An adaptive neural network model is proposed to adaptively predict the rate of variable bit rate video traffic, and the training and structure optimization of the tap delay neural network is performed by adaptive learning and pruning algorithm based on recursive minimum variance. It shows that this model can realize the high-precision prediction of complex video traffic sequence and meet the real-time and fast prediction requirements.
