Suppose we have a circuit-switching scenario in which Ncs users, each requiring a bandwidth of 10 Mbps, must share a link of capacity 200 Mbps and a packet-switching scenario with Nps 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. CS circuit-switched users 200 Mbps link packet-svitched 200 Mbps link 4) When circuit switching is used, what is the maximum number users of circuit-switched users that can be supported and why
