分析了高速通信网络不同业务类型的特点．根据不同业务对网络服务质量（ＱＯＳ）的要求及动态占用带宽的优先度，将其分为两种类型：一类业务可在预定的范围改变其传输速率，另一类是被动的，网络根据可用带宽的大小动态地调节其传输速率．文中给出了一种业务流量控制模型，该模型把带宽的高效率利用归结为如何对被动业务流量进行控制．按充分利用信道容量的原则，提出了一种自适应反馈控制算法．模拟表明，这种控制方法有良好的性能．
The characteristics of different service types in high-speed communication network are analyzed. According to different business requirements for network quality of service (QOS) and the priority of dynamically occupied bandwidth, it is divided into two types: one type of service can change its transmission rate within a predetermined range, the other is passive, The available bandwidth size dynamically adjusts its transfer rate. In this paper, a model of traffic control is proposed, which reduces the efficiency of bandwidth usage to how to control the passive traffic. According to the principle of making full use of channel capacity, an adaptive feedback control algorithm is proposed. Simulation shows that this control method has good performance.
