Journal on Computer Science 2347–6141 2 3 1 5 TCP Friendly, Congestion Control, Media Traffic, TFRC, NS-2 The authors are in search of a reliable, congestion control, real-time media traffic supportable protocol which is not yet available. Previously, for this purpose the authors were taking help of Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). TCP is a reliable, congestion control protocol which works fine for low bandwidth scenarios and UDP is an unreliable protocol but works fine in high bandwidth scenarios. A protocol that opts in both situations high and low bandwidth scenarios is required. One such a protocol TCP Friendly Rate Control (TFRC) is designed by Internet Engineering Task Force People (IETF) and it is a reliable, congestion control protocol. TFRC is a rate based approach and well suitable for real-time video traffic because of smooth sending rate and friendliness with TCP flows achieved in it. This paper shows the complete study of TFRC, and performance of TFRC is compared with TCP flows such as TCP SACK, TCP Vegas, TCP Reno, and TCP Tahoe and also with UDP in wired environment.
