A SIMPLIFIED PERFORMANCE EVALUATION FOR BURSTY MULTICLASS TRAFFIC IN ATM SYSTEMS

In broadband ISDN with ATM, various kinds of traffic, such as voice, d ata and video, share the common transmission resource. For such multic lass traffic systems, it is necessary to evaluate the grade of service (GOS) for individual traffic. In particular, for the ATM networks int egrating voice and video which are of bursty property and delay sensit ive, the individual performance evaluation for the mixed bursty traffi c is an important problem. In this letter, we propose a simplified eva luation of the individual mean waiting time for the bursty multiclass systems appearing in the ATM network and show numerical examples for v oice/video system.
