摘　　要：网络通信在当今高速发展的信息技术中占据着越来越重要的地位,作为其截体的世界上最大的通信网络——电信网的传输机制已从准同步数字序列(PDH)转向了同步数字序列(SDH)。SDH网络的各项强大的功能和优越的性能要通过先进的管理系统或管理网络才能体现出来。本文首先论述了系统的需求要点,基于统一建模语言给出了用例图描述的分析结果,并对相应的场景进行了分析;接着利用对象建模方法及其它一些主流的面向对象的技术对系统的建模进行了详细的分析与设计,包括从静态的类的结构分析和动态的类行为两方面进行了深入的研究,最后设计了系统的组件体系结构,本文的成果已在部分电信部门获得使用。Network Communication is playing more and more important role in modern information technology. As network communication's carrier, telecommunication network, the largest communication network, has finished transforming from PDH to SDH. Only by advanced management system or management network can the powerful functions and outstanding performance be manifested sufficiently. This paper firstly discusses the key points of the system's requirements, using the use case picture to express the results and then analyzing the relative scenarios. In succession, the Object-Oriented Methodology (OMT) method and other popular object-oriented methods are used to model the system in detail. The researches include both static structure analysis of classes and dynamic behavior of classes. Finally, a component system structure is designed for the system. The achievement of the system has been employed in several telecommunicate departments.
