Queuing model of dropping flow control. Derive the queuing model given in Exercise 2.9. Assume packets are dropped halfway through the network on average and are immediately reinjected into an input queue.
Exercise 2.9
Simulation. Write a simple computer program to simulate our example network. Using this program, experimentally determine the network’s latency as a function of offered traffic. How do your results compare to the analytical results from Equation 2.3 and Figure 2.11? Also compare against the relative delay given by the queueing model
where T0is the zero-load latency — the latency of a packet that is never dropped by the network.
