Multiclass Multiserver Service Differentiation in Optical Flow Switched Networks

Abstract

In this paper we wish to analyze the scheduling policy of Optical Flow Switching (OFS) network w.r.t the multiclass priority queue. OFS is an exciting new switching technique which can transfer Terabytes of data in a fraction of seconds, The exquisiteness of OFS is that no buffering and processing is involved at any intermediate routes. Using priority queuing, the flow w.r.t multiclass for multiserver QoS is implemented. We develop the Multiclass priority model with non-pre-emptive model (with no forced termination) to evaluate the performance of the Multiclass Multiserver supported OFS network using the multiclass priority queue. This work presents an entirely new dimension to the Queuing at Access Nodes. Extensive results obtained show the significant change in total and average waiting time as the number of servers is increased. On the other hand, as the priority of the class decreases, the average waiting time also increases.
