Abstract:The defense of DDoS attacks has become the difficult area in network security.The
proposed scheme can prevent DDoS attacks roundly and actively.It implements detector based on RBF-NN to detect DDoS attacks ,and the precise can reach 97.9%;implements an IP traceback scheme with packet marking in blocks,which provides higher precision and more efficient computation;implements a novel approach named Packet funneling to mitigate DDoS attacks,it ensures the quality of service. The technology of the scheme is practical and easy to
deploy,low price,it has the very good application prospect.
