摘要
对等网(Peer-to-Peer,简称P2P)技术是21世纪的技术热点之一。P2P的出现将互联网的存储模式由以前的"内容位于中心"模式转变为"内容位于边缘"模式,正适应了宽带互联网和更稳定、更高性能的个人电脑的现状,使得个人电脑重新焕发活力,大大提高了网络资源的利用率。目前P2P在文件共享、协同工作、对等计算、搜索引擎、电子商务、在线游戏,即时通信等方面的应用越来越广泛,并显示了良好的应用前景。分布式存储以其低成本、容错性强、易于管理、安全性等特性一直受到业界的青睐。由于P2P网络的发展,基于P2P的分布式存储系统也应运而生并以极大的速度发展。
P2P is one of the hottest technologies in 21st century. It makes the storage - mode of Internet change from ＂content as center＂ to＂ content as edge＂, and meets the broadband Internet and more steady, more high - performance PC. Because of P2P, PC radiates vigor again, and network resource is used fully. Presently, P2P has been already researched in the field of file - sharing, coordination working, reciprocity calculating,search engine, e - commerce, game on line, instant messaging, etc. It has obtained certain achievement. P2P has shown good prospect. The distributed storage system is always popular by the trade circle for its low cost price, permission of mistakes, easy management, and security and so on. Since P2P＇s electric network development, the distributed storage system based on the P2P emerges as the times require and develops as a high speed.
