Abstract

In the semistructured P2P storage system architecture, replica is the effective assurance to improve data availability. This paper measures the number of replicas according to the Node Online Rate and the frequency value of the resources accessed. It better reflects the node behavior characteristics of highly dynamic P2P networks, and designs a recovery strategy for redundant data. The experimental results show that the design method uses a certain amount of bandwidth for maintenance, but the availability of the resources in the network is significantly enhanced.
