Design of service-oriented flexible anchorage in migrating workflow system
面向服务的柔性迁移工作流停靠站设计

In migrating workflow system, the anchorage is the platform providing execution environment for the migrating instances. It should provide an integration framework for support services and application services, and adapt itself to the changes of its execution environments and the requirements of the workflow applications. Based on service-oriented concept, an extendable , customizable and reconfigurable architecture for the anchorage was presented. The whole architecture and the structure of the kernel was described. Some key techniques about this model such as the integration and organization of the service components, the deployment of the application service were discussed , and the reference implementation schemes based on the microkernel and component techniques were given.
