改进的网格资源信息更新策略

网格是构筑在互联网上的一种新型技术,正成为新一代的网络基础设施。网格的目的是把网络的资源有效的整合,实现资源的跨组织、跨地域的动态共享,因此网格资源的有效管理成为网格研究中的关键技术之一。数据变化更新策略是在资源状态发生变化时通知资源信息中心更新数据。在数据变化更新策略的基础上,提出了一种改进的资源更新策略:如果资源状态信息的变化超过了一定的幅度,资源才发出信息更新通知。

An Improved Policy of Resource State Update

Grid is a new technology that build on World Wide Web,it is being a new generation of network infrastructure.The goal of the Grid is to intergrate the resources in the network effectively,to realize the dynamic resources sharing across organization and area.So it is an important technique for the Grid to manage the resources in the Grid.The policy of update with data changing meant that the resource will notify the information center when the state value is changed.On the basis of the policy,we advance a new policy called improved policy of resource state update.
