| 摘 要： | 建立了PPM算法的通用数学模型,提出了一种新的基于节点采样的IP追踪方案。该方案采用新的标记信息编码机制,解决了传统包标记方案中由于地址分片带来的组合爆炸和误报率高的问题,标记过程以AS路径代替传统的IP路径,使用最优标记策略,使得路径重构过程具有更低的计算复杂性和更短的收敛时间。仿真分析表明,此方案具有应对大规模DDOS攻击源追踪的有效性和实时性。

| Abstract: | A general mathematical model of PPM scheme is established.A novel probabilistic packet marking scheme for IP traceback is proposed,which is based on AS-level node probabilistic samping mechanism.In the scheme,using a new encoding scheme,we mitigate the high false positives incurred by combinatorial explosion significantly resulted by marking information fragment.More lower computational complexity and convergence time are obtained by reconstructing AS-level path instead of router-level path and applying opt... |
