Embodiment Construction

[0065] 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.

[0066] The invention is used to solve the problems of time-consuming, labor-intensive, poor reliability and other problems of manual configuration of communication channels between the control layer and the data layer in the current large-scale SDN network. In view of the above problems, the present invention proposes a self-configuration technology for the communication channel between the control layer and the data layer of a single-controller SDN based on an authorized U disk to generate a white list. The technology of this invention is oriented to the SDN environment with only one controller. It collects information of legal devices based on the authorized U disk and forms a white list, which helps to realize mutual authentication between the control layer device and the data layer device; ...

Abstract

The invention discloses a communication channel self-configuration method facing a control layer and a data layer of an SDN (Software Defined Network). Through a self-configuration management step, a white list generated based on authorized USB flash disk in the SDN is used for finishing mutual authentication between a controller of the control layer and equipment of the data layer to establish a safety communication channel between the controller and the equipment.

Description

technical field [0001] The invention belongs to the technical field of computer network management, and 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 equipment), th...
