摘要 研究P2P流媒体点播中普遍存在的启动时间长、传输抖动大的问题,提出了1种基于簇缓存的节点选择策略。通过在簇内缓存节点的查询记录和部分媒体块,并在带宽优先的基础上,结合节点寿命进行资源节点选择,降低播放抖动率。仿真实例说明了该策略的有效性。 Considering the long start-up delay and large transmission jitter in P2P on-demand streaming media, Cluster Cache based Peer Selection Strategy（CCPSS） is proposed. First the peers＇ lookup records and the part of media blocks are cached, then based on bandwidth priority as well as node life, the resource peers are selected to decline start-up delay and the playback jitter rate. Simulation results show the validity of the proposed strategy.
