摘要
概率包标记(PPM)是一种有效的IP追踪技术,但传统方案基于不现实的假设,存在很多不足,影响了实用性。基于合理的假设条件改进了高级标记方案(AMS),使用可调节的标记概率,根据TTL值计算距离和点采样等策略,改善了高级包标记方案存在的弱收敛性,不支持渐进部署,易受伪造标记攻击等缺陷,具有较好的实用性。
Probabilistic Packet Marking（PPM） is an effective technique for IP traceback. However, the traditional PPM schemes are built upon unreal hypothesis, which brings out many limitations and effects their application. Based on reasonable hypothesis, Advanced Marking Scheme （AMS） was improved. With adjustable marking probability, counting distance by ＂ITL value and node sampling, the performance of AMS got improved including weak convergence, inability of incremental deployment and being vulnerable to spoof marking attack.
