| Abstract: | Abstract. This paper presents a Media- and TCP-Friendly Rate-based Congestion Control algorithm (MTFRCC) for scalable video streaming in the Internet. The algorithm integrates two new techniques: (i) the use of a utility-based model for the target system combined with the rate-distortion function as the application utility measure for optimizing the overall video quality; and (ii) a two-timescale approach of rate averages (long-term and short-term) to satisfy both media and TCP-friendliness. We use simulations to evaluate our algorithm and compare the results against the state-of-the-art TCP-Friendly Rate Control (TFRC) algorithm. We consider five criteria to assess the MTFRCC algorithm, namely: TCP fairness, responsiveness, aggressiveness, overall video quality, and smoothness of the resulting bit rate. Our simulation results manifest that MTFRCC performs better than TFRC for various congestion levels, including improvement of the overall video quality. |
