GridDaEn数据网格中的元数据预取与缓存策略
The Prefetching and Caching Strategy of Metadata in GridDaEn Data Grid
摘要
Abstract
For Data Grid system is deployed in wide-area network environment, network-delay becomes one of the major limiting factors of QoS. After further discussing of prefetching method, we employ space-exchange-time method and then put forward a kind of metadata-based prefetching and caching strategy. In addition, considering the specific characteristic of the metadata in GridDaEn system, we propose a novel kind of profetching method called DHMP.关键词
