摘要 数据网格资源的增加、地域分布的扩大,引起了网络性能的下降及传输的延迟,这些问题使得动态复制算法的可扩展性变得尤为重要。而目前数据网格中的动态复制算法均不具备良好的可扩展性,为此该文提出了基于分层管理的拓扑HMLT上的动态复制选址策略,并将其应用于远程教育的资源管理中。 Data replication is considered a major technique for reducing network latency and bandwidth consumption in data grid. Whereas hardly no dynamic replication strategies has the excellent scalability which is emphasized for large-scale high-latency network, this paper gives highly scalable dynamic replication strategy based on the HMLT. Then, it shows how to realize the strategy in resource management of Chinese remote education.
