Throughput-sensitive multimedia applications, such as on-demand video streaming and non-interactive live streaming require a high sending rate and a certain-level of smoothness. On the other hand, interactive streaming such as on-line conferencing requires a smooth sending rate. TFRC and TFWC support smoothness-sensitive multimedia applications, however, they cannot provide enough sending rate to throughput-sensitive multimedia applications. In this paper, we propose Tunable TFWC (TTFWC), an extension to TFWC to achieve various throughput behavior with regard to trade-off between smoothness and the sending rate based on application requirements. TTFWC supports throughput-sensitive multimedia applications in addition to smoothness-sensitive applications. Simulation results show that TTFWC with the value of tuning parameter 0.9 achieves approximately 10% higher throughput than the original TFWC without compromising TCP-Friendliness.
