摘　　要：研究并提出了一种基于SNMP的拓扑自动发现的改进算法。与一般拓扑发现算法相比,改进算法可发现指定深度网络内所有路由设备及指定子网内所有活动主机,解决了包含三层交换机的网络中拓扑发现不完整的问题,并对改进算法中网络设备相关MIB对象解析以及指定子网中活动主机发现等关键技术进行了分析。An improved SNMP-Based network topology auto-discovery algorithm has been examined and put forward. Compared to the traditional topology discovery algorithm ,the improved algorithm can find all muting devices in the depth-specified network and all active hosts in the specified subnet, which has resolved the problem of incomplete topology discovery in networks containing layer 3 switches. Moreover, some key techniques in the improved algorithm, such as how to obtain the relative MIB objects in network devices and how to find all active hosts in the specified suhnet, has also been analyzed.
