| 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. |
