File replication and file consistency maintenance are widely used techniques in peer-to-peer file sharing systems for high system performance and optimum utility of P2P networks. Despite significant interdependencies between them, these two issues are typically addressed separately. Existing file replication methods rigidly specify replica nodes, leading to underutilization of replicas, clumsy performance with unnecessary replicas and hence require extra consistency maintenance overhead. Most consistency maintenance methods updates, propagates messages operating without considering the issues involved in file replication dynamism, leading to inefficient file update and hence high possibility of outdated file response.
