Virtual overlay networks, such as virtual private networks or peer-to-peer services, can be seen as a new paradigm for providing multi-service networks. Virtual overlay networks may offer customized services to a specified community while providing a high degree of flexibility in the usage of shared resources. This paper examines the requirements of operating dynamic overlays, in particular, for peer-to-peer services. The analysis is based on extensive measurement studies performed on the

As an enabling infrastructure to implement a distributed control scheme for p2p overlays a so-called Application-Layer Active Networking (ALAN) platform has been chosen. Based on Application-Layer Active Networking, Active Virtual Peers (AVP) are introduced as the main concept for dynamic operation and management of peer-to-peer overlay networks. AVPs facilitate policy enforcement or performance management by means of self-organization, predominantly on the application layer with minimum interference on lower layers.
