DDoS attacks is the major security threats for P2P network,aiming at shortcomings of the existing DDoS attacks defense mechanism based on probability packet marking,commutating heavy,can't recognize the Disguise marked packet,proposes a modifiable probability packet marking scheme to defend against DDoS attacks,in which using modifiable probability marking method and recording IP address state in the router.The approach has the advantages of tracking large-scale DDoS attacks,distinguishing and eliminating false tag information,greatly reducing the reconstruction the number of packets to found the path of the attacking.The purpose of defending can be effectively realized.Comparing with other similar schemes,it has a stronger practicability.
