| In this paper, in-depth analysis on stream media network transmission control is conducted based on application background of network video transmission and with aid of traditional network jamming control principle, and according to the network self-adapting jamming control model TFRC, this paper brings forward a self-adapting rate sending strategy based on server end the improved TFRC jamming control strategy. In the strategy the server end sending rate will be adjusted rationally according to the loss rate and network transmission delay jitter of the RTCP packet, which can makes up for the disadvantage of the inaccurate usable bandwidth and the high error of sending rate of the former control algorithm. The improved TFRC jamming control strategy is friendly to TCP, can lower the loss rate and minish the oscillation amplitude of the image quality of client end, keep the high usability, ease jamming and improve video transmission quality. |
