摘　　要：信元丢失率分析是研究ＡＴＭ网络中流量控制问题的关键，实际应用需要我们找到一种既精确又容易实现的分析方法。本文提出了一种基于利用两状态ＭＭＤＰ近似实际输入过程的新的分析方法，通过采用一种确定ＭＭＤＰ参数的新方案，不仅得到了突发级信元丢失率与缓冲容量之间关系的解析式，而且模拟结果表明：其分析结果非常精确。The analysis of cell loss rate is the key problem in the study of traffic control in ATM networks, an effective approach is urgently needed, which not only is accurate but also can be easily carried out. In this paper, a novel approach is presented based on approximating the actual input process with a two state MMDP,by a new scheme to determine the MMDPs parameters, we obtain the analytical expression of the relation between burst level cell loss rate and buffer size, and simulation shows it is very accurate and practicable for all traffic.
