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 is illustrated in conjunction with specific implementation figures, and the method of the present invention is described completely and clearly. The described examples are only part of the examples of the present invention, rather than specific implementation examples of all methods. Based on the embodiments of the present invention, all other embodiments that may be obtained by persons skilled in the art without making creative labor 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 a current innovative architecture network solution, with OpenFlow technology as the core technology, through the centralized strategy formulation of the controller and the execution of the switch strategy, the separation of the control layer and the forwarding layer is realized. , so as to establish a dynamic policy enforcement mechanism for th...

Abstract

The invention discloses a wireless mesh safety hierarchical transmission method based on an SDN. The method includes: a strategy generation stage, a strategy distribution / maintenance stage, a strategy update / loading stage and a strategy execution stage. According to the method, transmission requirements of data flows with different safety demands can be flexibly met based on an SDN architecture, problems of poor flexibility of the network function and high update cost are solved, the method is in accordance with safety hierarchical transmission of the conventional network protocol, safety hierarchical transmission of wireless data messages is guaranteed, and better protection is provided for the data messages with high safety level.

Description

technical field [0001] The present invention relates to the technical field of wireless Mesh network security, and more specifically relates to an SDN-based wireless mesh security hierarchical transmission method. 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 the "last mile" issue of the industrial control system, industrial wireless Mesh is a very widely used organizational form. At present, the domestic Relevant technical standards have been formed at home and abroad for promotion and implementation, and good results have been achieved. The hierarchical structure of the traditional web is the key to the great success of the Internet. However, with the continuous expansion of the network scale, too many complex protocols are built into the closed network equipment, which increases the difficulty for operators to customize and optimize the ne...
