  • 摘要:Transport layer protocol, for lack of effective congestion control, made an irrational bandwidth utilization ratio between UDP and TCP. Especially for streaming media transport which is easily to cause the network congestion. TFRC (TCP-friendly rate control protocol) congestion control mechanism had solved the problem effectively. However, in the high bit error rate environment of wireless network, TFPC would mistake the bit error for congestion lost packet that degrades throughput excessively. Concerning this issue, this paper put forward a self-adaptive TFRC mechanism which distinguishes congest and bit error effectively by distinguishing parameters, and adjusts the transmission rate dynamically. Simulation result reveals that self-adaptive TFRC mechanism can use link efficiently, reduce delay variation and meet the live transmission requirement of streaming media in wireless network.
