Research on Composed Packet Marking for IP Traceback Algorithm
Yan Wen-zhi · Jisuanji gongcheng · 2009
Based on the current research on improving the Compressed Edge Fragment Sampling(CEFS) algorithm of Savage,the relations among the distance of the attacking path,the statistics on the traffic of routers,marking probability are analyzed.A new approach of composed packet marking method is proposed.In the new proposal the convergence of mathematic is optimized,computational complexity and the false positive alarm for the victim to reconstruct the attack graph is reduced,a victim can construct major attacking path in minimum time.The method can be used in tracking DDoS attacks of multi-source by establishing a simulated test environment and experiment analysis.
