A Dynamic Data Replication Technology in Educational Resource Grid

Data resource sharing is a key issue in the education grid. In this paper, ice focused on the data replication technology. After discussing a reasonable model for replica catalog management, ire supposed a dynamic replica placement strategy, which can improve the efficiency of replica placement successfully and adapt to dynamic changes from users' requests.
