Abstract :
We investigate via computer simulations the statistical multiplexing and admission control for multiclass Markovian sources in a buffer partitioned with J - I thresholds to provide the J loss priorities. Through heuristic conjecture and numerical analysis, the effective bandwidth concept has been extended to the partitioned buffer system, where the traffic is generated by multiclass Markov-modulated fluid sources [Y. Cheng et al., Nov. 2002]. In this paper, the packet loss probabilities in a partitioned buffer system are estimated by computer simulations. The simulation results verify that the effective bandwidth proposed in [Y. Cheng et al., Nov. 2002] can be used for efficient resource allocation while satisfying the quality of service (QoS) requirements. We use importance sampling whenever applicable to improve the simulation accuracy.
