The system is design to implement an identification and classification algorithm for tracing DDoS attack and multicast attack information to an edge router using Cyclical Deterministic Packet Marking (CDPM) method. Edge router registry stores the received packet IP source address and mark the packet. An Identification and classification algorithm implemented on Border gateway. An algorithm based on received packet and path variation. Border gateways analyze the packet path and number of request received from particular source address. And classify the packet if attacker multicast the attack packet information to edge router and intermediate router or if legitimate packet the border gateway allow to use server.
