摘　　要：基于SNMP的物理拓扑发现为通用网管平台提供了物理拓扑发现功能。分析比较基于网桥转发表和基于网桥生成树的拓扑发现算法,结合两种算法的优点,提出一种新的以太网拓扑发现算法,该算法简单高效而且适用范围广;最后给出算法的实现与测试结果。Network topology discovery is the basic function of many network management systems, The physical topology discovery algorithm was analyzed and compared relying on standard SNMP MIB FDB and the algorithm relying on STP information in the first place, Then a new algorithm for discovering Ethemet topology was presented, which had the advantages of the two algorithms. Implementation of this algorithm could determine the physical topology simply and efficiently, and could be applied to all kinds of Ethemet networks.
