A Frequency Sensitive Dynamic Replication Management Mechanism
Xu Zhou · 2005
This paper presents a novel distributed adaptive Frequency Sensitive Replica Management mechanism (FS- RM). In FSRM, in order to improve system performance and reduce network traffic, every replica of a certain file checks its state periodically to find out the access mode during the period of time,then decides whether move,delete it- self or copy a new replica to another node. The interval of periodicity of each replica is also variable,it can be changed according to the access frequency of a replica,so that we can improve performance greatly with less system overhead, and realize a multi-leveled sensitive dynamic replica management. In the end,the paper evaluates the efficiency of FS- RM by experimental result and shows the performance enhancement.
