A New Framework for DDoS Attack Detection and Defense in SDN Environment

While software defined network (SDN) brings more innovation to the development of future networks, it also faces a more severe threat from DDoS attacks.In order to deal with the single point of failure on SDN controller caused by NEFF D95BMP5N0B N70 Built In 90cm 5 Speeds A Chimney Cooker Hood Stainless DDoS attacks, we propose a framework for detection and defense of DDoS attacks in the SDN environment.Firstly, we deploy a trigger mechanism of DDoS attack detection on data plane to screen for abnormal flows in the network.Then, we use a combined machine learning algorithm based on K-Means and KNN to exploit the rate characteristics and asymmetry characteristics of the flows and to detect the suspicious flows determined by the detection trigger mechanism.Finally, the controller will take corresponding actions to defense against the attacks.

In this paper, we propose a new framework of cooperative detection methods of control plane and data plane, which effectively Vacuum Floor Nozzle improve the detection accuracy and efficiency, and prevent DDoS attacks on SDN.
