Priority Based Wavelength Routed WDM Networks: A Queueing Theory Approach

Full text: PDF

Abstract

The present paper proposes a new model for priority assignment to the incoming call connection request for all optical WDM communication, adopting standard queuing theory concept. The model has been proposed for three different levels of call connection priorities, categorizing them into three types of signals as type0, type1 and type2 according to increasing priority, and generation probabilities of P0, P1 and P2 respectively. The traffic at the node will be serviced according to the priority leveled on the header of the assigned packets. A traffic throughput model has been developed to evaluate the blocking probability of three types of connection requests.
