Improved method of TCP-friendly congestion control protocol
对TCP-friendly拥塞控制协议的一种改进

TCP Friendly Rate Control (TFRC) is a congestion control mechanism designed for non-TCP flows. Due to that not all losses are related to congestion in wireless network, to adopt initial TFRC will induce maloperations. In the paper, biased queue method was used to distinguish congestion losses from random losses. It would prevent unnecessary congestion control and would improve the quality of transmission in wireless networks. Through simulations and experiments, it is found that the method can greatly improve the stability of transport rate, finally accomplishes QoS of application layer.
