| Abstract(in English) | In recent years, video streaming services using TCP as a transport layer protocol represented by YouTube have been popular, with rapid increase of the network bandwidth. Congestion control of TCP increases the congestion window until a packet loss is detected. Therefore, the video streaming over TCP sends packets to a network at a higher speed than the video playback speed that takes the bandwidth of other competing traffic unnecessarily. In this report, we first investigate the data transfer mechanism of existing video streaming services using TCP and show that the existing video streaming services perform data transfer at the extremely higher rate than the video playback speed. Then, we propose the data transfer mechanism for video streaming over TCP that does not take the network bandwidth excessively by controlling the data transfer at an application layer. The proposed mechanism acquires the TCP state variables from the source host TCP, and estimates network congestion status. Moreover, the amount of buffered video data is acquired from a destination host. By adjusting the amount of data passed to a source host TCP in one round-trip time based on the network congestion status and the amount of buffered video data, the proposed mechanism controls the data transfer speed. Simulation results show that the proposed mechanism decreases the frequency of buffer underflow at the destination host, and does not take the bandwidth of background traffic. |
