As a collaborative network for distribution of multimedia streams to a potentially large number of hosts, P2P networking relays on efficient application layer multicast distribution services. As for centralized streaming application, delivery constraints are also stringent requirements for P2P networks in order to prevent playback glitches or service interruption. Because of it's nature, P2P nods that built up the overlay network are free to join and leave the service at any time with or without any notification to other nodes. This situation drives to a critical environment that should ensure dynamicity management of the distribution processes in order to ensure smooth play back rate to clients during streaming sessions. To prevent service interruption a robust and adaptive mechanism to manage such changes is needed. In this paper we analyze existing P2P construction protocols and propose a multicast gossip protocol to ensure network response to its sudden changes.
