He also was a research engineer in the Research Unit in Networking (RUN) of the University of Liege, Belgium, from 1993 to 1995.

He graduated in electrical engineering from the University of Liege, Belgium, in June 1993, and was awarded his Ph.D. in Computer Science from Lancaster University, England, in January 2000.

His research interest includes multimedia content distribution, overlay network (including peer-to-peer and application-level multicast), dependable networks, traffic control and engineering and router architectures.

He has many refereed publications in the field and has served on several programme committees of international conferences. He was the recipient of the “Young Researcher Award” at CFIP’99.

David Hutchison is Professor of Computing at Lancaster University and has worked in the areas of computer communications and distributed systems for more than 20 years. He has completed many UK and European funded research contracts and published many papers as well as writing and editing books in these areas.

He is an expert evaluator and reviewer for the European Commission in the areas of communications and networking, has represented the UK on the management committee of the COST264 project on Multimedia Group Communication, and the COST263 project on Quality of Future Internet Services, and is now a member of the steering group of the recently started IST FP6 Network of Excellence on Emerging Networking Technologies and Experiments (E-NEXT).

His research interests cover architecture, services and communication protocols for distributed multimedia systems, including Quality of Service (QoS) mechanisms, programmable networking and also multimedia content distribution networks. He participates in several UK and European collaborative projects, in which an integrating theme is QoS for multimedia communications. He is a programme committee member for many international conferences and workshops, and is a member of the editorial board of the ACM Multimedia Systems Journal, Computer Networks, and Computer Communications. He is Editor of the Wiley book series in Communications Networking and Distributed Systems. As of 2004, he is an editor of the Springer-Verlag LNCS Series, and is responsible for the area of Computer Communication Networks and Telecommunications.

Thomas Plagemann received his Diploma in Computer Science from the University Erlangen-Nurnberg (Germany) in 1990, and his Doctor of Technical Science from Swiss Federal Institute of Technology (ETH) Zurich (Switzerland) in 1994. In 1995, he was honoured with the Medal of the ETH Zurich for his doctoral thesis, in which he developed the DaCaPo communication subsystem. From 1994 to 1996 Thomas Plagemann was a researcher at UniK––Center of Technology at Kjeller and Telenor R&D (Norway). Since 1996, Thomas Plagemann is Professor at the University of Oslo. His research interests include multimedia middleware, protocol architectures, QoS, operating system support for distributed multimedia systems, content distribution infrastructures, and interactive distance learning.

Peter Steenkiste is a Professor of Computer Science and of Electrical and Computer Engineering at Carnegie Mellon University. He received the degree of Electrical Engineer from the University of Gent in Belgium in 1982, and the M.S. and Ph.D. degrees in Electrical Engineering from Stanford University in 1983 and 1987, respectively.

His research interests are in the areas of networking and distributed computing. While at CMU, he worked on Nectar, the first workstation clusters built around a high-performance, switch-based local area network. He contributed both to the optimization of the communication subsystem and to the development of programming tools for workstation clusters. The optimization of application-level communication performance over commodity networks was further explored in the Gigabit Nectar and Credit Net projects. All these projects developed prototype systems that were used by a wide range of application groups, allowing a realistic evaluation of the research. His current research is in the areas of network services and pervasive computing. One of the current challenges in today’s Internet is how to delivery high quality, sophisticated services to applications in a scalable fashion. The Libra project is developing techniques for runtime adaptation of services in response to changing resource availability and user needs. He is also active in pervasive computing in the context of the CMU Aura project. The goal of Aura is to create a distraction-free pervasive computing environment that proactively helps users with daily tasks. In Aura, his research focus is on supporting adaptive and proactive applications, wireless networks, and device-rich spaces.

He is a member of the ACM and a senior member of the IEEE. He has been on a number of program committees and he was co-chair for the OPENSIG’99 workshop and the Eighth “International Workshop on Quality of Service” (IWQOS’00). He was also program chair for HPDC’2000 and general co-chair for ACM SIGCOMM’02. He was an associated editor for IEEE Transactions on Parallel and Distributed Systems (1998–1999) and he is currently on the editorial board of “IEEE/ACM Transactions on Networking”, “Cluster Computing”, and the “Journal of Grid Computing”.
