Analysis and Design of SDH Network Management System Based on UML
基于UML的SDH网管系统的分析与设计

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.
