【摘要】 网格和OverlayNetwork已经引起研究领域和工业界的广泛关注,然而,工业、学术以及商业界的研究主要围绕网格的应用、服务和中间件,很少研究基础网络。论文提出了一种基于OverlayNetwork的自优化网格架构,并且展示了这一架构在数据管理领域的应用,如副本的生成、放置、访问优化、同步等等,这些都是利用部署在OverlayNetwork上独立的P2P组件协作实现的,并且所有组件是并发执行的,每一个组件根据自己的目标优化系统,通过很少交互且易处理的组件来完成优化,这个独立优化的方案与整体优化相比较,得到的结果相近,甚至更好,而且其复杂性更小。更多还原

【Abstract】 Recently,Grid and Overlay Network have attracted attention from research communities as well as industry. However,the overwhelming majority of industrial,commercial and academic activities are geared around applications,servers,and middleware.There have been some efforts in the management of the underlying networks,but far from enough.This paper proposes a framework for Self-Optimizing Grids Based on Overlay Network and shows how this new Framework can be deployed in the domain of data management.Here,the various management aspects like replica creation,placement,access optimization,synchronization,etc,are cooperatively solved with separate P2P component on Overlay Network.All components run concurrently.Each of them optimizes the system with respect to its goals.This separate optimization process performed by the interaction of small,manageable components gives similar or even better results,while being less complex than the holistic approach that tries to optimize the system in one step.更多还原
