摘要
本文分析了ATMDQDB城域网中恒定比特率业务的时延特性，恒定比特率业务比可变比特率数据业务的优先级高，但两者都采用统一的分组方式进行传输。本文的分析表明，在业务负荷不是非常重的情况下，恒定比特率业务的时延性能还是令人满意的，从而证明了ATMDQDB城域网的可行性。
The delayed time of the constant-bit-rate (CBR) services in the ATM DQDB MAN is studied in this paper. The ATM DQDB MAN transfers any kind of services in an unified manner with CBR services af higher priority and variable-bit-rate (VBR) data services at lower priority. The results indicate that the delay performance of the CBR services is satisfactory in the ATM DQDB MAN if the network is not overloaded seriously.
