%X Fully considered the characteristics of P2P network,which are heterogeneity and high dynamic,and applied the advantages of existing data replication techniques,a self-organizing document storage strategy and a self-adaptive replication strategy are designed.Specially,the self-adaptive replication strategy takes account of the node's general performance and combines the most query strategy and the LRQ(Least Recent Query) strategy.Furthermore,the combination of these two strategies can effectively improve the reliability of the storage objects and the availability of the sharing information.In addition,the balance of the system load can be effectively and dynamically adjusted,and the scalability and stability of the system are further guaranteed.The design will be applied to a DHT topology based file storage and sharing system with good scalability and compatibility.
