Abstract
This paper presents a novel decentralized dynamic replication management mechanism based on accessing frequency detecting (FDRM).In FDRM, in order to provide better system performance and reduce network traffic, system node scans the local replica of a certain file to detect its access pattern, and makes decision independently to add, delete or migrate a replica for that file. In addition, the scanning interval of a replica is variable according to the accessing frequency to that replica, which makes FDRM more sensitive to the change of system behavior, and we can get better performance with less system overhead. In the end, the paper evaluates the efficiency of FSRM by experimental result and shows the performance enhancement.
