Abstract(in English) Adaptive video streaming using HTTP has attracted considerable attention because it enables continuous video viewing despite variable network conditions by utilizing prevailing HTTP infrastructure. However, since the quality of video content depends on the bandwidth used for sending it, the person receiving it may end up watching content with quality lower than if more bandwidth had been used. In this paper, a congestion avoidance method in multi-server adaptive video streaming is proposed. The proposed algorithm increases the video quality for all receivers by efficiently combining an adaptive playout bitrate switching function and a congestion-aware server selection function. Network congestion was classified into three types, and the performance of the proposed algorithm was evaluated for several cases by using a network simulator based on NS-3.13. The results demonstrated that the two functions adapted effectively to the network conditions and that the video quality of the receivers overall would therefore be improved with minimum replay interruption.
