17 CCID-3 denotes TCP-Friendly Rate Control (TFRC), an equation-based
18 rate-controlled congestion control mechanism. TFRC is designed to
19 be reasonably fair when competing for bandwidth with TCP-like flows,
20 where a flow is "reasonably fair" if its sending rate is generally
21 within a factor of two of the sending rate of a TCP flow under the
22 same conditions. However, TFRC has a much lower variation of
23 throughput over time compared with TCP, which makes CCID-3 more
24 suitable than CCID-2 for applications such streaming media where a
25 relatively smooth sending rate is of importance.
27 CCID-3 is further described in RFC 4342,
28 http://www.ietf.org/rfc/rfc4342.txt
