Study on New TCP Congestion Control for Low QoS Fluctuation Based on Quality of Experience for Web Services

Abstract

This paper proposes a novel TCP congestion control based on Quality of Experience for Web services (WebQoE). The proposed method controls congestion window so that a fluctuation of QoS becomes low. In this method, a variance of RTT is estimated by using the fluctuation of QoS. The authors implement the method and QoS evaluation. The experimental results show that the proposed method can suppress the fluctuation of RTT more than TCP cubic and TCP New reno and confirms the effectiveness of the method.
