面向服务的柔性迁移工作流停靠站设计

在迁移工作流系统中，停靠站服务器是迁移实例的运行支撑平台，必须能够支持多种支撑服务和应用服务的集成，适应运行环境和应用需求的动态变化。基于面向服务的概念，提出了一个可扩展、可定制和可重配置的停靠站服务器结构模型，描述了模型的体系结构和内核结构，讨论了服务组件的集成框架和组织模式，以及应用服务的部署模式等，并结合微内核和组件技术给出了参考实现方案。

Design of service-oriented flexible anchorage in migrating workflow system

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.
