教育资源网格副本管理模型研究

Research on Education Resource Grid Replica Management Models

针对中小学的教育资源网格副本管理是当前网格研究的热点,总结了教育资源网格副本管理的相关概念,分析了副本管理的主要问题,并将其形式化表示。提出了基于OGSA的教育资源网格副本管理模型(OERM),其在提高用户访问速率的同时,方便了副本管理程序的开发。实验证实了OERM的优越性。

The education resource grid replica management models for primary and secondary schools is the hot issues of Grid. The related concepts for education resource grid replica management are aggregated. The major problems of replica management are analyzed and expressed formally. The OGSA based education resource grid replica management models（OERM） is presented, which speeds up the access rate for users and facilitates program development. The superiority of OERM is proved through the analysis of experiments.
