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.
