In order to make up for the gap of the existing research in the defense of unknown SDN (Software-Defined Networking) vulnerabilities

this paper proposes an SDN endogenous security control plane based on multi-dimensional heterogeneous features and feedback-aware scheduling strategy. This scheme effectively increases the spatiotemporal uncertainty of the execution body in the SDN control plane (reversing the asymmetry between attack and defense) by combining a redundant set construction strategy

a multi-dimensional heterogeneous element coloring strategy

and a dynamic feedback-aware scheduling strategy. The related simulation results show that the scheme can converge the number of executive bodies

increase the multi-dimensional heterogeneity index and reduce the global failure rate of the system.
