Solution Provider companies (like IBM, Cisco and others) proposed and implemented number of methods to cure the continuing problems of WEB service performance degradation, which can be characterised as network transport bottlenecks and WEB server weaknesses.
We briefly outline such new buzzwords such as ‘Content Routing’, ‘Content Switching’,
‘Content Edge delivery’ or ‘Internet vs. Enterprise CDN’, and point out how those can be used to implement scalable, cost effective, safe, reliable fast and user friendly WEB infrastructure - to satisfy the ever-growing demand of information hungry customers.
Finally, we give a concise information about IBM Hungary’s offering in the field of Content Delivery Networking.

In the lecture I would like to give an overview of the last 10 years concerning the network development and the challenges of local infrastructure. In spite of the effort the Institute made during the last 5 years to increase the level of the infrastructure, the devices serving the research and education are not satisfying the requirements of the digital age. On the other hand, with the developments that had been made so far, the quality of the data transfer and the management of the working system has been definitely improved. Our aim in the future involves the possibility of further technical development and better integration to the existing education and research networks.
Introducing the Internet technology brought a lot of changes in our college as well. It has been materialised especially in gaining and transferring information and in the development of contacts between institutes and individuals (lecturers and students as well). A number of fruitful contacts has been formed with foreign colleges particularly in computer aided education and in e-Leaming as well. More and more courses apply Internet services in a direct or indirect way.
In the lecture I am going to give an image of our technical developments in the near future and I would also like to sketch our long-term plans.

The bandwidth of the HBONE/Intemet connection of the university has grown to 2.5 Gbps in the last year. Since the traffic between the university’s campuses has grown greatly, it became necessary to improve the university network from 100/155 Mbps to the range of Gbps.
The raised bandwidth, the viruses and the attacks recognised in the latest times made it necessary to set up a firewall that protects the whole university network. The firewall between the router HBONE and the university MAN is an IBM Firewall software that runs on an IBM RS/6000 server. Although it has gigabit interfaces, because of the amount of CPU usage and the complex rules, we experienced that the speed of the Internet connection of the institution is getting worse and worse.
The traffic of the inner backbone is ensured by the Cisco Catalyst 6506 router placed in the centre, the Cisco Catalyst 3550 routers placed in the campuses and the gigabit interfaced L3 switches. The connections between the campuses are handled by more than a dozen relay having capability of L4 filtering. The load of these tools is low - according to our experiences - in spite of the grown traffic. It made it possible to place the defence system needed by the firewall closer to the destination networks that is the filtering is done by the switches ensuring the connection of the campuses. This way the firewall protects the UDNet network against the attacks from the Internet not only at one point, but also in a distributed way at each campus.
This mechanism significantly reduced the load of the former singular firewall since it protects only the equipment of the backbone of the institution. So the throughput of the server improves a lot and lets the regional router HBONE accessed with almost 1 Gbps. Furthermore the distributed firewall system ensures a greater security for the campuses, since it filters not only attacks from the Internet, but the attacks may coming from other campuses.
The lecture will cover the practical experiences gained from the firewall system consisting of more than a dozen Gbps capacity Cisco L3 switches. Moreover, we will talk about the expansion philosophy, and the technical details of the institution’s Gigabit backbone protected by a firewall system. The shown experiences make other institutions capable to handle the critical defence problems relating the unavoidable expansion of the backbone equipment in an efficient way.
Effects on Hungarian e-content, due to the Hungarian W3C Office

The World Wide Web Consortium (W3C) launches its Hungarian Office based at the Department of Distributed Systems of the Computer and Automation Research Institute of the Hungarian Academy of Sciences (MTA SZTAKI, DSD) in Budapest, Hungary, on 24 September 2002.
The W3C was created to lead the Web to its full potential by developing common protocols that promote its evolution and ensure its interoperability. It is an international industry consortium jointly run by the MIT LCS in the USA, the ERCIM in France and Keio University in Japan.
The Hungarian Office is the first office in Central Europe, joining an active roster, which includes a number of European Offices of W3C as well as the W3C European host site at ERCIM in France.
The goals of W3C Offices are to promote efforts in local languages, help broaden W3C’s geographical base, and encourage international participation in W3C Activities. So the main tasks of the Hungarian Office are to make the W3C technologies known and popular in Hungary through various events, workshops, presentations; translate W3C News and W3C documents; help the Hungarian organisations to join to the W3C Activities.
This presentation will be a summary of the activities of W3C Hungarian Office and will be about the necessary organisational and R&D activities for creating the Hungarian e-content and steps for developing the infrastructure of the Academic community.
