Abstract

The invention discloses a secure data transmission and control system based on an SDN (Software Defined Network) multi-domain network, which comprises a user registration and login unit, a data collection unit, a data recognition unit, a data processing unit, a data distribution unit and a data storage unit. According to the method, the to-be-transmitted data uploaded by the user and the recognition data are integrated to obtain the transmission data, so that the data is marked, and later tracing processing on the data is facilitated; by setting transmission priorities, performing different types of queue calibration and performing classified transmission on transmission data according to user requirements, the transmission data can be transmitted according to a certain priority logic, sothat the transmission efficiency can be effectively improved, the data security can be improved. Meanwhile, bad data can be recognized and processed, the network environment can be effectively purified, and the user experience is improved. And the use experience of network users is improved.

Description

technical field [0001] The invention relates to a data transmission and control system, in particular to an SDN-based multi-domain network security data transmission and control system. Background technique [0002] SDN is a recently emerging network technology, which enables network structure innovation, and at the same time allows network operators to control, customize and optimize their own infrastructure more, thus reducing overall capital and operating costs. [0003] SDN is an emerging network architecture that separates network control and forwarding, and can be programmed directly. Migrating the control to the computing device, the upper-layer applications and services abstract the underlying facilities, and regard the network as a logical or virtual entity. However, in the application process of SDN, the data information in the network varies in size, so The required levels of security protection are also inconsistent. If they are mixed together, it will lead to w...
