摘　　要：根据IP地址的特性,提出一种节点间静态测距法.同时考虑节点内容的相似性、网络节点位置、稳定性、传输能力等因素,根据节点数据的传输时延的特点,提出一种选择服务节点的算法.经实验和仿真证明,文中所提的节点选择机制能较大提高P2P流媒体系统性能,优化系统路由.Based on the characteristics of IP address, this paper proposes an algorithm which can statically measure inter-peer distance. And considering these factors such as coherence of peer contents, the locality of peer, stability and transmission capacity, we propose an algorithm of choosing service node based on the characteristic of data transmission delay of inter-peer. Simulation results show that our algorithm can enhance performance of P2 P system and optimize the routing of P2 P system.
