<p><b>Abstract</b>—Tracing DoS attacks that employ source address spoofing is an important and challenging problem. Traditional traceback schemes provide spoofed packets traceback capability either by augmenting the packets with partial path information (i.e., packet marking) or by storing packet digests or signatures at intermediate routers (i.e., packet logging). Such approaches require either a large number of attack packets to be collected by the victim to infer the paths (packet marking) or a significant amount of resources to be reserved at intermediate routers (packet logging). We adopt a hybrid traceback approach in which packet marking and packet logging are integrated in a novel manner, so as to achieve the best of both worlds, that is, to achieve a small number of attack packets to conduct the traceback process and a small amount of resources to be allocated at intermediate routers for packet logging purposes. Based on this notion, two novel traceback schemes are presented. The first scheme, called <it>Distributed Link-List Traceback</it> (DLLT), is based on the idea of preserving the marking information at intermediate routers in such a way that it can be collected using a link list-based approach. The second scheme, called <it>Probabilistic Pipelined Packet Marking</it> (PPPM), employs the concept of a "pipeline” for propagating marking information from one marking router to another so that it eventually reaches the destination. We evaluate the effectiveness of the proposed schemes against various performance metrics through a combination of analytical and simulation studies. Our studies show that the proposed schemes offer a drastic reduction in the number of packets required to conduct the traceback process and a reasonable saving in the storage requirement.</p>
