Abstract

The invention provides a network topology acquisition method and device based on a software-defined network (SDN), which is applicable to an SDN controller. The method comprises the following steps: acquiring linear topologies and / or ring topologies among SDN switches in the SDN; and carrying out superposition of the linear topologies and / or the ring topologies to obtain an overall topology of the SDN. The method and device provided by the invention has the advantages that the problem of low efficiency in direct acquisition of a topological structure of a complicated network in the prior art is solved, the discovery speed for a complicated network topology is improved, an overall view of a complicated network structure can be acquired in a more real-time manner, and the network topology can be more flexibly acquired.

Description

technical field [0001] The present invention relates to the field of information communication technology, in particular to a method and device for acquiring network topology based on software-defined network (SDN). Background technique [0002] At present, the application of the three-layer network structure is very extensive and the technology is mature. However, with the development of technology, its bottlenecks are constantly emerging, which leads network engineers to gradually choose to abandon the network with this structure in the network design. As more and more enterprises seek to maximize utility and maximize the utilization of data centers, the mainstream three-tier network topology is increasingly unable to meet the demand, and the surge in traffic makes the traditional three-tier network structure have very obvious performance attenuation. . The leaf-spine network topology can effectively solve this problem. By adding a layer of horizontal network structure pa...
