Abstract:
Video streaming has become the major source of Internet traffic nowadays. In addition, content delivery network providers have adopted Video over HTTP/TCP as the preferred protocol stack for video streaming. In our previous work, we have shown how TCP variants play a definite role in the quality of video experience. In this paper, we research several mechanisms within TCP slow start phase to enhance video streaming experience. We utilize network performance measurers, as well as video quality metrics, to characterize the performance and interaction between network and application layers of video streams for various network scenarios. We show that video transport performance can be enhanced with small changes in TCP Slow Start.
