| Abstract:With the increasingly complex operation and maintenance scenarios and the urgent need for unified management of network devices in the automation operation and maintenance process，the research on automatic topology discovery technology for network devices become very important in large enterprises. According to the actual operation and maintenance requirements，simple network management protocol （SNMP） and Internet Control Message Protocol （ICMP） are selected for topology at the link layer，and SNMP protocol topology discovery is selected at the network layer，in order to topology discovery accurately，quickly，and completely. The topology discovery algorithm is designed and implemented，and the validity of the method is verified in the experiment. It can be used for topology discovery of large-scale networks in automatic operation and maintenance system. |
