Abstract


In this paper we propose and analyze performance of a utilization-driven QoS-enhanced intelligent stochastic fair packet scheduler for IP traffic in a smart router with timing jitter analysis. The unique advantages of the proposed scheduler are: the scheduler offers the benefit of arbitrarily pre-programming the process utilization ratio; it solves the problem of starvation for low priority processes; it solves the major bottleneck of the benchmark scheduler Earliest Deadline First’s (EDF) failure at heavy loads. We consider three classes of multimedia IP traffic: VoIP, IPTV and HTTP. We analyse the performance of the scheduler addressing important QoS parameters, scheduling jitter, the scheduler’s noise response, packet loss rate and mean waiting time. Simulation results show that the proposed scheduler has a performance improvement compared to current state-of-the-art schedulers.
