Mobile Agents and Packet Marking for Real-Time IP Traceback

Internet and computer technology are increasingly being used as vehicles for an escalating variety of infringements. The most popular attack on the Internet being the Denial of Service (DoS) attack, there is growing need to be able to track the sources of the attacks. IP trace back schemes can be used for tracing the source of attacks. We propose a mechanism for IP trace back which is based on packet marking and mobile agents whereby routers mark the packets in flight with only 37 bits of data and mobile agents use this information to trace back the source of attack.
