Distributed flow control model of the App - DDoS attacks based on the credibility LONG Shi-gong [1], ZHAO Meng-long [2] (Institute of Computer Software and Theory, Guizhou University, Guizhou Guiyang, 550025)Abstract: The application layer distributed denial of service (application layer DDoS, referred to as App-DDoS) attack characteristics, combined with flow control technology, the applications of credibility and the thought of distributed processing, made Distributed flow control model of the App-DDoS attacks based on the credibility. The model calculated the credibility with the normal user's service request for data distribution and achieve flow control in different nodes of the topology network with multi-level structure,thus not only achieve the defense against the App-DDoS attack at the same time, but also reduced the impact on performance of network.
