QoSoDoS: If You Can't Beat Them, Join Them!

The authors present QoSoDoS, a protocol that ensures QoS over a DoS-prone (Best-Effort) network. QoSoDoS ensures timely delivery of time sensitive messages over unreliable network, susceptible to high congestion and network flooding DoS attacks. QoSoDoS is based on scheduling multiple transmissions of packets while attempting to minimize overhead and load, and avoiding self-creation of DoS. They present a model and initial empirical results of QoSoDoS implementation. Their results show that under typical scenarios, QoSoDoS can handle high congestion and DoS attacks quite well.
