摘要： 在分析了网络三层拓扑和二层拓扑发现相关协议的基础上，提出了一种仅依赖SNMP协议，实现跨多子网的混合以太网物理拓扑发现算法，给出了算法的实现步骤。该算法不仅可以发现网络上的路由器、交换机等可网管设备，而且具有发现主机、集线器和非网管交换机等哑设备的特点。实验显示，算法运行正确，可以发现各种网络设备，准确识别链路连接类型，是解决该问题的一种有效方法。

Abstract: According to the analysis of the correlative protocol of discovery network 2-layer and 3-layer topology, this paper submits an algorithm of across multi-subnet physical topology discovery that depends on SNMP protocol only. This algorithm has a character that can discover not only the managed devices (e.g. routers and switches), but also the dumb devices (e.g. hosts, hubs and non-managed switches). The experiment demonstrates this algorithm is correct which can discover all sorts of network devices and correctly identifies types of link, and an effective means of solving this problem.
