^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 	  CCID-3 denotes TCP-Friendly Rate Control (TFRC), an equation-based
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 	  rate-controlled congestion control mechanism.  TFRC is designed to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 	  be reasonably fair when competing for bandwidth with TCP-like flows,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) 	  where a flow is "reasonably fair" if its sending rate is generally
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) 	  within a factor of two of the sending rate of a TCP flow under the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) 	  same conditions.  However, TFRC has a much lower variation of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) 	  throughput over time compared with TCP, which makes CCID-3 more
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) 	  suitable than CCID-2 for applications such streaming media where a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) 	  relatively smooth sending rate is of importance.
