“漏桶法”流量控制的一种改进及分析

A Modification and Analysis on "Leaky Bucket Method" for Flow Control

流量控制是ATM技术的一个关键问题。针对“漏桶”模型提出了一种改进方法，其基本思想是通过增加输入数据缓冲区，来降低信元丢失率。通过计算机模拟，针对改进的漏桶法对信元丢失率、信元平均延迟、信元延迟方差带来的影响进行了定量的分析。

Flow control is an important study field in ATM. The paper proposes an improvement of Leaky Bucket Technique. The basic idea is to decrease the cell losing ratio by adding an input buffer. Through the computer simulation, a quantitative analysis is given about the influence that the modified model brings to the cell losing ratio, the cell average delay and the average delay variance.
