This volume contains the proceedings of the 7th International Working Conference on Active and
Programmable Networks (IWAN 2005) that was held during November 21-23 2005 in Sophia
Antipolis Cote d' Azur France jointly organized by Hitachi Europe and INRIA. IWAN 2005 took
place against a backdrop of questions about the viability and - cessity of a conference that
deals with an area perceived by many as having run its full course. The Organizing Committee
during the preparations of the conference took these concerns seriously and reflected them in
the theme of this year's event entitled Re-incarnating Active Networking Research and
expanding the scope of past calls for papers into topics that have emerged from active and
programmable networks. The result was a success because we received 72 submissions a number
that - ceeded our expectations and in fact is one of the highest in the history of the conf-
ence. The distinguished Technical Program Committee set high standards for the final program
each one of the submitted papers received three peer reviews with detailed comments and
suggestions for the authors. In total 13 papers were accepted for the main program sessions
with 9 papers accepted unconditionally and the remaining 4 papers being conditionally accepted
with shepherding by selected Program Committee members.
