List of Participants


One of the major challenges of emerging networks (fixed and mobile) lies in the flexible creation and rapid deployment of a large variety of existing and newly emerging services. However, existing networks are highly inflexible and do not easily allow for the provisioning of new services. This explains why novel and useful services are not appearing more rapidly. Examples are multicast services, security, accounting and charging services, Quality of Service support and the like.

An attractive vision is to make future networks programmable in the same way that computers are programmable today. This calls for a stronger convergence of computing, storage and communication within networks.

One of the goals of this Dagstuhl seminar is to assess the state of the art in active and programmable networks. It is planned to evaluate how this current technology supports rapid service creation for a diversity of services and applications. In this context, positive and negative experiences in applying active and programmable networking technology need to be addressed. Ultimately, a research agenda for future research in this area should be one important outcome of this seminar.

The seminar will bring together researchers and engineers who have gained experience in different aspects of active and programmable networks.

Areas of interest include the following:

  • Experiences with prototypes and testbeds
  • Dynamically deployable services
  • Service location and description
  • QoS support mechanisms
  • Congestion control and traffic engineering
  • Multicast and group communication services
  • Applications of active networks
  • Active networking architectures
  • Accounting and charging
  • Safety and security
  • Active signaling
  • Transition strategies
  • Interaction of mobile agents and active networks
  • Evaluation criteria and performance measures


In the series Dagstuhl Reports each Dagstuhl Seminar and Dagstuhl Perspectives Workshop is documented. The seminar organizers, in cooperation with the collector, prepare a report that includes contributions from the participants' talks together with a summary of the seminar.

Dagstuhl's Impact

Please inform us when a publication was published as a result from your seminar. These publications are listed in the category Dagstuhl's Impact and are presented on a special shelf on the ground floor of the library.


Furthermore, a comprehensive peer-reviewed collection of research papers can be published in the series Dagstuhl Follow-Ups.
