Proposal of Multi-path TCP Packet Scheduler to Adjust Trade-off between QoS Fluctuation and throughput for WebQoE Improvement

This paper proposes a new MPTCP packet scheduler for improvement of Quality of Experience for a Web service (WebQoE); it suppresses the Quality of Service (QoS) fluctuation while maintaining the minimum throughput required for a Web service. The proposed scheduler adjusts a trade-off between the degree of QoS fluctuation and the throughput according to the observed Round-Trip-Time (RTT). The authors implemented the proposed scheduler and evaluated its QoS by actual experiments. The results show that the proposed scheduler could adjust the trade-off between the QoS fluctuation and the throughput.
