| 摘 要： | 通过实验表明,动态地根据实时视频流的低频信号部分进行带宽“在线”预测和调整,在网络利用率方面远优于根据视频流峰值速率进行的静态带宽分配。文中着重分析比较了以下两种带宽预测算法:(1)AR时间序列模型;(2)改进型BP神经网络模型。

| Abstract: | The paper presents through experiments that when we predict the on - line bandwidth for transport of real -time video, the ATM network resource can be better utilized than static bandwidth allocation which is based on peak input rate. We emphatically analyze two kinds of bandwidth prediction: (1) Autoregressive(AR) model; (2) A novel BP neural network model. |
