One of the promising applications of network virtualization is fine grained service differentiation and flexible quality of service (QoS) management. In this paper, as a lightweight technique at service-level for mo- bile network virtualization, we propose a per-service queuing at the base station to achieve above objectives. We further investigate its performance through asymptotic analysis based on the theory of large deviations. In spe- cific, we statistically characterize a general first-come first-served (FCFS) queue by three important factors: the QoS requirements, traffic models, and allocated channel capacity. Thus, the queuing performances can be derived asymptotically in terms of violation probability of the queue length and queuing delay. A theoretical comparison of them between per-service queuing and conventional per-class queuing is given. By simulations, we show that, within a reasonable range, the real traces are closely approximated by the prediction of our theoretical analysis. More- over, we demonstrate that the per-service queuing requires around 10% less wireless capacity than the conventional approach. |
