+ ---help---
+ CCID-3 denotes TCP-Friendly Rate Control (TFRC), an equation-based
+ rate-controlled congestion control mechanism. TFRC is designed to
+ be reasonably fair when competing for bandwidth with TCP-like flows,
+ where a flow is "reasonably fair" if its sending rate is generally
+ within a factor of two of the sending rate of a TCP flow under the
+ same conditions. However, TFRC has a much lower variation of
+ throughput over time compared with TCP, which makes CCID-3 more
+ suitable than CCID-2 for applications such streaming media where a
+ relatively smooth sending rate is of importance.
+
+ CCID-3 is further described in RFC 4342,
+ http://www.ietf.org/rfc/rfc4342.txt
+
+ The TFRC congestion control algorithms were initially described in
+ RFC 5348.
+
+ This text was extracted from RFC 4340 (sec. 10.2),
+ http://www.ietf.org/rfc/rfc4340.txt
