摘    要:资源的有效确定是P2P网络研究中一个关键问题。针对基本Chord和双向查询Chord路由算法存在路由表有较多冗余信息、没有考虑节点异构性的问题,该文通过对路由表冗余信息的改进,提出一种基于节点异构的双向查询Chord系统。实验结果表明,该系统减少了平均路由跳数,提高了资源查询效率。

关 键 词:P2P网络  基本Chord  双向查询  路由

Abstract:It is a key issue to locate resources effectively in P2P network research.The routing tables of the basic Chord algorithm and the bidirectional Chord algorithm have the problems of information redundancy and regardless of peers' heterogeneity.According to the bidirectional Chord algorithm,this paper proposes a bidirectional Chord system based on different peers by considering the heterogeneity of peers and the improvement of information redundancy in the routing tables.Experimental results indicate that the...
Keywords:P2P network  basic Chord  bidirectional search  routing
