摘要： 网络拓扑发现是图形化网络管理的基础。该文提出了一种跨虚拟局域网(VLAN)的物理网络拓扑发现算法,算法基于以太网技术,被管理设备支持SNMPv2。分别对实现了Bridge MIB、部分或没有实现Bridge MIB、服务器和路由器等节点提出了自动发现方法。算法应用于华北电力大学校园网的综合智能网络管理系统中,取得较好的成效。

Abstract: The network topology discovery is basic of network management based on graph.This paper proposes algorithm of physical network topology discovery based on multi-VLANs.The algorithm is based upon Ethernet technology,the equipments discovered must have implemented SNMPv2.The paper proposes discovery algorithm for realized entirely bridge MIB or partly bridge MIB or even nothing or servers and routers.The algorithm is applied to integration intelligent network management system of North China Electric Power University and procured better efficiency.
