Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention.
Fig. 1 is a block diagram of a multi-mode arbitration system based on time iteration and negative feedback mechanism according to the present invention, the multi-mode arbitration system includes: the system comprises a heterogeneous pool unit, a multimode arbitrator and a negative feedback unit; the heterogeneous pool unit contains more than 3 heterogeneous SDN controllers; in each SDN control layer, a heterogeneous SDN controller is used for simultaneously processing input requests, and an output result set of each SDN controller in unit time is submitted to a multi-module resolver; the multi-mode arbitrator carries out consistency arbitration on the information distribution in the flow table of the output result set and sends the arbitration result to the switch; and after each judgment, the negative feedback unit adjusts the confidence of the corresponding heterogeneous SDN controller according to the judgment result, so as to realize the dynamic selection of the heterogeneous SDN controller in the heterogeneous pool unit. And recording the output result and the arbitration result of each SDN controller.
The specific operation process of the multi-mode arbitration system is as follows:
the method comprises the following steps: and in unit request processing time, randomly selecting N SDN controllers (N is larger than or equal to 3) from the heterogeneous pool unit according to weight values, and if m SDN controllers meeting multiple decision results exist in the last unit request time, selecting N-m SDN controllers from the heterogeneous pool unit.
The SDN controller in a heterogeneous pool unit needs to comply with the following requirements:
1. the SDN controllers in the heterogeneous pool units are SDN controllers with completely different structures and equivalent functions;
2. the number of the heterogeneous SDN controllers which process the input requests simultaneously by using the heterogeneous SDN controllers is at least 3, and the number of the SDN controllers in each time of processing the input requests is smaller than that of the heterogeneous SDN controllers in the heterogeneous pool unit.
The SDN controllers with the heterogeneous structures have different structural compositions and implementation principles, but have the same outputs with the same effect for the same inputs, that is, each SDN controller has a unique vulnerability and backgate, and thus the SDN controllers with the completely different architectures may not simultaneously fail the heterogeneous SDN controllers with the same functions under the same attack. In each request processing period, the arbitrator judges only two possibilities according to the result of arbitrating the similarity, wherein the similarity is greater than or equal to the threshold, or the similarity is less than the threshold, so that in order to guarantee the feasibility of each multi-arbitration, it is necessary to guarantee that the number of heterogeneous SDN controllers participating in the request processing must be greater than the number of possibilities, that is, not less than 3. In addition, the number of heterogeneous SDN controllers represents the diversity of the system, and it can be intuitively considered that the sensing accuracy of the threat is improved by increasing the number of heterogeneous SDN controllers in a unit request processing period, but the working cost of the system is increased at the same time.
Step two: for the same request, the request is distributed to a plurality of SDN controllers selected from the heterogeneous pool at the same time and then processed, a processing result and a set of output results of the SDN controllers in unit time are submitted to the multi-mode resolver, and meanwhile, the output result of each heterogeneous SDN controller is recorded.
Step three: the multimode arbitrator performs consistency arbitration on information distribution in the flow table of the output result set, and the method specifically comprises the following steps: and drawing flow table information distribution in unit time, calculating distribution similarity by the multi-mode arbitrator, performing multi-arbitration to output arbitration results, recording the arbitration results, and issuing the arbitration results to the switch.
Drawing flow table information distribution to perform statistics on the contents of the flow table in the SDN controller, including but not limited to match fields and events;
calculating the similarity is to calculate the mutual similarity of the content distribution of the flow table information by a similarity calculation method;
and if the similarity of the output results of more than half of the heterogeneous SDN controllers is judged to be greater than or equal to a specified threshold value, issuing the calculation result of the SDN controller with the highest weight value in the SDN controller to the router.
Step four: after each arbitration, the negative feedback unit adjusts the confidence of the corresponding heterogeneous SDN controller according to the arbitration result, and records the output result and the arbitration result of each SDN controller, as shown in fig. 2; the specific method comprises the following steps: counting the resolution result of the resolver, and taking the SDN controller with the largest weight value in the SDN controllers which meet the requirement as one of the SDN controllers selected in the next request processing period; and in addition, the similarity of the judgment result is calculated, and the negative feedback unit judges whether the SDN controller in the request processing period needs to be cleaned and reset according to the similarity statistics. If the similarity is smaller than the threshold, the SDN control is required to be cleaned and the weight value is required to be reset, and the SDN control is placed in the heterogeneous pool unit again after the operation is finished. If the similarity is greater than or equal to the threshold, adjusting the weight of the SDN controller, if the weight exceeds the maximum value, not changing the weight, otherwise, increasing the weight.
