MIND: Message Classification Based Controller Scheduling Method for Resisting DDoS Attack in Software-Defined Networking

Distributed Denial of Service (DDoS) is quite a serious security issue existing in Software-Defined Networking (SDN). In order to mitigate DDoS attack, we present MIND, a message classification based controller scheduling method, where how to store and process messages is designed based on analyzing and classifying the OpenFlow messages received by SDN controller. The experiment results validate that the proposed controller scheduling method can significantly improve the availability of SDN controller under DDoS attack.
