一种非结构P2P网络的搜索方法

A search method for unstructured P2P networks

随着近年来许多P2P系统的出现,P2P技术逐渐成为人们研究的热点。P2P技术是基于一种对等的思想,目的是使网络中各用户之间能够自由的通信。目前技术主要应用在文件共享,分布式计算,协作系统,电子商务和以P2P为基础的深度搜索引擎等方面。其中如何高效地搜索P2P网络上的资源是P2P网络实现的最关键的问题。在对现有网络基本搜索方法的研究中,分析了许多改进的搜索方法,包括基于转发的改进,基于缓存的改进和基于覆盖网络拓扑结构的改进方法,在此基础上提出一种相对高效的搜索方法。

With the emergence of many P2P systems m recent years The P2P technique is based on the equal thought and its arm to organize all users in the network to communicate freely. Now the P2P technique is mainly applied to the file shared, distributed calculation, cooperating systems, electronic commerce and search engine. How to search the resources in the P2P networks efficiently is the key problem when the P2P networks are developed. The basic search methods including forwarding-based approaches, cache-based approaches and overlay topology optimization are analyzed and a new improved more efficient search method is presented.
