摘　　要：随着运营商的业务逐渐IP化,对IP网络的管理也越来越重视,IP网络的拓扑发现是IP网络管理的基础。为了完整、准确地进行IP网络的拓扑发现,采用了以SNMP作为节点和三层拓扑发现的技术、以SNMP和ICMP的结合作为二层拓扑发现的技术,经过在运营商现网网络的实验验证,能100%发现所有节点及链路,证明了该方法能完整、准确地发现IP网络的拓扑。With the operator′s business gradually IP,the IP network management should be paid more and more attention,IP network topology discovery is the basis of IP network management.For carrying on the IP network topology discovery completely and accurately,using the SNMP topology discovery as nodes and three techniques to a combination of SNMP and ICMP as a technical layer topology discovery,based on the experimental verification of the operator′s current network,all nodes and links can be found 100%,this method can completely and accurately discover IP network topology.
