摘　　要： P2P存储系统以功能对等的方式组成存储网络,面向服务的体系结构为存储资源的有效管理以及按需服务的实现提供了一种思路。提出的P2P存储系统模型采用分层思想,建立在结构化覆盖网络之上,将异构节点存储资源封装成服务块,以用户需求为出发点,通过服务的动态选取和组合,形成可定制的个人存储视图,并给出一种对等节点的功能部署结构。模型达到分散控制,具有良好的可扩展性。 P2P storage system is organized in a peer-to-peer way. Service-oriented architecture is an idea to provide effective storage resources management and service on demand. The P2P storage system model presented is constructed on structured overlay network using layer mechanism. Storage resources on heterogeneous nodes are encapsulated in service blocks. Individual storage view can be customized from users＇ point by dynamic choice and combination of services. In addition, deployment of layers in peer is also described. This model is decentralized controlled and has good scalability.
