Modeling Traffic Shaping and Traffic Policing in Packet-Switched Networks

Traffic shaping is a computer network traffic management technique which delays some packets to make the traffic compliant with the desired traffic profile. Traffic policing is the process of monitoring network traffic for compliance with a traffic contract and dropping the excess traffic. Both traffic shaping and policing use two popular methods, known as leaky bucket and token bucket. The paper proposes timed Petri net models of both methods and uses these models to show the effects of traffic shaping and policing on the performance of very simple networks.
