Discovery Algorithm for Network Topology Based on SNMP

Since computer network has become the basis of the information society, network topology has also become an important part of network management. The theory foundation of the network topology algorithm based on SNMP has been introduced in this paper, and the algorithms of network topology discovery based on SNMP have been mainly focused on. The algorithms in the network layer and link layer have been compared and expounded, and then the advantages and disadvantages of them have been summarized in the end.
