Abstract

In this letter we present fairness performance comparison between HSTCP with DropTail router and that with AQM router. With the assumption of synchronous feedback, the RTT unfairness of TCP AIMD congestion avoidance algorithm is obvious. However, the RTT unfairness may be exponential increased in HSTCP with DropTail router. By constructing the duality model of HSTCP with AQM router, we highlight that AQM can improve the fairness performance of HSTCP. Our quantitative result shows that the unfairness of HSTCP/AQM is inverse proportional to its RTT. The insight is validated by NS2 simulation.
