For the aim of prefetching and buffering data,a strategy called strategy of dynamic replication creation based on clustering(DRCC) is proposed.It abstracts the characteristic of access data according to the access history of users.And then,judges the correlation among the files.And then,through clustering operation creates the correlative file class sets relating to the access requirements of users.It also produces the data files replica on the basis of those sets.The simulation results show that DRCC has the ability of identifying the access requirements of client nodes effectively.On the other hand,the replication of files based on it reduces the access time of client nodes and improves the efficiency of system.In the mean time,DRCC has greater applied adaptability.
