8 | CCID 3 denotes TCP-Friendly Rate Control (TFRC), an equation-based | ||
9 | rate-controlled congestion control mechanism. TFRC is designed to | ||
10 | be reasonably fair when competing for bandwidth with TCP-like flows, | ||
11 | where a flow is "reasonably fair" if its sending rate is generally | ||
12 | within a factor of two of the sending rate of a TCP flow under the | ||
13 | same conditions. However, TFRC has a much lower variation of | ||
14 | throughput over time compared with TCP, which makes CCID 3 more | ||
15 | suitable than CCID 2 for applications such streaming media where a | ||
16 | relatively smooth sending rate is of importance. | ||
17 | |||
18 | CCID 3 is further described in [CCID 3 PROFILE]. The TFRC | ||
19 | congestion control algorithms were initially described in RFC 3448. | ||
