摘要
计算网格允许对地理域上分散的资源进行大范围的、深入的、一致的共享。它们的固有属性将发现处于不同行政区域的资源和预测资源的性能并监控其行为的事务进行合并。监控和发现服务MDS(Monitoring and Discovery Service)是Globus工具集提供的一项主要服务,它可以用于为已存在的基于代理的资源发布和发现系统提供网格信息服务。给出一个代理系统,它使用MDS中的网格信息协议GRIP(Grid Information Protocol)和网格注册协议GRRP(Grid Registration Protocol)去发现虚拟组织并监控相关资源,使得此系统具有资源代理、监控及性能预测的作用。
Computational grids allow large-scale,in-depth and consistent sharing of geographically d!sPersed resources. Their inherent nature incorporates transactions including discovering resources located in different administrative domainS, predicting the performance of those resources and monitoring their behaviour. The Monitoring and Discovery Service（ MDS）, one of the pillars provided by the Globus toolkit, can be used to offer Grid information services to an existing agent-based resource advertisement and discovery system. This paper presents an agent system which implements the Grid Information Protocol（GRIP） and the Grid Registration Protocol（GRRP） of the MDS to discover virtual organisations and monitor their respective resources. The resulting system has the effect of resource brokering, monitoring and performance prediction.
