Abstract: Through analysis of representative Gossip protocol used in P2P streaming system, for its ignorance of its nodes and heterogeneous network of dynamic factors, this paper puts forward dynamic adaptive Gossip protocol which sorts the nodes through their ability, and fully takes advantages of the strong nodes. This protocol has a good feasibility and can reflect the dynamic of the nodes and resources in P2P network, to some extend, it can improve the efficiency of the overall system.

Key words: Gossip protocol, P2P streaming media, dynamic heterogeneous, adaptive, DONet model
