- CCID-3 denotes TCP-Friendly Rate Control (TFRC), an equation-based
- rate-controlled congestion control mechanism. TFRC is designed to
- be reasonably fair when competing for bandwidth with TCP-like flows,
- where a flow is "reasonably fair" if its sending rate is generally
- within a factor of two of the sending rate of a TCP flow under the
- same conditions. However, TFRC has a much lower variation of
- throughput over time compared with TCP, which makes CCID-3 more
- suitable than CCID-2 for applications such streaming media where a
- relatively smooth sending rate is of importance.
- CCID-3 is further described in RFC 4342,
- http://www.ietf.org/rfc/rfc4342.txt
- The TFRC congestion control algorithms were initially described in
- RFC 5348.
- This text was extracted from RFC 4340 (sec. 10.2),
- http://www.ietf.org/rfc/rfc4340.txt
