    Abstract: For multiservice loss networks the calculation of the normalization constant is computationally impossible for realistic sized problems. This paper deals with two methods for simulating the loss probabilities in multiservice loss networks. The regenerative method is based on the regenerative nature of the process and the simulation is carried out by simulating the DTMC of the process. The second approach tries to combine the effectiveness of Monte Carlo simulation with the computational easiness of simulating the DTMC. Some considerations, on using importance sampling (IS) for increasing the efficiency of the simulations, are also given.
