摘要 针对Web服务工作流随着服务的动态产生和消失,导致工作流的可用性受影响的现象,提出了一种基于服务虚拟平台的服务工作流可用模型——High-Workflow,论述了可用模型的结构体系、组织协议。该模型有效地屏蔽了组成工作流的Web服务物理上的差异,通过Web服务的复制与备份提高了工作流的可用性,在理论上分析了模型的可用度,通过实例验证了该方法的有效性。 Aimed to the problem that the availability of Web service workflow is influenced for the dynamic bringer and disappearance of service in the Internet, this paper proposes a method of available service workflow based on service virtual system, and analyzes the method＇s structure architecture and organized protocols. It can effectively shield the physical difference of Web service and improve the availability of workflow by copying and backuping Web service in Internet. In the end, the validity is tested by the theory analyses and a real application.
