摘要
非结构化的P2P系统,进行资源查找定位时采用“洪泛”方法,这不仅限制了资源搜索的效率和系统的可扩展性,而且也给网络带来了额外的负担。为了提高系统性能,提出了一种建立在分层结构基础上的基于分类检索的自聚簇P2P系统(ACP2P),并实现其原形系统。数据包级的网络模拟实验表明,系统能有效地提高资源定位的效率,显著改善自身的可扩展性。
Unstructured Peer-to-Peer network uses flooding algorithm to route searching messages which not only brings unnecessary expenditure of network bandwidth, but also limits the rate of resource searching and expandability of P2P system. In order to decrease the influence of this problem, this paper presented a new auto-clustering Peer-to-Peer system （ACP2P） based on classification search, and implemented the archetype of this system. The experiments using network simulator based on data packets show that the system can increase the rate of resource searching and expandability effectively.
