【Abstract】 In order to ensure efficient and fast access such distributed data,the grid system adopted data replication.The paper introduced supermarket model in grid and propose the file replication strategy based on supermarket model in the interest of managing the file replication.Using both supermarket model and cascading replication to replicate files had the trust force and the pulling force in the procedure of file replication,and the overall system efficiency was enhanced.更多还原
