网格与web服务结合应用研究

The application and study of integrating Grid and Web Service

将Web服务技术引入网格研究领域,有助于解决网格研究所面临的应用集成、资源共享、系统互操作和标准化等问题.本文在网格协议体系结构和开放网格服务架构(OpenGridServicesArchitecture,OGSA)的基础之上,将探讨网格系统与web服务的结合.首先讨论了网格功能模型,基于OGSA框架提出了Web服务的网格层次体系结构,并将Web服务工作流引入到网格任务描述中,给出一种Web服务与网格技术相融合的机制.

The introduction of Web Service into Grid field can help solve the problems in application,integration,resource sharing,and standard that the Grid research faces.Based on Grid Protocol Architecture and Open Grid Services Architecture,this article discusses Grid System integrating with Web Service.Within the OGSA(open grid service architecture) framework,a Web service-based Grid architecture is presented.An approach of integrating web services and Grid technology is proposed.Web Service workflow technology is used to model the task of the Grid application and its requirement on resource services.
