Performance Analysis of Priority Queueing Systems Using Timed Petri Nets

The following article presents research results and performance analysis of Priority Queuing System (PQS) that are supporting the Quality of Service (QoS). Priority queuing models supporting three traffic classes (high, medium and low priority) in 5-3-1 architecture were designed and tested. The performance assessment of the tested system was carried out using temporal Petri nets. The use of simulation tools in the form of Petri Nets (PN) allowed for the evaluation and verification of waiting times, queuing mechanisms and traffic intensity using the queuing algorithm. It was shown that temporal models of Petri nets can be effectively used in modeling and analysis of the performance of priority queuing systems.
