| 摘 要： | 开放网格服务基础结构OGSI（Open Grid ServicesInfrastrstructure）把Web服务工作流引入到网格任务描述中，给出了几种Web服务与网格技术相融合机制，但并没有界定如何进行网格服务组合.而BPEL4WS（Business Process Execution Language for Web Services）是描述Web服务业务工作流的工业标准.通过对BPEL4WS和OGSI在生命周期管理、Web服务实例化和状态交互管理等方面异同的深度分析，提出了一种兼容OGIS并使用BPEL4WS来合成网格服务的高层体系结构.介绍了一个电力网电能损耗理论计算的实际应用原型系统，表明该文提出的体系结构可应用于网格服务的建模和构造.

| Abstract: | The Open Grid Services Infrastrstructure(OGSI)incorporates Web services technologies to facilitate resource sharing,but it does not address overarching concerns of grid service composition.BPEIAWS(Business Process Execu- tion Language for Web Services)is an industrial process modeling language standard for composing Web services.This paper provides an analysis of BPEL4WS and OGSI in terms of their similarities and differences focusing on life cycle management,Web service instantiation and stateful interaction.Based on the analysis a high-level architecture that pro- vides saparate ties for composing and resolving Grid services is presented.The proposed architecture has been applied to a theoretical energy loss calculation system for power grid.which consequently shows in the OGSI framework orches- trating Grid services with BPEL4WS is feasible and effective. |
