具有质量控制功能的ATM交换节点的性能分析

本文提出一种用于ＡＴＭ网的质量控制方法－动态到达控制（ＤＡＣ），分析了采用ＤＡＣ的ＡＴＭ交换节点中，各类业务信元的丢失概率和平均时延，分析结果表明，ＤＡＣ是一种有效的质量控制方式，它能够提供多种服务等级以满足不同的需要，减小所有信元的平均时延，提高系统的有效吞吐量。

Performance Analysis of ATM Switching Nodes with Quality Control Function

In this paper,we propose a quality control method-DAC for ATM networks and evaluate the performance of cell loss probability and mean delay of each cell class in an ATM switching node. Results show that DAC is an effective quality control method and can provide several quality classes to satisfy the different requirements.The mean delay of all cells can be reduced and the effective throughput of the system can be improved by using DAC.
