Optimal path identification to defend against DDoS attacks

A novel packet marking scheme,optimal path identification(OPi),was proposed to defend against DDoS at-tacks.Instead of using fixed 1 or 2 bit in previous schemes,in OPi a router deduces the traveling distance of an arrived packet by its TTL value and inserts a variable-length marking of 1~16 bit int...

description A novel packet marking scheme,optimal path identification(OPi),was proposed to defend against DDoS at-tacks.Instead of using fixed 1 or 2 bit in previous schemes,in OPi a router deduces the traveling distance of an arrived packet by its TTL value and inserts a variable-length marking of 1~16 bit into the packet.The marking field is filled completely even the path is very short and the distinguishability is improved.OPi outperforms previous schemes,espe-cially when attacker paths adjoin user paths seriously.To obtain better performance,an OPi+TTL filtering strategy was proposed to frustrate attackers’ tries with spoofed initial TTL values.Theoretical analyses and simulations with actual Internet topologies show OPi performs excellently.
