Network topology discovery method and device and electronic equipment

Abstract

The invention discloses a network topology discovery method and device and electronic equipment, and aims to at least solve the problems that an existing network topology discovery method is low in accuracy, and configuration complexity and operation load of network equipment are increased. The method comprises: acquiring public network port information of a plurality of network devices in a target network and LACP information of a target network device that opens a link aggregation control protocol LACP, the LACP information comprising home terminal system parameters and opposite terminal system parameters of a port aggregation group, port numbers of member ports in the port aggregation group and opposite terminal port information; performing network topology discovery based on the public network port information of the plurality of network devices to obtain first network topology information; performing network topology discovery based on the LACP information of the target network device in the target network to obtain second network topology information; and determining the network topology of the target network based on the first network topology information and the second network topology information.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a network topology discovery method, apparatus, and electronic device. Background technique [0002] Network topology refers to the physical layout of various devices interconnected by transmission media, which reflects the connection relationship between various network devices in the network. Network topology discovery is to obtain and maintain the existence information of various network devices and the connection relationship information between them, so that network managers can locate network faults on this basis. [0003] At present, the common network topology discovery method is to use the Link Layer Discovery Protocol (LLDP) to obtain the name and port information of the peer device, and to complete the recording and association of the topology information based on this, and finally obtain the network topology; The routing information of each ne...
