Internet Protocol trace back System for Tracing Sources of DDoS Attacks and DDoS Detection in Neural Network Packet Marking

Internet Protocol (IP) trace back system is the enabling technology to control Internet Crime. In this paper, we present a novel and practical IP trace back system called Neural Network Based Packet Marking (NNPM).The NNPM shows to calculate time for better tracing performance compare with FDPM and the NNPM Algorithm provides innovative features to trace the source of IP packets and can obtain better tracing capability compare with FDPM.It also adaptively changes its marking rate according to the load of the participating router by flexible flowbased marking scheme. Evaluations on both simulation and real system implementation demonstrate that NNPM requires a moderately small number of packets to complete the trace back process. The motivation of this trace back system is from DDoS defencse.It has been used to not only trace DDoS attacking packets but also DDoS Detection. It has a wide array of applications for other security systems. And comparison the algorithms on the basis of the time
