Modern switching system which employ common control or central processing .architecture can be tested by load simulation. Practical traffic problems are quite often too complex for solution by theoretical analysis alone. The difficulty is due to a large number of parameters, to be handled for modelling realistic traffic. Analytical method fails to deal realistically with large number of specific operational characteristic, along with user's behavior. This thesis models the realistic traffic and generates it to the simplified switching model consisting of two queues. In order to observe what is happening inside the exchange a macro for monitoring the traffic is provided. As the system is structurally designed, it is flexible and expandable. The software has wide range of capability to replicate the user's behavior and to intermix different classes of traffic. It is applicable in the performance evaluation of realistic multislot traffic. The effect of reattempts and trunk reservation · parameters in the bandwidth allocation strategies are observed using the simulator.
