Abstract

This study proposes a new congestion control scheme for multi-Path TCP to improve the user experience of Web services (WebQoE). It then studies its combination with a scheduler to suppress QoS fluctuations in MPTCP by experiment. The experimental results show that the proposed scheme suppresses throughput fluctuations, i.e., QoS fluctuations, better than existing MPTCP congestion control schemes in various environments, confirming the effectiveness of our proposal. The results also show that QoS fluctuations can be suppressed by combining a scheduler that suppresses RTT fluctuations with congestion control in specific environments.

Keywords: MPTCP, WebQoE, TCP, RTT, QoS.
