The paper proposes two schemes which enhances the performance of PPM in following aspects. Because of ingenious design, the schemes can be used to tackle large-scale DDoS. And due to adopting varational probabilistic packet marking, they can recognize and eliminate spoofed marking inscribed by the attacker intentionally. By recording the state of IP address transmission in router and transmiting the packets fragments in order, the schemes can significantly reduce the number of packets required for path reconstruction.
