Priority queuing of long-range dependent traffic
Mohamed Ashour, Tho Le‐Ngoc · 2004
By using multiscale wavelet models (MWM), the multi-scale queuing (MSQ) technique is extended to evaluate the queue length distribution for two DiffServ classes fed with long-range dependent (LRD) traffic. The higher-priority class is first served by using an MWM/D/1 queue to estimate the unused capacity that is subsequently characterized by a MWM model in the analysis of the queue length distribution of the lower-priority MWM/MWM/1 queue. Comparison with simulation results shows that the proposed analytical technique can provide a tight bound on the queue length distribution.
