摘要 针对教育网格中数据资源共享的这个关键问题,主要在数据复制技术方面作了研究。在讨论了一种合理的副本目录管理模型后,提出了一种动态的副本创建策略,该策略提高了副本放置的效率,并能够适应用户请求的动态变化。 Data resource sharing is one of the key issues in the education grid. This paper focused on the data replication technology. After discussing a reasonable model for replica catalogue, this paper supposed a dynamic replica placement strategy, which could successfully improve efficiency of replica placement and adapt to change of users＇ request.
