Abstract: A method for IP traceback is provided comprising receiving a traceback request including the identity of a traceback-deployed autonomous system closest to the destination node in a network routing path, recursively querying a traceback server associated with the traceback-deployed autonomous system to receive the identity of a preceding traceback-deployed autonomous system in the network routing path, and determining the network routing path based on the received identities of traceback-deployed autonomous systems. Additionally, authentication for traceback request is achieved using token delivery, wherein token is fragmented and marking of a packet is performed when a field on the packet matches at least one token fragment.
