摘要: 针对传统概率包标记(PPM)中存在遗失标记信息、重构困难、准确率低等问题,提出一种动态概率标记方法。运用NS2软件对相应的网络进行模拟,并在模拟环境下对传统方案及动态概率标记方法进行测试、比较和分析。仿真结果表明,该方案的路径重构效率和准确性均优于传统PPM方案。

Abstract: 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.

Key words: IP tracking, Distributed Denial of Service(DDoS), Probabilistic Packet Marking(PPM), network security
