本文在对VBR业务带宽需求预测的基础上 ,提出了一种综合考虑信元丢失率、信道利用率、缓冲延时和缓冲器容量需求等方面的VBR业务频带动态分配的方法。对如何确定有关控制参数等问题 ,进行了研究 ,并就运用最佳线性预测和递归最小二乘法(RLS)等估计理论 ,对VBR业务流量速率的预测和控制 ,系统的性能作了分析和模拟 Based on the prediction of VBR service bandwidth demand, this paper proposes a method to dynamically allocate VBR service bandwidth considering cell loss rate, channel utilization rate, buffer delay and buffer capacity requirements. How to determine the relevant control parameters and other issues were studied, and on the use of the best linear prediction and recursive least squares (RLS) estimation theory, the VBR traffic flow rate of the prediction and control, the system performance analysis and simulation
