Abstract: Aiming at there is long delay of TCP data such as control command etc in remote experiment network, a video transmission control method is presented based on Back Propagation(BP) neural network. The method estimates the network utilization using BP and regulates the transmission speed of video streaming according to the estimation and the situation of routine network load. Experimental result shows that the method can ensure reliable transmission of TCP data such as control commands.

摘要： 在远程实验网络中，控制命令等TCP数据会出现较大延迟。为此，提出一种基于BP神经网络的视频传输控制方法。利用BP对网络利用率进行估计，根据估计结果，综合网络日常负载情况，调节视频流传输速率。实验结果表明，该方法能够保证控制命令等TCP数据的及时传输。
