Replica location strategy in education resource grid

Replica location is the key problem of replica mechanism.Based on the theory and model of content addressable network(CAN),the domain cluster CAN(DC-CAN) replica location strategy is presented for education resource grid.Two algorithms are in-troduced for allocation of cluster zones.The function of the algorithms is that the physical network structure of education resource grid can maintain topological isomorphic with the logical structure.It reduces the routing latency and at the same time keeps load balancing.The DC-CAN is proved efficiently in improving the routing performance by the analysis of experiments.
