Streaming Video Over TFRC With Linear Throughput Equation
The TCP-Friendly Rate Control (TFRC) protocol manifests strong equality towards competing TCP or TCP-friendly flows. Although the RFC 3448 suggests that TFRC is suitable for multimedia, this equality is a great disadvantage in the case of transmitting multimedia over the TFRC. The TFRC emulates TCP-like congestion control using the TCP throughput equation. In the paper, the authors substitute the TCP throughput equation recommended for the TFRC with a linear throughput equation. Simulation results show that the proposed solution is more suitable for multimedia than the equation proposed in RFC 3448. Experiments were carried out using an event-driven ns-2 simulator, developed in U. C. Berkeley.
