Problem 5 [15 pts]. Circuit switching vs packet switching a) Calculate how long it takes to send a 1Mb file over a 3Mbps link with a circuit switched network that uses 24 different frequency slots and requires a 600ms connection set up time. b) Assume you now have a 10 hop packet switched network, where each link is 3Mbps, and all packets are 1Kb. Neglect nodal processing, queueing and propagation delays
