The IP traceback is an important mechanism in defending against distributed denial-of-service (DDoS) attacks. In this paper, we propose a probabilistic packet marking (PPM) scheme, Tabu Marking Scheme (TMS), to speedup IP traceback. The key idea of “tabu mark” is that, a router still marks packets probabilistically, but regards a packet marked by an upstream router as a tabu and does not mark it again. We study the impact of the traffic aggregation on the convergence behavior of PPM schemes. Furthermore we derive a new analytical result on the partial coupon collection problem, which is a powerful tool applicable for computing the mean convergence time of any PPM scheme. Our study shows that the idea of “tabu mark” not only helps a PPM scheme that allows overwriting to reduce the convergence time under a DDoS attack, but also ensures the authentication of the routers’ markings.
