TCP friendly rate control(for short TFRC) can not differentiate the reason of packet losses,has low bandwidth utilization rate,and has slow reaction to the state change of network TFRC BMN.The algorithm is presented combineing the queue length of middle node to divided among the current network state,it differentiates the wireless packet losses from the congestion packet losses by the network state,and take different rate adjustment mechanism according to different lost package reason.In addition,because the thought of multiplicative increase multiplicative decrease(for short MIMD) is quoted,the algorithm can fast response when the network into or out of congestion state.Experiments show that the algorithm's performance are improved in wireless network,meanwhile response speed of network congestion is improved.
