摘　　要：ATMDQDB城域网可以采用纯ATM方式支持综合业务，本文着重研究ATMDQDB城域网中的恒定比特率业务的性能，用一个四维Markov链来描述网络中某一标记节点的状态，给出了稳态方程和排队长度的幸存函数。本文的分析方法和结果已用于"宽带光纤区域网原理模型"科研项目中的缓存容量设计。The ATM DQDB MAN can provide integrated services with pure ATM method which transfers any kind of services in an unified manner. This paper analyzes the performance of the CBR services in the ATM DQDB MAN. A four-dimensional Markov chain is used to describe the steady state of a tagged user and the survivor function of the queue length distribution is calculated to design buffer capacity of the tagged user. The analytical method and results have been applied to the design of our experimental network.
