In this poster, we propose leveraging intercontroller communication between two or more controllers in Software Defined Networks (SDNs) to inform other controllers about potential attacks so that they can proactively apply a mitigation strategy. We demonstrate and measure the effectiveness of our method by running a series of tests in an emulated network. We analyze our test results in terms of reducing the overall detection interval for a SDN with multiple controllers. Our testing indicates that inter-controller communication allows pre-emptive mitigation of Distributed Denial of Service (DDoS) vectors.
