  18           CCID-3 denotes TCP-Friendly Rate Control (TFRC), an equation-based
  19           rate-controlled congestion control mechanism.  TFRC is designed to
  20           be reasonably fair when competing for bandwidth with TCP-like flows,
  21           where a flow is "reasonably fair" if its sending rate is generally
  22           within a factor of two of the sending rate of a TCP flow under the
  23           same conditions.  However, TFRC has a much lower variation of
  24           throughput over time compared with TCP, which makes CCID-3 more
  25           suitable than CCID-2 for applications such streaming media where a
  26           relatively smooth sending rate is of importance.
  27
  28           CCID-3 is further described in RFC 4342,
  29           http://www.ietf.org/rfc/rfc4342.txt
  30
  31           The TFRC congestion control algorithms were initially described in
  32           RFC 5348.
