The Scope

P2P2007 is the seventh in a series of annual conferences concerned with overlay network technologies. Overlay networks combine and share the resources owned by devices that are distributed around the Internet, which are normally relegated to the role of clients. Examples of such technologies include Peer-to-Peer Systems and Grids, but in general, any large-scale distributed system characterized by decentralization and sharing of resources can benefit from an overlay-based approach.

Recently, interesting applications of P2P technology have begun to emerge, together with new platforms for application development. We invite papers that reflect experience with practical applications of the current state of the art, or that explore new application areas. We are particularly interested in real, large-scale, deployed applications, rather than "toy" examples composed of a few nodes. The key issues to be considered are scalability, robustness, and security; we believe that these aspects are fundamental issues that must be solved before (legal) peer-to-peer and grid services will become mainstream.

Consistent with the previous occurrences of this conference, we would like to promote collaboration in research among academic institutions, government organizations, and business enterprises that are concerned with the research and implementation of peer-to-peer networks, grids, and large scale distributedsystems.

Update: Selected papers from the conference will be published in "Peer-to-Peer Networking and Applications" (Springer).


Any topic that relates to peer-to-peer systems, grids, and large-scale distributed systems or overlay networks is open for consideration. We would like to give special encouragement to experience reports with applications, with particular emphasis to those that treat problems related to scalability, robustness and security. Topics of interest for the conference include, but are not limited to:
  • P2P applications and services

  • Industrial applications / P2P in use

  • Security in P2P systems

  • Performance and robustness of P2P systems

  • Self-organization in P2P systems

  • P2P Information retrieval

  • Higher-level query support in P2P systems

  • Semantic overlay networks and semantic query routing in P2P systems

  • Trust and reputation management in P2P systems

  • Overlay architectures and topologies

  • Social networks

  • P2P Systems over MANETs

  • Delay Tolerant P2P systems

  • P2P economics

  • Cooperation in P2P systems

  • P2P workload characterization and simulation

  • P2P grids

All papers will have at least 3 expert reviews. The proceedings hardcopy will be available at the Conference.

Industry Track

We are especially interested in experience with practical, large-scale,
industrial, deployed applications. Therefore P2P 2007 is going to set up a
special industry track in its programme. Please indicate in a separate email
to the industrial liason chair ( if you wish
your submitted paper to be considered into an industry track.

Demo Proposals

P2P 2007 is encouraging the P2P community to demonstrate their
latest system developments and P2P applications at the P2P 2007
conference site. In addition to the demo presentation announced in
the official conference programme, a two page abstract will be published
in the proceedings.
