Abstract:
This paper uses statistica lmethod to pred ict the popu larity of the files based on the access statistics and decides on the number o f the replicas according to the popu larity and the attributes of the file. Tak ing the attributes o f different servers into accoun,t the rep lica is placed on the co rresponding servers by themeans of dynam ic intervalmapping. The exper imenta l results show that th is replication strategy improves the performance and assures the load balance.
