Abstract :
Replication strategies directly affect the performance of grid resources in data grid. As the replication strategies are of great importance to data grid, this article built up a simulative environment with OptorSim simulators, and analyzed different replication strategies according to different accessing models. It is verified by the simulation results that the replication strategies adopted in this article can greatly cut down the system cost of single operation and make the best of each computing unit.
