PZP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.
PZP存儲繫統具有可擴展性好、容錯性高等優勢,是近年來學術界的研究熱點.但是由于P2P存儲繫統的複雜性高,搭建起來比較睏難,使得繫統併沒有隨著研究髮展而流行起來.尤其是在廣域網中,由于節點的高動態性,使得繫統的部署和維護更加睏難.介紹瞭一箇開放式的P2P存儲平檯架構,可以在封閉的機房繫統裏,利用穩定的服務器搭建存儲繫統,也可以在開放的廣域網環境下,利用動態性高的箇人電腦來搭建存儲繫統.上層應用開髮者可方便地使用該平檯來創建各種服務,從而能將P2P存儲繫統在實際應用中推廣開來.

Peer-to-peer(P2P)storage systems have been one of the hottest research topics for their attractive advantages,such as sealability 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.
