We want to compare the performance of a switch (L2) versus a router (L3) in terms of the average packet delay. In both, we use the same hardware that consists of a processor that runs at 1 Gbps (2 30 bps). The switch accepts 1 KB (2 10B) fixed size packets. The router accepts variable size packets with an average 1 KB. In both scenarios, packets arrive at a rate λ = 64 packets/s.
(a) What is the service rate (µ), in terms of packets/s, at each port for the switch and the router? 4 pts
(b) What is the traffic intensity (service utilization, rho) at each port for the switch and the router? 4 pts
(c) What is the average queuing delay for the switching port? 4 pts
(d) What is the average queuing delay for the router port? 4 pts
(e) Which one is faster and by how much?
