摘要

本文提出一种新的城域网介质访问控制协议──ＤＱＣＡ。在大文件传输时ＤＱＣＡ网络经过一个暂态过程后可达到公平的稳态，而这个暂态过程比ＤＱＤＢ短得多，而且网络无带宽浪费，ＤＱＣＡ城域网的带宽分配十分灵活。计算机仿真显示了ＤＱＣＡ良好的介质访问特性。

Abstract

A new medium access control protocol for MANs named DQCA（Distributed Queue Cyclic Access）is presented in this paper.When the users of DQCA MAN transfer long files

the network will reach a fair steady state which is after a transient period. There is no bandwidth wastage in the network.The transient period is shorter than that of DQDB. DQCA MAN has the flexibility in bandwidth allocation. Computer simulations illustrate the access characteristics of DQCA.
