Combined with the practical application of the distributed file system,according to the balance of system and accessing efficiency of nodes,pointed out a strategy of replica management based on domain,establishing a cache for the node.When accessing a node,the replica stored in its domain was accessed firstly,and then the replica of neighborhood of current node was accessed.In this way,the access cost was reduced.Domain manager kept the balance of system by calculating,and then adding and deleting replica dynamically.These two methods can optimize the performance of overall system,to achieve fast and convenient access to the replica.
