  • Abstract This thesis studies the technique of probabilistic packet marking. The main purpose of this marking technique is for the receiver to trace the true sources of the marked packets and rebuild their paths rapidly. In this thesis, we will introduce the current IP traceback mechanisms and discuss the advantages and drawbacks of these mechanisms. In these schemes, to compute marked packet number is their designed goal for the receiver. Marked packets from the marking router are overwritten by other marking routers because of the nature of probabilistic packet marking in each router. Although some IP traceback schemes can improve the overwriting problem, they usually make unrealistic assumption or do not consider the load balancing issue of the routers. In probabilistic packet marking, how to reduce the re-mark problem and how to balance routers’ overhead are two important design considerations. A scheme is proposed in this thesis to address these problems in probabilistic packet marking. Using computer simulation, we observe that our scheme can greatly decrease re-marking. When compared with the current IP traceback schemes, our scheme can reduce 65% marked packets than the other scheme from the receiver received. Moreover, the overhead of marking packet in each router is even out in the proposed scheme than the other.
