Engineering the Network . The Seventh CEENet Workshop on Network Technology Location (site and country): CEU Conference Centre H-1106 Budapest, Kerepesi ut 87, Hungary Dates: August, 20 . 30, 2001 Number of working days: 6 full- and 2 half-days Keywords (maximum 15): VSAT Technology, Flow Control and Congestion Routing, Multicasting, Regional Network Management, Caching, Mobile Networking The Scientific Programme of the workshop ======================================== The Internet and networking in general have a profound influence on all aspects of our everyday life. The Digital Age, which has created the principal technological foundations for networking from anywhere to everywhere and by everyone, is characterized by the constant transformation in the way we perceive, use and work with communication and computing, education and research, culture and social relations, consumer electronics and entertainment, broadcasting and publishing. The notion of integration and totality of information in all of these activities is what creates the phenomena of convergence and inevitability. The technology considerations are complex and knowledge intensive, and in order to master them and gain the necessary amount of expertise, one has to have an essential understanding of both communication and computing, as well as the proper engineering skills and the consequences and the implications of design and decision making, and a will to constantly pursue the myriad of the innovations and changes that are appearing almost daily. 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: http://www.ceenet.org/workshops. 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 Expected 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) Will 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 (1) Inducement of networking as a vehicle for convergence towards to NATO countries (2) Proliferation of the CIT and thus an increase the possibilities for the identification of new markets (3) Political stability in the regions of CEE and FSU through building the necessary communication infrastructure for a free flow of information and accessibility Schedule of the workshop ======================== Oth day (Monday, Aug 20th) Arrivals, Registration. 1st day (Tuesday, Aug, 21st) a.m. Arrivals Registration p.m. Opening ceremony Introduction to the workshop programme Instruction on usage of labs and computer equipment Serial communications - - recapitulation of distance learning pre-course, using laboratory equipment.
