摘要 教育网格是教育信息化的主要发展方向,对教育网格拓扑结构以及副本创建策略进行了研究。在基于因特网的教育网格环境中,基于GLOBUS平台对整个网格系统进行了划分,将其划分为若干个存储子域,在此基础上提出了域内和域间副本创建策略,并对该策略进行了分析与探讨。分析表明,该策略有效地改善了用户访问时间和因特网的带宽消耗。 Educational grid is the main direction of educational information, the educational grid top structure and the replica strategies are researched. The educational grid is in the Internet environment, which is based on GLOBUS Platform. The educational grid is divided into several storage subregions. A new replication strategies is proposed, including intra-subregion and inter-subregion strategies. The analysis indicate that the new strategies improve the user＇ access time and bandwidth consumption of the Internet.
