Quality of service is the ability to provide different priorities to different applications, users or dataflows, or to guarantee a certain level of performance to a dataflow. The paper uses timed Petri nets to model techniques that provide the quality of service in packet-switched networks and illustrates the behavior of developed models by performance characteristics of simple examples. These performance characteristics are obtained by discrete-event simulation of analyzed models.
