Aiming at the problem that it hard to keeping replica data consistency in unstructured P2P network, a novel data replica consistency update strategy is proposed. The replica consistency scheme consisted of two parts on the basis of the current popular super-peer structure of p2p network. First part, in super peer layer, the replica consistency is maintained by using Inter-Domain Version Vector. Second part, in the domain of any super peer, the consistency is maintained by using Inner-Domain Version Vector. This double-layer consistency maintenance strategy can not only keep the replicas be consistent, but also reduce the bandwidth caused by the update operation as well. The simulation results indicate that DVV shows better performance than the compared strategies in the current unstructured p2p network.
