摘要
P2P(peer-to-peer)模式是互联网的重要应用之一,资源定位是实现P2P网络资源共享的前提条件。本文首先介绍国内外P2P资源定位的研究现状,接着介绍了P2P网络的四种模型,然后介绍目前P2P资源定位的一些方法以及对这些方法的优化,如泛洪、随机漫步、基于分布式哈希表的查找等。
P2P（peer-to-peer） mode is one of the important applications of the Internet.Resource Locating is prerequisite of implementation sharing P2P network resources.In this paper,we introduce research status of P2P resources locating in our country and abroad,then introduce four models of the P2P networks,finally introduce the current some methods of P2P resource locating and the optimization of these methods,such as floodplains,random walk,research based on distributed hash Table.
