摘要
一方面信息量的爆炸式增长对传统的存储模型提出了严峻挑战,另一方面宽带广泛普及、计算机性能大幅度提升,在此背景下,以Peer-to-Peer的方式对存储资源进行管理成为可能。提出了系统的体系结构和模块组织,重点探讨存储资源的发布与发现以及数据的存取与维护,通过覆盖网的路由和定位机制均衡存储管理负载,通过数据分片与副本机制增加系统可靠性,并对系统的设计与实现要点进行分析。结果表明对等式存储系统是可行的。
On the one hand the explosive increasing of information quantity poses a serious challenge for traditional storage system, on the other hand broadband has been popularized and the computer performance has been greatly promoted, on which background it is applicable to build a storage system based on peer-to-peer model. Firstly, the system architecture and models are presented, then focusing on sharing and discovering of storage resources as well as data accessing and maintaining, the load balance of storage management is achieved hy the peer-to-peer muting and location mechanism and the reliability and availability are achieved by fragment and replica algorithm. By analyzing the key points of design and implementation, argue that the storage system based on P2P is viable.
