Chair Karel Vietsch, TERENA
The future architecture and governance of the Internet is steered by a number of worldwide organisations. The Internet Society is a professional membership society addressing issues that confront the future of the Internet. It is the organisational home for the Internet Engineering Task Force (IETF), which is the principal body engaged in the development of new Internet standard specifications. The Internet Corporation for Assigned Names and Numbers (ICANN) is the organisation that was formed to assume responsibility for IP address space allocation, protocol parameter assignment, domain name system management and root server management. At the European level, the policies designed and implemented by the European Commission, for example in the eEurope Action Plan and in the Framework Programmes, influence the development and use of the Internet. This session will present an update on the policies and actions of these four important bodies.

Session 1C Security
Chair Shirley Wood, UKERNA, United Kingdom
The Internet has grown significantly in the last ten years and we have come to rely on the Internet being available for the business functions of our institutions whenever we need to use it. As a result, network security is becoming more important all the time. In the late 1980's, users of the Internet experienced the early viruses and worms and, as a result of such threats, useful advice was given to those operating the network. More than ten years later, have we progressed in the area of security or are we still making the same simple mistakes, which allow viruses and worms to infiltrate our systems and disrupt our businesses? This session will seek to answer some of these fundamental questions.

Plenary 2 The Technology Plenary
Chair François Fluckiger, CERN, Switzerland
Networking Architecture in the 21st century

Over the past two decades, the architecture of networking was described through reference frameworks, which tried to reflect a complex and evolving reality. As we enter a new century, the time is ripe to revisit the relevance of these frameworks and to consider the impact of real components, sometimes neglected by architectural models, on existing and future networks infrastructures.

In particular, today's network infrastructure relies heavily on middleware layers, and especially on overlay networks (for name and directory services, multicasting, security, and content-oriented services). This session addresses these issues and discusses how middleware does and will impact the infrastructure and the host stacks. It will then discuss the architecture of the transport network itself, focusing on the status and trends of routing and the interplay of different technologies for various purposes. Indeed, it will be argued that engineering a real network such as a backbone should be goal-oriented, selecting the appropriate components from a portfolio of building blocks, themselves organised in a logical architecture.

The session features two of the most respected senior experts in the field, Brian Carpenter, former chairman of the IAB and Fred Baker, former chairman of the IETF.

Session 2A Middleware PKI
Chair Michael Gettes, Georgetown University, United States of America
Public Key Infrastructure (PKI) continues to be seen as a technology to resolve authentication and authorisation issues in our electronic world. Yet, even today, PKI technologies are riddled with policy and technical issues that limit their adoption. In this session we will learn about new PKI solutions and hear about the progress of PKI deployments.

Session 2B Multimedia Architecture
Chair Shirley Wood, UKERNA, United Kingdom
The Internet was originally used for transferring large files to large computers to be processed, and for sending email to colleagues. The introduction of graphical interfaces to applications, especially the Web, has caused a dramatic increase in the size and the usage of the network. Users now expect to interact with the Internet in the same way as they would with their digital televisions and this has led to the use of multimedia over the Internet. This session will be looking at several different multimedia architectures being used on the Internet and the implications of their use.

Session 2C End-to-end
Chair Jean-Paul le Guigner, CRU, France
Users from the education and research communities are more and more dependent on the Internet for their day-to-day work. Efficient collaboration through innovative usage such as Grid computing, videoconferencing, and distributed applications require good end-to-end performance, easy connectivity and smooth operation. However the intrinsic distributed nature of the Internet, without end-to-end governance or even global vision on the coherence and performance of the different infrastructures, the seriousness of management, the enforcement of security and the stability of application protocols makes it difficult to have a seamless service between users around the world.

Among the different stumbling stones paving the way before us when travelling the Internet, one can easily extract a subset of major well-known ones considered to be a "pain in the neck" by the users:

  • hard-to-cross firewalls implementing too much security from the users' perspective, although too little from the administrators',
  • non-global and untrustworthy authentication due to a deficit of coordination in the PKI area, address translation facilities (NAT), and different addressing or naming problems that can occur,
  • slow "last mile" bandwidth and poor performance from equipment,
  • legal issues (law enforcement), or even telecom regulations,
  • lack of standards for real distributed applications.
The e2e session will ingenuously reveal why things do not work as they should by raising the issues and expectations forming the basis for the debate that follows.

Panel: Harald Alvestrand, Brian Carpenter, Jon Crowcroft, Dietmar Erwin, François Fluckiger, Daniel Karrenberg and Lawrence Lessig

Session 3B Network Management
Chair Theodoros Karounos, GRNET, Greece
IP networks have evolved deploying a complete set of protocols and applications suitable for delivering best effort traffic. Despite the fact that the philosophy of IP networks was connectionless and up to now QoS was not supported, IP Management Systems provide complete monitoring of service provisioning, fault and performance data collection. Nowadays, IP networks support a diverse range of services,including VPNs, extranets, application hosting, ecommerce as well as voice and video traffic, and the range of services is growing daily. These new IP services demand more and more network resources. Network resources have become more valuable and need to be managed efficiently to deliver maximum performance. That is why new management frameworks are being developed to cope with this problem.

Session 5A DataGRID: Where are we?
Chair François Fluckiger, CERN, Switzerland
The DataGrid project aims at developing, deploying and testing a suite of Grid technologies to form a prototype infrastructure for LHC computing (LHC is the new accelerator under construction at CERN, Geneva) and other applied sciences (bio-informatics and earth observation). In particular the requirements of LHC computing are several orders of magnitude more stringent than any other past networking and computing undertaking.

The session will discuss the networking challenges the project is facing, and will present what has been achieved so far in terms of development and deployment, what difficulties where encountered and what partial lessons can already be drawn. This will be illustrated by the case of a specific experiment, ALICE, which will take over 10 years and includes an unprecedented volume of data (3-4 PB/year) to be concurrently analyzed by hundreds of physicists over the world.

Chair Roman Tirler, DG Information Society, European Commission
In the Grid, resources are almost all shared, including the network. To exploit the availability of distributed resources in a Grid setting and to allow application writers and application users to make some choices at run-time, a resource-scheduling environment needs to be developed and implemented. Grid-based virtual laboratories and science portals offer scientists remote experiment control, data management facilities and access to distributed resources by providing cross-institutional integration of information and resources in a familiar environment.
