Peer selection strategies without overlay topology information in P2P streaming media
P2P流媒体中未知覆盖网拓扑信息的节点选择策略*

In order to select the efficient cooperative peers in the highly dynamic topology P2P network,this paper detected AS with the idea of using a similar route method.It substituted the full topology information of the known AS with the AS information where peer located. As well as combined the strategy of the smallest number of hops to select peers. In addition to the excellence of the peer and the aggregate flow rate to choose the best peer or peer-set as the supply of new peers added. And it solved the minimum-hop candidate peers with the same priority issues. Simulation results show that in the improved strategies the network congestion has been reduced and the quality of the streaming service has been significantly improved compared with the previous strategies.
