Embodiment Construction

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0018] Such as figure 1 It is a frame diagram of the multi-mode arbitration system based on time iteration and negative feedback mechanism of the present invention, the multi-mode arbitration system includes: a heterogeneous pool unit, a multi-mode arbitrator and a negative feedback unit; the heterogeneous pool unit contains more than 3 heterogeneous structure SDN controller; in each SDN control layer, use the heterogeneous SDN controller to process the input request at the same time, and submit the output result set of each SDN controller per unit time to the multi-mode arbiter; the multi-mode arbiter The controller conducts a consistent ruling on the information distribution in the ...

Abstract

The invention discloses a multi-mode ruling system based on time iteration and a negative feedback mechanism. The multi-mode ruling system comprises a heterogeneous pool unit, a multi-mode ruling device and a negative feedback unit, wherein the heterogeneous pool unit comprises three or more heterogeneous SDN controllers; in each SDN control layer, the heterogeneous SDN controllers are used for processing input requests at the same time, and submit an output result set of each SDN controller in unit time to the multi-mode ruling device; the multi-mode ruling device performs consistency rulingon information distribution in a flow table of the output result set, and issues a ruling result to a switch; and after each judgment, the negative feedback mechanism adjusts the confidence of the corresponding heterogeneous SDN controller according to the ruling result, so that dynamic selection of the heterogeneous SDN controllers in the heterogeneous pool is realized, and the security defense capability of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of mimic defense, and in particular relates to a multi-mode arbitration system based on a time iteration and negative feedback mechanism. Background technique [0002] With the rapid development of network technology, SDN (Software Defined Networking) is gradually being used by major enterprises because it can reduce costs and increase flexibility. However, it will also bring new security risks accordingly. Today's response methods are still mainly through some traditional methods, but these traditional methods are extremely difficult to deal with unknown vulnerability threats. [0003] By introducing heterogeneous SDN controllers, the singleness of SDN controllers can be changed, and the overall randomness and dynamics can be increased, so as to improve the defense ability against unknown threats launched by unknown vulnerabilities. Contents of the invention [0004] Aiming at the problems existing in t...
