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.

Answer the following questions:

a. 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., Nps = 11). Can this many users be supported under circuit-switching? Explain
