摘要
资源发现是实现网格系统的基础功能之一。资源发现的各种方案通常都要维护、查询一个资源状态数据库。为了维护资源状态数据库的一致性,资源状态数据的分发是其中一项关键操作。本文通过对几种资源状态数据分发方法的考察,提出了一个用于控制网格系统中数据分发范围的新概念：网格势能。
One of the fundamental operations needed to support Grid computing is resource discovery.Generally,resource discovery schemes maintain and query a resource status database.Dissemination of the resource status information is one of the key operations required to keep the resource status databases consistent.This paper examines several approaches for resource status dissemination.A new concept called the Grid potential is introduced in this paper.This concept is used to control the extent of data dissemination in Grid systems.
