Proposal of Multi-path TCP Packet Scheduler to Adjust Trade-off between QoS Fluctuation and Throughput for WebQoE Improvement 査読あり国際誌

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.

Study on Depending on the OpenFlow Controller Placement of Multi-pathization Method 査読あり国際誌

This paper proposes a new method of improving multi-pathization method by only selecting the placement of OpenFlow controller. The performance of the multi-pathization is degraded by the difference in delay. The authors implemented their method by actual IoT devices and evaluate QoS by experiment. From the results of experiments, the TCP throughput when the location of the OpenFlow controller is appropriately selected is higher than that of multi-pathization method without our method. Thus, the proposed method decreases the difference in delay by replacing an OpenFlow controller adequately.

Study of Multi-Path TCP Scheduler to Suppress QoS Fluctuation for Improving WebQoE 査読あり国際誌

Kensuke Noda, Yoshihiro Ito

Proceedings of IEIE/IEEE 2019 International Conference on Electronics, Information, and Communication (ICEIC) 2019年01月

記述言語：英語掲載種別：研究論文（国際会議プロシーディングス）出版者・発行元：IEEE

This paper proposes a new packet scheduler of MPTCP to suppress Quality of Service (QoS) fluctuation for improvement of Quality of Experience for a Web service (WebQoE). The scheduler estimates the fluctuation of QoS from that of the packet delay, and preferentially sends a packet to uncongested path to suppress the fluctuation. The authors implement the proposed scheduler and evaluate QoS by experiments under various environments. From the results, they show that the proposed method deteriorates QoS but suppresses the fluctuation as compared with the default scheduler under various environments.

記述言語：日本語掲載種別：研究論文（学術雑誌）出版者・発行元：電気学会

This paper proposes a method of estimating the most appropriate transmission rate of an IEEE 802.11g wireless LAN based on QoE for Web services. The method utilizes the linear multiple regression analysis to find a formula for calculating QoE from QoS; it then estimates the most appropriate transmission rate by using the multiple regression line. This paper confirms the effectiveness of the method by experiment. In the experiment, the authors target actual two Web services, a shopping service and a map service; they consider the round trip time and the packet loss ratio as QoS parameters and treat the satisfaction as a QoE parameter. The authors performed QoS evaluation and QoE assessment. The experimental results show the appropriateness of the method.

Proposal of Novel MPTCP Congestion Control to Suppress QoS Fluctuation for WebQoE Improvement 査読あり国際誌

Kensuke Noda, Yoshihiro Ito

Proceedings of IEEE ICCE-Berlin 2018 2018年09月

記述言語：英語掲載種別：研究論文（国際会議プロシーディングス）出版者・発行元：IEEE

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.

Development of Wireless LAN Base Station with QoS Control Based on Web-QoE by Bandwidth Control and Priority Control 査読あり国際誌

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：John Willey & Sons, Inc.

This paper develops a wireless local area network (LAN) base station with quality of service control based on Web quality of experience (QoE) by bandwidth control and priority control; it evaluates the performance of the developed system by experiments with subjects. By using the relationship between importance of data of a Web service and the distribution of the length of IP packets, the base station can reduce the bandwidth consumption over a wireless LAN without worsening of QoE. The authors have implemented by adopting two technologies for priority control: OpenFlow and Wi‐Fi multimedia. In the experiment, the authors treat three actual Web services and assess QoE for them. From the experimental results, the authors show the effectiveness of the developed base station.
