摘要：An effective replica management method can save bandwidth, reduce latency, balance load, and improve system reliability. A comprehensive scheme is introduced to manage replica for the grid environment. The schemes of replica creation and placement based on the frequency of visits and storage space, replica replacement based on the replica value, and replica selection based on comprehensive performance are proposed. Our scheme can achieve optimization of data distribution and replication, improve the efficiency of data visits in the grid environment.
