基于资源路由表的P2P改进模型

摘要

许多非结构化P2P网络如Gnutella采用的"洪泛"广播机制造成了严重的网络拥塞,降低资源定位的效能,增加网络流量.针对该问题,在现有P2P技术的基础上结合传统的客户-服务器结构构造一个混合P2P模型,提出一种基于资源路由表的路由算法,并对该算法进行分析.仿真结果显示,该模型能够有效地减小P2P系统的网络流量,缩短响应时延.%“Flooding” used by many unstructured P2P networks such as Gnutella brings about extremely high traffic and locating delay.Aiming at the problem, this paper structures a mixed P2P model which combines P2P and client-server, proposes a routing algorithm based on resource routing table and describes it in detail.Simulation result shows the model can reduce traffic and shorten response delay.
