Abstract

Data Grid is an infrastructure that manages huge amount of data files, and provides intensive computational resources across geographically distributed collaboration.To increase resource availability and to ease resource sharing in such environment, there is a need for replication services.Data replication is one of the methods used to improve the performance of data access in distributed systems.However, it is bounded by two factors: size of available storage and bandwidth of sites within the Data Grid. Hence, there is a need for replica replacement strategy.In this paper, we propose an exponential based replica replacement strategy (ERRS).OptorSim is used to evaluate the performance of this dynamic replication strategy.The simulation results show that ERRS successfully increases data grid performance.
