Making use of the corba ' s excellent ability of the distributed object handling , fully considering the snmp ' s advantage of being widely supported , the thesis puts forward a kind of network management framework based on corba / snmp gateway . then , according to the framework , combining with itu - t " s recommendation of molding corba system by uml , the thesis models nms interfaces of requirement and analysis stage . the interface requirement is explained , and the static structures and dynamic behaviors are described with uml graphic syntax 本文分析了传统网管框架的不足,利用corba优秀的分布式对象处理能力,又充分考虑snmp支持广泛的优点,提出一种基于corba snmp网关的网管系统框架;然后,结合itu - t使用uml建模corba系统的建议,对网管系统接口进行了需求和分析阶段的建模,阐释了系统的接口需求,并使用uml图解语法对接口的静态结构和动态行为进行描述。
