Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] The method of the present invention belongs to the category of Software Defined Networking (SDN). Software-defined network is a new type of network innovation architecture at present. It transforms the traditional fixed routing configuration into a flexible software form, separates the control rights on network devices, and is managed by a centralized controller without the need for underlying network devices. , which shields the differences from the unde...

Abstract

The invention discloses an industrial communication flow transmission safety control method based on an SDN architecture. According to the method, a flow safety control module is designed in a management controller, deep analysis of industrial communication flow data is conducted, matching is performed with a preset industrial rule strategy, control processing operation in the industrial rule strategy is performed, and transmission control of the industrial communication flow is realized. The management controller comprises an industrial rule strategy database used for storing all industrial rule strategies set by users and an SDN switch maintenance flow table structure, the industrial communication flow is forwarded according to a flow table, and the flow table comprises a safety control identifier used for indicating whether the communication flow needs safety transmission control. According to the method, the legitimacy of the industrial communication data flow can be detected, access control for industrial communication which is not in accordance with the industrial rule strategy is realized, and the security and the reliability of an industrial control system based on the SDN architecture is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of industrial control system network security, and more specifically relates to an SDN architecture-based industrial communication flow transmission security control method. Background technique [0002] With the development of network technology, the existing network structure can no longer meet the needs of rapidly expanding network scale and continuously enriching application types. Countries all over the world have carried out research on future network architecture and made some progress. Software Defined Network (Software Defined Network, SDN) has received extensive attention from industry and academia. It is a new network innovation architecture and a way to realize network virtualization. Its core technology, OpenFlow, controls the plane of network devices It is separated from the data plane, thereby realizing flexible control of network traffic and making the network more intelligent as a pi...
