帯域制御と優先制御を用いたWeb-QoEに基づくQoS制御を行う無線LAN基地局の開発

抄録

This paper develops a wireless LAN base station with QoS control based on Web-QoE by bandwidth control and priority control; it evaluates 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.
