| 摘 要： | 为了避免传统分布式存储系统的单点失效和路由瓶颈问题,将P2P资源定位模型引入其底层路由过程,以一种基于DHT(distributed Hash table)技术的结构化P2P路由模型Chord为基础,设计了一种新的分布式存储原型系统SPIS-DSS.SPIS-DSS采用Chord的一种实现JavaChord,把网络中的所有节点组织成环形拓扑,并通过幂次逼近的资源定位机制分发和回收文件,能运行在任何具有Java虚拟机的平台上,具有良好的可移植性.测试结果表明,这是一种有效的分布式存储系统,具有很好的可扩展性、健壮性和实用价值.

| Abstract: | To avoid the single-failure and routing bottleneck problems in traditional distributed storage systems,peer to peer(P2P) resource locating model is introduced and a new distributed storage prototype system SPIS-DSS(service oriented peer to peer networking integrated system-distributed storage system) over Chord,a type of structured P2P routing model based on distributed Hash table(DHT),is designed.Using an instance of Chord implementation JavaChord,SPIS-DSS arranges all nodes in the network to a ring topology,scatters and retrieves files by power-closing routing,and possesses good portability of running over any platforms with Java virtual machine.The test results indicate that it is a valuable distributed storage system with good extensibility,robustness and practicality. |
