The Research of DDoS Attack Detecting Algorithm Based on the Feature of the Traffic

As DDoS attacks can not be detected effectively by traditional methods in time, a DDoS attack detecting algorithm based on the relation of characteristic parameters is researched according to the analysis of the essential characteristic of DDoS. The scheme can detect a DDoS attack traffic in its early stages when the attacking packet's attribute value has no distinct features. It can differentiate DDoS from normal flash crowd traffic. The simulation shows the algorithm is more effective than traditional methods.
