8 CCID 3 denotes TCP-Friendly Rate Control (TFRC), an equation-based
9 rate-controlled congestion control mechanism. TFRC is designed to
10 be reasonably fair when competing for bandwidth with TCP-like flows,
11 where a flow is "reasonably fair" if its sending rate is generally
12 within a factor of two of the sending rate of a TCP flow under the
13 same conditions. However, TFRC has a much lower variation of
14 throughput over time compared with TCP, which makes CCID 3 more
15 suitable than CCID 2 for applications such streaming media where a
16 relatively smooth sending rate is of importance.

18 CCID 3 is further described in [CCID 3 PROFILE]. The TFRC
19 congestion control algorithms were initially described in RFC 3448.
