摘　　要：针对Gossip协议数据传播随机性与不确定性问题,提出了一种混合结构方式。该方式将非结构化P2P网络和结构化P2P网络相结合,通过增加数据片预取调度算法,弥补了Gossip协议数据传输的随意性。实验结果表明,此方式提高了节点成功播放率,降低了系统开销。The Gossip-based P2P streaming media system has become the mainstream of P2P streaming media systems. But the inherent drawbacks of Gossip protocol--the randomness and uncertainties of data dissemination influence the P2P streaming media system. Based on the Gossip, an approach combining unstructured and structured P2P network was proposed to cover the shortage of the data dissemination based on Gossip and improve the efficiency of streaming media system. Finally the approach has been proved to be reliable through simulation.
