Measurement based analysis of delay in priority queuing
2001
The priority queueing mechanism is analysed to verify its effectiveness when applied for the support of expedited forwarding-based services in the differentiated services environment. An experimental measurement-based methodology is adopted to outline its properties and end-to-end performance when supported in real transmission devices. A test layout has been set up over a metropolitan area for the estimation of the one-way delay. The effect of the buffering architecture and of the background traffic have been evaluated, moreover a worst case analysis of the average one-way-delay that validates the experimental results is proposed.
