Problems solved by technology

[0005] In order to adapt to future intelligent manufacturing factories, industrial wireless mesh networks need to meet the characteristics of flexible change, dynamic configuration, and interconnection. The current implementation of AP nodes is not suitable for the development of diversified technologies in the future. Security is also the most important attribute of intelligent manufacturing factories. One, it is necessary to study the secure transmission mechanism under the new network architecture

Embodiment Construction

[0033] The present invention will be described in combination with specific implementation diagrams, and the method of the present invention will be described completely and clearly. The described examples are only a part of the examples of the present invention, not all specific implementation examples of the method. Based on the embodiments of the present invention, all other embodiments that may be obtained by those skilled in the art without making creative work results fall within the protection scope of the present invention.

[0034] The method of the present invention belongs to the category of Software Defined Network (SDN). SDN is the current innovative architecture network solution. It takes OpenFlow technology as the core technology and realizes the separation of control level and forwarding level through centralized strategy formulation of the controller and execution of switch strategy , So as to establish a dynamic policy execution mechanism for the entire network. ...

Abstract

The invention discloses an SDN-based wireless mesh security hierarchical transmission method, which includes: a policy generation phase, a policy distribution / maintenance phase, a policy update / loading phase and a policy execution phase. Based on the SDN architecture, the method of the present invention can flexibly meet the transmission requirements of data streams with different security requirements, solve the problems of poor flexibility of network functions and high update costs, and conform to the security hierarchical transmission of existing network protocols, ensuring the security of wireless data messages Hierarchical transmission enables better protection of high-security data packets.

Description

Technical field [0001] The invention relates to the technical field of wireless Mesh network security, and more specifically to a wireless mesh security hierarchical transmission method based on SDN. Background technique [0002] With the background of the national "dual network" integration, the combination of the Internet and the industrial control network is inevitable. For industrial control systems in the "last mile" issue, industrial wireless Mesh is a very widely used organizational form. Foreign capital has formed relevant technical standards for promotion and implementation, and achieved good results. The hierarchical structure of the traditional network is the key to the great success of the Internet. However, with the continuous expansion of network scale, too many complex protocols are built into closed network equipment, which increases the difficulty for operators to customize and optimize the network. Researchers cannot deploy new protocols on a large scale in a r...
