摘　　要：利用网格技术能够实现各种资源的全面共享与连通.通过结合Web服务技术和网格技术,形成了新一代的网格体系结构OGSA.开放网格基础设施(OGSI)是OGSA的软件实现模型和技术规范.GT3是第一个完全符合OGSA标准和OGSI规范的版本.网格服务通知机制是网格服务规范中定义的主要部分.OGSI通过一套WSDL接口,规范了网格服务的创建、管理、通信机制.本文深入分析了OGSI的通知机制及Globus工具集中的GT3对通知机制的实现,实现了一个具有通知功能的网格服务,并且总结了开发具有通知机制网格服务的流程.Resource share and connectivity can be realized by using grid technology. The new grid architecture--OGSA has formed by combining Web service technology and grid technology together. Open Grid Service Infrastructure（OGSI）provides a software implementation model and specification of OGSA. Globus Toolkit 3（GT3） is the first edition which is based on the core infrastructure compliant with OGSA and serves as a reference implementation of Open Grid Service Infrastructure（OGSI）. The Notification mecha- nism of grid computing is the main part of grid service standards. OGSI defines mechanisms for creating and exchanging information among grid services with a set of WSDL porttype. In this paper, based on analysis of notification framework in OGSI and in Globus Toolkit 3, an application of notification is given and its development flow is concluded.
