Network topology generation method based on equipment and link discovery, storage medium and terminal

Abstract

The invention provides a network topology generation method based on equipment and link discovery, a storage medium and a terminal, and the method comprises the steps: recognizing routers in a network, obtaining the IP addresses of all routers, and forming an IP data set; traversing all the IP addresses, carrying out on-off test on each IP address, and adding the IP address of which the test result is that the information is reachable to the router table; constructing a link relation table between the routers and a link relation table between the routers and the subnets; establishing a switch information table, and obtaining a port address of a switch; according to the established link relationship between the router and the subnet, carrying out IP matching on the switches in the information table of the switches through the network segment of the subnet mask, and forming a relationship table between the subnet and the switches connected with the router; obtaining an available port of the switch, and writing the number of the available port into a relation table between the subnet and the switch connected with the router. The invention has the beneficial effect of facilitating topology management, and is suitable for the field of computer networks.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a network topology generation method based on device and link discovery, a storage medium and a terminal. Background technique [0002] Network topology can well reflect the structural relationship of each device in the network, assist management and performance analysis, and have a significant impact on the performance of the entire network. [0003] With the development of network technology, more and more network devices appear in the local area network. The network devices located in the same local area network are discovered through devices, and the heterogeneity between devices and protocols has brought great impact on network topology discovery. Difficulties. Contents of the invention [0004] Aiming at the deficiencies in the related technologies, the technical problem to be solved by the present invention is to provide a network topology generation method ba...
