Robustness verification method and apparatus for distributed control plane in software-defined network
Provided are a robustness verification method and apparatus for a distributed control plane in a software-defined network, including constructing a robustness verification framework, where the robustness verification framework accommodates a failure scenario set and a failure recovery strategy set; selecting a failure recovery strategy, and querying a worst failure scenario under the failure recovery strategy; verifying a utilization rate of a biggest controller in the control plane under the combination of the worst failure scenario and the failure recovery strategy; and verifying the robustness of the control plane based on the utilization rate. The verification problem of the control plane is taken as a robustness optimization problem under different failure cases and failure recovery strategies. After the failure recovery strategy is selected, the worst failure scenario is obtained to determine whether the performance of the control plane satisfies requirements.
