摘　　要：该文对ATM网络的CBR、VBR、ABR三种业务类型采用分组延迟时间作为评价指标,考虑到服务质量指标QoS对网络性能的影响,建立了基于QoS参数的ATM网络性能评价模型,并给出了相应的解析式。利用计算机仿真方法对该模型进行仿真试算,结果表明这种性能评价模型基本可用。In this paper,a new performance evaluation model which is concerned with CBR?VBR?ABR services of ATM is built up by using latency time as a parameter and taking account of the influence of QoS(Quality of Service).Some equations are also proposed.The results of computer simulation show that this model is available.
