<p>PURPOSE:To evaluate the traffic characteristic of an ATM (asynchronous transfer mode) exchange by instructing the start/stop of generation of a generating pattern to a cell pattern generating circuit according to the simulation model condition and applying statistic processing. CONSTITUTION:A simulation model 4 gives the instruction of generating pattern such as exponential distribution or geometrical distribution to pattern specification circuits 11, 21-n1 of cell pattern generating circuits 1, 2-n via an interface circuit 6. Then the information according to the simulation model condition such as occurrence or relinquish, etc., of a call generated by the simulation model 4 is fed to each of cell transmission circuits 12, 22-n2 to apply cell transmission/stop individually. The sent cell is stored in a memory 3 by each time. Then the simulation model 4 recognizes the arrival state of the cell from the memory 3 via an interface circuit 5 to apply statistic processing. Thus, the traffic characteristic of the ATM exchange is evaluated.</p> |
