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.
