Defending Against LDoS Attacks Using Fair AQM

Abstract

According to the instant high rate and high intensity of LDoS attacks, this paper explores using fair queue management mechanism to mitigate their effect. We perform simulation experiments to evaluate the performance of fair AQM FRED and CHOKe under LDoS attacks. The simulation results show that they are able to reduce the impact of the attacks in various degrees. FRED outperforms CHOKe in throttling the attacks, but it is slightly inferior to CHOKe in time performance.
