摘要: 通过分析具有代表性的P2P流媒体系统中所使用的Gossip协议,针对其没有考虑节点和网络的动态异质性等因素,提出动态自适应Gossip协议,该协议采取对节点的能力度进行排序的方式,充分利用能力强的节点,具有良好的适应性,能够反映P2P网络中节点和资源的动态性,在一定程度上提高了系统的整体效率。

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
