Abstract

We present TFWC, a TCP-friendly window-based congestion control mechanism for real-time multimedia streaming applications. Although TFRC is regarded as a de facto standard for those types of applications, under low stat-mux conditions fairness can be an issue. We re-introduce a TCP-like ACK mechanism while retaining the TCP throughput equation to compute the sending rate. We show that our proposed protocol is fairer than TFRC when competing with TCP flows under certain circumstances.
