Simulation is undertaken to study the statistics of cell loss due to congestion at the burst and cell levels. A virtual path through an ATM network is modelled as a tandem queueing network which is offered mixtures of homogeneous discrete-time burst-silence traffic with different burst lengths. Our attention is focussed on a designated traffic stream as it goes through the tandem queueing network. In the simulation, we have not introduced the 'independence assumption' between the adjacent queues, i.e. the actual tandem queueing network is used to obtain the performance measures for the designated traffic stream. Cell loss probability and high order distributions of cell loss such as cell loss-free run distribution and cell loss pattern distribution are obtained. These results present some information needed for estimation of end-to-end overall quality of service (QOS), design of the cell policing mechanism, and flow control schemes in ATM networks.
