Abstract


In recent years, the rapid development of social networking sites , the number of registered users increased dramatically, user data shared through social networking sites also increases the amount of computer storage system scalability presents new challenges. Based on Peer-to-Peer (P2P) architecture applications have become an important form of a new generation of Internet applications , P2P application architecture brings better scalability , fault tolerance , and higher performance. Storage system based on P2P technology has become an important research focus , is considered the most promising applications of P2P . This paper discusses a P2P-based architecture highly scalable key storage system that uses virtual nodes consistent hashing algorithms and techniques to achieve high system scalability while maintaining load balancing, data query in order to reduce delays, each storage nodes are preserved system global routing information , read and write operations can hop to reach the appropriate storage node. System is based on a hierarchical node Heartbeat routing information maintenance mode allows nodes to join quit message to quickly and accurately communicated to each node. The data storage system to each stored separately to multiple servers in order to improve data availability , response storage node and network failures caused data loss.
