Advanced Packet Marking Mechanism with Pushback for IP Traceback

Distributed Denial-of-Service(DDoS) attack can be done by generating a large volume of traffic through spoofing the IP address of the target system. In response to such attacks, IP traceback technology has been proposed. The method identifies the source of a DDoS attack and restructures the path on the network through which the attacking packet has been transmitted. Existing traceback techniques marked path information on packets or generated separate traceback messages but they increase network load and cannot cope with DDoS attacks actively because they generate traceback information for arbitrary packets without identifying DDoS attacks. Thus this study proposed an improved marking technique that identifies DDoS traffics at routers by applying the pushback function and cope with DDoS attack packets efficiently. According to the result of experiments, the proposed technique reduced network load and improved traceback performance.
