Abstract:
Software-Defined Networking (SDN) is an architectural
approach that fulfils the requirement of high bandwidth
and the dynamic nature of current applications. One of the
key features of the SDN architecture is the separation of the
control logic from data plane devices. This key feature introduces
a new type of control traffic in the SDN architecture, which
opens the space for new vulnerabilities to SDN-based networks.
In this paper, we first present an attack model to exploit the
control channel of the SDN architecture. We then experimentally
evaluate the impact of the attack on the end-users of the SDNbased
network using our physical experimental testbed. Our
experimental results clearly show that the control channel DoS
attack has a major impact on the end-users of the SDN-based
networks.
