Embodiment Construction

[0080] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0081] The present invention proposes a self-configuration technology for a communication channel between a control layer and a data layer of a single-controller SDN based on a symmetric key. The invention is used to solve the problems of time-consuming, labor-intensive, poor reliability and other problems of manual configuration of communication channels of the control layer and the data layer in the current large-scale SDN network. The technology of the present invention faces the SDN environment with only one controller, and realizes the mutual authentication between the control layer device and the data layer device based on the symmetric key technology; after the authentication is passed, the communication channel self-configuration process between the control layer and the data layer can ...

Abstract

The invention discloses a self-configuration method for a communication channel between a data layer and a control layer of an SDN network. In an SDN environment, devices such as a controller and a switch automatically perform mutual authentication based on symmetric key technology. After the authentication is completed, pass The self-configuration management step establishes a secure communication channel between the controller and the device.

Description

technical field [0001] The invention belongs to the technical field of computer network management, and in particular relates to a method for automatic configuration of a communication channel between a control layer and a data layer of an SDN (Software Defined Network, referred to as SDN) network. Background technique [0002] With the rapid development of emerging services such as cloud computing and big data, the transformation of the network is urgent. Under this trend, the development space of SDN technology will become more and more extensive. As more and more enterprises and operators choose to add SDN to their networks, the demand for large-scale networks based on SDN will continue to increase. However, the cost and manpower invested in the early stage of SDN network construction (before the completion of SDN functions) will obviously hinder the promotion of SDN. Excluding the necessary costs for equipment upgrades (from traditional network equipment to SDN-enabled ...
