Network topology sensing method and device

Abstract

The embodiment of the invention provides a network topology sensing method and device. The method comprises the steps of acquiring subnetwork information of a plurality of subnetworks corresponding toa to-be-sensed network; acquiring device information in the corresponding subnetwork through adoption of a discovery technology based on a simple network management protocol, according to the subnetwork information of each subnetwork; and acquiring a topology structure of each subnetwork through adoption of a link layer protocol discovery technology and a depth scanning discovery technology basedon the device information in each subnetwork. The device is used for performing the method. According to the embodiment of the invention, the device information is acquired through adoption of the discovery technology based on the simple network management protocol and connection relationships between devices and ports are acquired through adoption of the link layer protocol discovery technologyand the depth scanning discovery technology, so the topology structure of each subnetwork is sensed relatively rapidly and comprehensively.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of computer networks, and in particular to a network topology sensing method and device. Background technique [0002] With the advent of the information age, the relationship between people and the Internet is getting closer, and the network carries more and more information, so the network information security problems are also increasing. The dependence on the computer network makes the reliability of the computer network itself very important, and there are higher requirements for network management. [0003] A network consists of connected network entities, which mainly include routers, servers, switches, and hosts. Through the network protocols and services running on these entities, users can obtain various services and complete different tasks. A network protocol is an agreement that computers must abide by when communicating in a network, that is, a communication protocol. I...
