基于缓冲区门限的ATM网业务流量控制分析

ＡＴＭ网中许多流量控制策略是基于缓冲区门限的，即根据缓冲区占有情况采取输入业务降速等控制。但以往的文献对这类控制策略的分析缺乏普遍性。本文对这类控制策略建立数学模型，并利用推广的流体流法对Ｏｎ－Ｏｆ业务在这种控制策略下的性能进行理论分析。文中通过数值实验得到一些重要结论。它们对这类控制策略的实现具有指导意义。

Analysis for Traffic Control Schemes based on Thresholds of Buffer in ATM Networks

There are many traffic control schemes based on thresholds of buffer in ATM networks, which will be active to decrease the traffic rate according to the buffer occupancy. But the analysis for them in the literature have some limitations. In this paper, this kind of control schemes has been modeled, and analysis for them has been given using extended fluid flow method. Several conclusions have been drawn from the numerical experiments and simulations. These conclusions will be helpful to implement this kind of traffic control schemes.
