摘要
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 。
Based on the prediction of VBR traffic bandwidth requirement,a dynamic transmissoin rate allocation method is presented in this paper,in which the cell loss rate,the utilization of bandwidth allocated ,delay and the size of the buffer have been considered all together.This paper also gives the way to determine the control parameters .The system performance has been simulated and analyzed in which the theory of linear optimum prediction and RLS are employed to predict the flow rates of the VBR traffic.
