  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.
  26
  27           CCID-3 is further described in RFC 4342,
  28           http://www.ietf.org/rfc/rfc4342.txt
  29
  30           The TFRC congestion control algorithms were initially described in
  31           RFC 5348.
