Proposal of Novel MPTCP Congestion Control to Suppress QoS Fluctuation for WebQoE Improvement
Kensuke Noda, Yoshihiro Ito · 2018
This paper proposes a new congestion control of Multi-Path TCP (MPTCP) for improvement of Quality of Experience (QoE). This method controls the congestion window for each subflow so as to suppress the fluctuation of Quality of Service (QoS). The fluctuation of QoS is estimated from that of the Round Trip Time, and the congestion window is controlled according to the estimated fluctuation. The authors implemented the proposed method and evaluate QoS by experiment. The experimental results show that the proposed method can suppress the fluctuation of QoS as compared with the existing congestion controls of MPTCP under congestion.
