Abstract

The invention discloses a multi-mode decision negative feedback system based on a multi-objective optimization algorithm. The multi-mode decision negative feedback system comprises a multi-mode decision module and a negative feedback optimization module, the multi-mode decision module comprises a heterogeneous pool unit and a multi-mode decision device; the heterogeneous pool unit comprises at least three heterogeneous SDN (Software Defined Network) controllers; a multi-mode decision device carries out consistency decision on information distribution in a flow table of an output result set of the heterogeneous SDN controller; when the multimode arbiter finds disturbance, the multimode arbiter transmits an arbiting result and information distribution in a flow table of an input set of the heterogeneous SDN controller to the negative feedback optimization module, and dynamically adjusts the selection weight of the heterogeneous SDN controller through a multi-target optimization algorithm; a better selection strategy is generated for factors such as total confidence, SDN controller processing time, cleaning duration, stability of the processing duration, resource consumption cost and the like to resist disturbance of a multi-mode resolver, dynamic selection of the heterogeneous SDN controller 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 adjudication negative feedback system based on a multi-objective optimization algorithm. Background technique [0002] With the rapid development of network technology, SDN (Software Defined Network) can improve the running speed of the network because it can deploy, manage and program the network. In this centralized network management approach, the basic network infrastructure and applications are separated from each other. It is gradually used by major enterprises. However, the current SDN controller is basically unable to take effect on the response countermeasures to unknown vulnerability threats, and cannot make corresponding dynamic adjustments. [0003] The singleness of the SDN controller is changed by introducing a heterogeneous SDN controller, and a multi-objective algorithm is introduced to dynamically change the selection strategy of ...
