the Technion, Israel. His primary research interest is the
theory and application of management-related problems in IP
networks. Danny has published many papers and authored a book in
the area of computer networking. He served as the general chair of
Open Arch 2000, and as a TPC member for many conferences including
INFOCOM 2002-2003, Open Arch 2000-2001-2003, IM-NOMS 2001-2005, and
as an Editor in the Journal of Communications and Networks (JCN).
Arto Juhola has been with Technical Research Centre of
Finland since 2001. He manages the EU IST CONTEXT project
formed by Alex Galis. Arto has written largely red tape and
project proposal aspects, and has contributed to one conference
paper within the EU IST project.
Alex Galis is a Visiting Professor in the
Telecommunications Systems Research Group of the Department of
Electronic and Electrical Engineering, University College London.
He is the author and co-author of more that 125 papers and
technical reports and 4 books in the areas of programmable networks
and services, selfware and autonomic management, context sensitive
communications, programmable GRIDs and ambient networks.
Joan Serrat-Fernandez has worked at Universitat
Politecnica de Catalunya since 1977. Recently, he has participated
in the IST-FAIN, IST-WINMAN and IST-CONTEXT, three EU projects
dealing with management of active networks, IP/WDM and context
aware services respectively. Prof. Serrat is a contributor in
technical, scientific fora and magazines. He is also
co-author/co-editor of four technical books.
