AB - With the rapid development of computer network and the fever of office automation, data storage gains more and more attentions. In recent years, P2P system-one of data storage networks, has been studied widely because of its high performances (e.g. in terms of distributed and extensibility). One of data storage challenges in it is how to improve data survivability under churn, which is caused by nodes’ joining or leaving in the network. Increasing replicas is a comparatively good way to enhance the system fault tolerance, especially under high churn. According to existing references of the replication strategy which always focus on specific P2P systems, we propose a balanced replication method based on the zones partition-BRBZs which mainly consists of the copy distribution mechanism, the query mechanism and the consistency maintenance mechanism. It is a general way that BRBZs can be applied in different P2P networks. Meanwhile, we evaluate the performance of the BRBZs strategy by applying it in DHT systems with different routing protocols to compare with other replication strategies. Performance indexes are innovatively divided into dynamic and static indexes, making the evaluation of algorithm performance more comprehensive and accurate. Simulation results declare that the BRBZs has not only better data availability, higher query efficiency and lower searching fail-rate, but good scalability to be applied in systems with different sizes. Besides, the system applying BRBZs is convenient for management and maintenance as its user access interface bases on different protocols without centralized servers.
