摘要
Ｎ＊Ｂｕｒｓｔ／Ｄ／１／Ｋ随机服务系统，是在研究ＡＴＭ网络中的流量控制问题时被广泛采用的排队模型．在小缓冲容量区域内，该排队模型的丢失率随缓冲容量改变而变化的曲线可以用一个负指数函数来描述，为此，本文直接根据无缓冲单元和只有一个缓冲单元时的丢失率确定该曲线，从而使该排队系统在小缓冲容量时的丢失率分析非常简捷．模拟实验表明：该方法非常精确．
N#Burst/D/1/K is widely used in the study of traffic control in ATM networks.In small buffer capacity region,a minus exponential function can characterize the curve of the loss probability changing with buffer size in this qUeueing model.So the curve can be obtained directly using the loss probability without buffer and that with one buffer,thus making it very simple to analyze the loss probability with small buffer capacity.Simulation shows that this approach is very accurate.
