Abstract: By using the way of P2P, a P2P storage system is built. The nodes involved in the system are grouped by the number of the subject of resources and the predicted network distance. The overlay network maintained by super nodes is formed, which implements effective management of nodes. Moreover, by using the multiplex naming mechanism of nodes, the efficiency of data storage in system is promoted. The performance of this storage system is testified on the basis of simulation experiment.

Key words: P2P storage system, topic overlay network, grouping, replication
