In order to improve the efficiency of replica consistency management, one efficient consistency maintaining model is proposed. In this model, replica clustering coefficient is defined for representing social capacity, by which replica nodes are classified into multi-levels to form one replica-tree, and constitute a peer-to-peer network with first-class replica nodes of different VOs. The experimental results show that the proposed model can reduce conflict number and response time compared with some existing models.
