Feng Bo, Liu Hai, Fan Guo, Min Yu · Jisuanji gongcheng · 2011
Different from the traditional Probabilistic Packet Marking(PPM),according to the problems in PPM,such as loss of marking information,difficulty to reconstruct attack paths,low accuracy,and so on,a novel DPPM method is proposed and network simulation software (NS2) is used to verify the performance and efficiency of the method by constructing simulation environments.In comparison with PPM methods, simulation results show that DPPM has excellent accuracy and efficiency.
