摘　　要：网元管理系统在管理电信网络单元中起着非常重要的作用,而如何快速有效地构建适用于特定环境的管理系统是开发者面临的重要问题。文中根据TMN的思想,从高可用性和扩展性出发,提出了一个网元管理系统的设计和实现方法。该设计将整个系统分为3层结构:Java RMI服务层、业务逻辑层和数据操作层。对每一层的设计都遵循一定的软件开发模式,并对实现高可用性和扩展性过程中的一些关键难点提出了可行的解决方案。在实际使用中,该系统很好地适应了网络单元和功能的变动,达到了预期效果。Element management system plays a very important role in the management of network unit,and how to quickly and efficiently build the system is applicable to a specific environment is an important issue for developers. Propose a design and implementing method of net management system on the basis of TMN idea, with availability and scalability of the system as the starting point. The design divides the entire system into a three-layer structure：Java RMI service layer,business logic layer and data operating lay- er. The design of each layer follows certain software development mode to achieve the goal of high availability and scalability. Besides, some feasible schemes are proposed to solve the key technology of implementation. In actual use, the system is well adapted to changes in the network unit and function, and achieve the desired effect.
