TCP-Friendly Rate Control

TFRC (TCP-Friendly Rate Control is a useful congestion control technique evolved for unicast flows operating in an internet environment. This technique is introduced for applications which use a fixed packet size. It alters their sending rate in packets per second in response to congestion. The TFRC is the receiver-based technology which works with the calculation of the congestion control information in the data receiver instead of data sender.
It is the best option for the applications where the sender is the large server controlling a number of concurrent connections wherein the receiver possesses plenty of memory and CPU cycles for computation.
