Third CEENet Workshop on Network Technology, 24.8-1.9.1997, Zagreb, Croatia

The City of Zagreb was the home of the Third CEENet Workshop on NetworkTechnology which took place from August 24 until September 1, 1997. The two venues for the whole event were: the “Cvjetno” campus which provided room and board for the participants, and the Faculty of Electrical Engineering and Computer Science (FER) that housed the lectures, the recitations and the entire laboratory work.

 The workshop opened on August 24, 1997, at the Maximus Hall of the FER�with the presence of the Rector of the University of Zagreb, representatives of the Croatian Academic and Research Network (CARNet), the Soros Foundation, the attendees, and the lecturers. The series of welcome speeches was started by the Professor Lovrak, Vice-dean of FER, Mr. Predrag Pale, The Deputy Minister of Science and Technology of Croatia, Mr. Jonathan Peizer, the Chief Information Technology Officer of the Soros Foundation, Mr. Predrag Vidas, the CEO of CARNet, Dr. Jacek Gajewski, in the name of the Organizing Committee andCEENet, and Professor Oliver Popov, who spoke on behalf of the ProgrammeCommittee and lecturers. Mr. Vidas, actually delivered his speech by using the multimedia technology from the offices of CARNet, over a 625 Mbps ATM line. The opening ceremony proved to be an appropriate setting to promote the second publication by CEENet, a selection of the lectures delivered in Budapest, a book under the title “The Gateway to Cyberspace” and dedicated to the lecturers.
 Zagreb was the place where the Workshop received more attention then any previous one by both the printed and electronic press.The first press conference was with the speakers from the opening session. Indeed, during the whole week of the Workshop, Dr. Gajewski and Professor Popov gave numerous interviews to some of the major Croatian daily newspapers and magazines, radio and TV stations.
The workshop in Zagreb was made possible through a generous grant from theSoros Foundation and a donation by the Ministry of Science and Technology of Croatia which materialized in a free housing in the dormitory for all of the participants and reduced prices for the equipment, lecture halls, and laboratories.

The educational system of the Workshop was comprised from three different types of activities: the regular scientific program, the presentations given by the sponsors, and finally the evening lectures.

 1. The Programme of the Workshop and the Lecturers

  The Programme was significantly enriched this year with topics and areaspertinent to the latest in network technology. It was due in part to the infrastructure, the implementation of ATM on national basis, and the fact that CARNet relies heavily on the human and technical resources from FER. The basic topology of the Workshop network was already build and software installed, when the first lectures and organizers arrived in Zagreb. It was done by the CARNet technical team, led by Mr. Nevenko Bartolincic. They are to be commended for the outstanding job done before and during the Workshop.
 Joined by a couple of lecturers from CARNet, most of the CEENet ’96 team oflecturers, and lead by the experienced track leaders, Mr. Jauk and Mr Bogusz, was capable of carrying out the demanding programme listed below:

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.
