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 [CCID 3 PROFILE]. The TFRC
|
||
|
|
congestion control algorithms were initially described in RFC 3448.
