Pre-print A New Paradigm for Prioritizing Multiple Class Services in Optical Burst Switched Networks

Abstract. Quality of service (QoS) differentiation within the optical infrastructure is under constant development due to the direct impact of the ever-rising demand for time-critical and multimedia applications in the Internet. In this paper, we propose an efficient prioritized hybrid model based on two eminent approaches namely, resource-reservation and extra offset-time based QoS that have already been investigated in the literature. We show that this model guarantees better performance with increase in number of traffic classes. We also simulate a complete topologically optical network bearing Poisson traffic to assess the performance of the proposed model as compared with the two aforementioned approaches
