从全局全网出发对通信业务进行提供和保障,要求作为支撑体系中的网络管理系统之间能够动态协作。而分布式协作方式相对于集中式协作方式具有性能和可扩展性等方面的优势。分析了网络管理系统对分布式协作的需求,在一个基于Web services的动态协作网络管理体系结构的基础上,将网络管理系统间的协作转换为由网络管理系统提供的管理服务之间的协作,定义了异构网络管理系统之间的分布式协作机制,设计并实现了一个原型系统来验证该分布式协作机制。
The efficient fulfillment and assurance of communication services is one of the main objectives of network management. To provide and assure communication services from the overall network needs dynamical coordination between network management systems, which are significant parts of operation support systems. Since distributed coordination had better performance and extensibility than centralized coordination, the demands for distributed coordination of network management systems were analyzed. Based on a Web services-based dynamically cooperative network management architecture, by converting the coordination between network management systems to that between management services provided by those network management systems,a distributed eoordination meehanism between network management systems was proposed and a prototype was designed and implemented to validate the mechanism.
