ddebc973 | 18 | CCID-3 denotes TCP-Friendly Rate Control (TFRC), an equation-based |
7c657876 ACM |
19 | rate-controlled congestion control mechanism. TFRC is designed to |
20 | be reasonably fair when competing for bandwidth with TCP-like flows, | |
21 | where a flow is "reasonably fair" if its sending rate is generally | |
22 | within a factor of two of the sending rate of a TCP flow under the | |
23 | same conditions. However, TFRC has a much lower variation of | |
ddebc973 GR |
24 | throughput over time compared with TCP, which makes CCID-3 more |
25 | suitable than CCID-2 for applications such streaming media where a | |
7c657876 ACM |
26 | relatively smooth sending rate is of importance. |

ddebc973 | 28 | CCID-3 is further described in RFC 4342, |

31 | The TFRC congestion control algorithms were initially described in | |
4dbc242e | 32 | RFC 5348. |
