Network management method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides an SDN-based global network management implementation method and device, electronic equipment and a storage medium. The method is applied to an SDN controller,the SDN controller belongs to an SDN controller cluster, and each SDN controller in the SDN controller cluster is connected with a distributed database and is also connected with a plurality of switches to form a network domain; Any switch is at least connected with two SDN controllers; The network control method comprises the steps of obtaining first topology information between switches in a network domain; obtaining second topology information between switches in a network domain where other SDN controllers in the SDN controller cluster are located from the distributed database; determining global network topology information according to the first topology information and the second topology information; and controlling each switch in the network domain to carry out data forwarding based on the global network topology information. Therefore, according to the embodiment of the invention, the scale of the network topology is expanded, synchronous updating of global topology information is realized, and the requirement on the performance of the distributed database is low.

Description

technical field [0001] The present invention relates to the technical field of network management, in particular to a network management method, device, electronic equipment and storage medium. Background technique [0002] In recent years, the traditional network architecture has been insufficient to meet people's needs because of its management complexity and lack of flexibility. [0003] In order to meet people's needs for flexibility and simplicity of network management, the concept of SDN (Software Defined Network, Software Defined Network) has emerged. The core idea of ​​the SDN concept is software programmable. Based on the concept of SDN, OpenFlow (a network protocol) network without hierarchical network control mode is often used in network applications. [0004] Currently, in an existing OpenFlow network, usually only one SDN controller is used to perform centralized network management for all switches in the network. For example, suppose there are 1500 switches...
