Abstract

Abstract: Static bandwidth resource allocation or class of services dynamic bandwidth allocation is difficult to adapt to the characteristics of service flow, and unable to ensure the QoS of all levels service. The model of traffic prediction and bandwidth allocation is designed. The method of traffic prediction and Multi-Service Traffic Prediction Dynamic Bandwidth Allocation（MSTPDBA） are proposed. MSTPDBA can reallocate the available bandwidth by the size of traffic prediction. MSTPDBA which can control the services delay and improve utilization ratio of system bandwidth is proven to be effective by simulated experiments.

Key words: Quality of Service（Qos）, class of service, interpolation prediction, available bandwidth, dynamic allocation

摘要： 静态带宽资源分配方法或基于业务分类的动态带宽分配方法等很难适应业务流特性，无法保证各级业务的服务质量。设计了流量预测及带宽分配模型，给出了流量预测计算方法，提出多业务流量预测动态带宽分配方法（MSTPDBA），该方法基于业务预测流量的大小进行可用带宽的重新分配。仿真实验证明了MSTPDBA的有效性，能控制不同业务的时延，并提高了系统带宽资源的利用率。
