I'll now take a look at the other proposed TFRC DCCP CCIDs to find more code that is now in ccid3.c and move to this module, the loss event rate, calc_X, etc most probably will be moved there. The main goal of these changes is to pave the way for the implementation of more TFRC based DCCP CCIDs and to shrink ccid3.c, reducing its complexity and helping in getting it rock solid.

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.
