| Abstract(in English) | Toward efficient resource utilization, we have been tackling a SDN-enabled flow control considering application QoE. QoE helps us to handle application flows with the same basis even multiple different applications coexist on network. In this study, we estimate QoE of video streaming application based on the statistical information obtained from OpenFlow. The previous study showed that the packet loss rate is a key factor to estimate QoE on video streaming application, and proposed QoE estimation method which corrected measurement errors of OpenFlow. On the other hand, since the estimation accuracy of the previous method becomes worse in case of packet losses happening, in this study, we propose an improved QoE estimation method for video streaming that can distinguish between measurement errors and packet losses by exploiting the trend of occurrence in measurement errors. Through experiments, we showed that our proposed method can provide an QoE estimation even under the packet loss environments. |
