Distributed Collaborative DDoS detection method based on traffic classification features

摘要

This paper classifies the DDoS attack prevention technology from the view of defense stage and defensive position. DDoS attacks have relatively low proportion of normal flow in the boundary network at the attack traffic, and the characteristics of the network are not very obviously. For these characteristics, design and implement collaborative detection of DDoS attacks method are proposed. Simulation results show that the distributed collaborative DDoS detection method has good timeliness, accuracy and scalability than the single-point detection and route-based distributed detection scheme.
