Abstract

The present application relates to the technical field of SDN, and in particular, relates to a southbound interface-based network encryption method, system, medium and equipment. In order to solve the technical problem that the prior art does not have an effective solution for the controller to implement network service encryption. In this application, the SD-WAN controller reports the message according to the service quality status information, queries the encryption list, and obtains the encryption policy; the SD-WAN controller issues the encryption policy through the southbound interface; Encrypt and forward.

Description

technical field

[0001] The present application relates to the technical field of SDN, and in particular, relates to a southbound interface-based network encryption method, system, medium and equipment. Background technique

[0002] SDN technology migrates the control plane of the switching device to a centralized controller, and replaces the control plane in the switching device with a standardized southbound interface. The network control technology of the controller mainly includes link discovery through the southbound interface protocol, Topology management, policy formulation, table item distribution, etc. However, the following two issues are not considered:

[0003] (1) According to different network operating states and data security levels, the sdn network does not have a corresponding dynamic encryption mechanism.

[0004] (2) When the SDN network needs to be encrypted, the southbound interface of the controller does not have a relevant distribution mechanism. Cu...
