Leveraging inter-controller communication to MitigateDDoS attacks in SDN networks

摘要

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.
