物理网络拓扑指的是一个通讯网内部实体的物理实际链接,准确自动获取物理网络拓扑图是完成许多重要网络管理任务的前提。以物理网络拓扑发现构件设计与实现过程为例,以UML为建摸语言,介绍了一种利用设计模式设计构件具体功能的方法。 Physical network topology refers to the actual physical link of an internal communication network. Accurate and automatic access to the physical network topology is the prerequisite for accomplishing many important network management tasks. Taking physical network topology discovery component design and implementation process as an example, taking UML as modeling language, this paper introduces a method to design the concrete function of component by using design pattern.
