不同P2P网络拓扑结构下的检索机制研究

A Study on Retrieval Method in Different P2P Network Topology

根据P2P网络的拓扑结构进行分类研究,着重针对中心化拓扑、全分布式非结构化拓扑、半分布式拓扑和全分布式拓扑4种结构及其检索机制进行概述、综合分析和比较研究,并提出P2P系统目前面临的主要问题及其发展趋势。

This paper studies the topologies of different P2P network, summarizes, analyses and compares of four P2P topologies and their information retrieval mechanism： centralized topology, decentralized unstructured topology, decentralized structured topology and partially decentralized topology. At the end, the paper comes up with the main problems P2P system be faced with, and its development trend.
