In recent years, Denial of Service attacks have evolved into a predominant network security threat. In our previous work, we identified the necessary building blocks for an effective defence mechanism and suggested ways to integrate them. Here, we present the results of this integration on the DoS-resilience of a real networking testbed which runs the Self-Aware CPN routing protocol. The incoming traffic at each node is monitored with a detection mechanism that is based on maximum likelihood estimation. In response to high probability of attack, the traffic is ratelimited proportionally to the measured probability. We illustrate the results of the experiments we have performed to demonstrate the efficiency of the distributed defence system that we propose.
