A Proposal of Throughput-Based MPTCP Scheduler for WebQoE Improvement

This study proposes a new packet scheduler scheme for Multi-Path TCP to improve the user experience (WebQoE) of Web services. The proposed scheme suppresses fluctuations in MPTCP ’s quality of service (QoS) while at the same time improving QoS. This scheme estimates QoS fluctuations from the throughput measurement, and subflows that can suppress fluctuations are selected based on this estimation. The authors have implemented the proposed scheme and evaluated QoS by experiment. The experimental results show that the proposed scheme can suppress QoS fluctuations more than the existing MPTCP packet scheduler schemes in various environments, confirming the effectiveness of the proposed scheme.
