Problem 2:

Circuit Switching and Packet switching (20 pts) A circuit-switching scenario in which Ncs users, each requiring a bandwidth of 25 Mbps, must share a link of capacity 150 Mbps. A packet-switching scenario with Nps users sharing a 150 Mbps link, where each user again requires 25 Mbps when transmitting, but only needs to transmit 30 percent of the time.

When circuit switching is used, what is the maximum number of circuit-switched users that can be supported? Explain your answer. b. Suppose there are 11 packet-switching users (i.e., N-11). Can this many users be supported under circuit-switching? Explain
