摘　　要：提出了一种离散时间情况下基于门限的ＡＴＭ漏桶算法．令牌产生池中令牌的产生速率随缓存中信元的数量而变化，信元的到达过程符合ＭＭＢＰ分布．数值分析的结果表明，影响信元丢失率的关键因素是信元缓存的体积，使用本文提出的算法。In ATM network, leak bucket is an effective method to prevent network congestion. This paper proposes a threshold based token generation scheme of the leak bucket in the discrete time case. The rate of the token generation changes according to the cell number in the buffer and the arrival process is MMBP process. The numerical results show that the cell loss probability is mainly affected by the data buffer size. In the proposed leak bucket scheme, the QoS of input traffic is satisfied with smaller data buffer and token pool size.
