摘要
针对动态概率包标记方法中标记空间受限问题,在现有动态概率算法的基础上,将动态概率包标记与多条标记思想相结合,设计了一种新的多条标记方法:n倍多条标记方法来完成IP追踪过程,并设计了相应模拟实验来测试该方法。实验结果表明,该方法完成IP追踪所需攻击包数是现有动态概率包标记方法的1/n。实验测试表明,n倍多条标记方法具备良好的可行性,可有效追踪ICMP洪水攻击。
Aiming at the problem of limited marking space existing in DPPM, a new packet marking method known as n-Muhi-DPPM is proposed, and this method, in combination of dynamic probabilistic algorithm and multi- tags marking technology based on DPPM, implements IP traceback. Then a simulation experiment is designed to test n-Muhi-DPPM, and the experiment results indicate that the number of packets needed for implementing IP traceback under n-Multi-DPPM is 1/n of the number of packets under DPPM. Thus, n-Muhi-DPPM is of good feasibility and could trace ICMP flood attack efficiently.
