   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.
