Method for discovering network topology and related equipment

Abstract

The invention discloses a network topology discovery method and related equipment thereof. The method comprises the following steps: acquiring a spanning tree protocol (STP) result of a switch; processing the STP result of the switch to obtain the topological connection relationships of uplink ports of the switch; judging whether a switch uplink port with an undetermined topological connection relationship exists, and, if yes, obtaining the topological connection relationship of the switch uplink port with the undetermined topological connection relationship according to the MAC address forward table of the switch uplink port with the undetermined topological connection relationship. The invention further discloses a network information processing device with a network topology discovery function. In the method, the link layer topological connection relationship discovered by the STP result and the link layer topological connection relationship discovered by the MAC address forward table are closely related, so that the method can accurately discover and obtain various types of topological connection relationships of the switch uplink ports.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a network topology discovery method and related equipment. Background technique [0002] With the development of network technology, the scale and complexity of the network continue to expand, which prompts users to have higher and higher requirements for network management. [0003] As a prerequisite for completing many network management tasks, network topology discovery is mainly divided into network node discovery, network layer topology discovery and link layer topology discovery. Among them, the purpose of network node discovery is to discover the network nodes and network node information that constitute the network, such as discovering switches, routers, hosts, etc., and the information of these nodes; the purpose of network layer topology discovery is to determine the topology between subnets in the network Connection relationship; the purpose of link layer topology dis...

Problems solved by technology

[0017] The existing method uses Ping in the management domain to discover the active IP addresses in the management domain, that is, discover the active network nodes in the management domain, but in the actual network, the number of network nodes that are host-type nodes in the management domain is far more Due to the number of network nodes (such as routers and switches), most host nodes are forbidden to respond to Ping. Therefore, using Ping to discover active network nodes in the management domain will lead to inefficient and time-consuming network node discovery.
