摘要
Peer-to-Peer(P2P)方式是对客户机/服务器模式的一种突破。P2P网络具有的可扩展性好,健壮性,充分利用分布资源等特性使其可以被广泛应用于文件共享,分布式计算等领域。资源定位是P2P应用的一个核心问题。在分析了P2P资源定位协议Chord的性能后,提出了对Chord的改进。通过增加查询的跨度和finger列表的长度,减少查询节点的跳数,从而降低查询路径的长度。实验证明,改进的方法有效地减少了查询的开销,提高查询效率。
Network base on Peer-to-Peer breaks the traditional model of Client/Server.P2P network has characters such as good extension, robustness, use distributed resources sufficiently. It can be applied in file sharing, distributed computing. Resource location is a core problem of P2P application. After analyzing the original Chord＂ s performance, the paper give an algorithm to improve on the efficiency of query which increase query＇s span and the size of finger table to decrease the hops of query and reduce the path length of query. The simulation result shows that the algorithm is effective.
