P2P流媒体系统中,减少ISP(Internet Service Provider)交叉流量是一个重要的研究方向,本文提出了一种减少ISP交叉流量的P2P流媒体方案,方案综合考虑了Pull机制、DHT(Distributed Hash Table,分布式哈希表)原理和IPv6地址的聚类特性,从网络拓扑构建和包调度机制两个方面,通过增加ISP内数据共享和减少ISP间数据请求的方式,减少P2P流媒体系统中的ISP交叉流量.仿真结果显示,在大规模系统中,该方案能够有效的减少ISP交叉流量.
P2P streaming media system, to reduce ISP (Internet Service Provider) cross-traffic is an important research direction, this paper proposes a P2P cross-traffic ISP streaming media solutions, the program takes into account the Pull mechanism, DHT (Distributed Hash Table, Distributed hash table) principle and the clustering characteristics of IPv6 address, from the aspects of network topology construction and packet scheduling mechanism, it can reduce ISP in P2P streaming media system by increasing the data sharing in ISP and reducing the data request among ISP Cross-flow simulation results show that in large-scale systems, this scheme can effectively reduce ISP cross traffic.
