Suppose we have a circuit-switching scenario in which N users, each requiring a bandwidth of 10 Mbps, must share a link of capacity 200 Mbps and a packet-switching scenario with N users sharing a 200 Mbps link, where each user again requires 10 Mbps when transmitting, but only needs to transmit 10 percent of the time; each illustrated to the right. 4) When circuit switching is used, what is the maximum number of circuit-switched users that can be supported and why? Nes 200 Mbps link circuit-switched users Nos packet-switched users 200 Mbps link 5) Suppose there are 39 packet-switching users (ie., N=39). Can this many users be supported under circuit-switching (why or why not)? 6) In the packet switching scenario, with N = 39, what is the probability that more than 20 users are transmitting?
