【摘要】 P2P存储系统具有可扩展性好、容错性高等优势,是近年来学术界的研究热点.但是由于P2P存储系统的复杂性高,搭建起来比较困难,使得系统并没有随着研究发展而流行起来.尤其是在广域网中,由于节点的高动态性,使得系统的部署和维护更加困难.介绍了一个开放式的P2P存储平台架构,可以在封闭的机房系统里,利用稳定的服务器搭建存储系统,也可以在开放的广域网环境下,利用动态性高的个人电脑来搭建存储系统.上层应用开发者可方便地使用该平台来创建各种服务,从而能将P2P存储系统在实际应用中推广开来.更多还原

【Abstract】 Peer-to-peer(P2P) storage systems have been one of the hottest research topics for their attractive advantages,such as scalability and fault tolerance.However,because of the complexity of building a P2P storage system,applications don’t spread as widely as researches,especially in the WAN.It is hard to deploy and maintain a P2P storage system due to the high dynamics of peers.The architecture of an open P2P storage platform is designed.It can be a closed system built in data center,using steady servers;and it can be also an open system built in WAN,using high dynamic peers such as personal computers.Any developer can use this platform conveniently to support his own services,and the platform pushes application development of P2P storage systems.更多还原
