New scheme of Probabilistic Packet Marking with compensation for IP traceback
LI Dian-bi · Computer Engineering and Applications Journal · 2008
Denial of Service attack is among the hardest network problems.Probabilistic Packet Marking(PPM) is an efficient and practical scheme.However,there exits the weakest link problem in most schemes and this problem causes the poor convergence.A new scheme of PPM with compensation for IP traceback is presented in this paper.The convergent amount of marked packets required for path reconstruction and the computation overhead are both efficiently improved,and the efficiency of path reconstruction is increased.
