The cell loss probability recommended in the B-ISDN is in the range of 10^-8~10^-12. When a simulation technique is used to analyze the performance of the ATM switching system, an enormous amount of computer time is required. In this study, we derive an importance sampling simulation technique that can be used to evaluate the loss probability in the IBP/D/1 and MMBP/D/1 queueing system. The simulation results show that the loss probability obtained by the importance sampling simulation is very close to that obtained by the ordinary simulation and the computer time can be reduced drastically by the importance sampling simulation.
