Abstract :
Engineering an enterprise to efficiently support integrated voice and data services requires sophisticated queuing disciplines to meet quality of service requirements. This study evaluates tradeoffs with three queuing schemes. Knowing that the choice of queuing discipline affects utilization, we ran a simulation for each of three queuing schemes - first come, first served (FCFS); priority queuing (PQ); and class-based weighted fair queuing (CBWFQ) - evaluating utilization at various bandwidths that would meet QoS requirements. The results showed that, with these three queuing disciplines, voice and data packets can receive the desired QoS.
