Homework # 1 Due Date: 18th Feb 2018 (11:59pm) Marks: / 50 Q1: Consider the two scenarios below: A circuit-switching scenario in which Ncs users, each requiring a bandwidth of 25 Mbps, must share a link of capacity 200 Mbps. A packet-switching scenario with Nps users sharing a 200 Mbps link, where each user again requires 25 Mbps when transmitting, but only needs to transmit 30 percent of the time. circuit-swit 200 Mbps users N. packet Witched 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. (5 marks) b. Suppose packet switching is used. Suppose there are 15 packet-switching users (i.e., Ns-15) Can this many users be supported under circuit-switching? Explain (5marks) c. What is the probability that a given (specific) user is transmitting, and the remaining users are not transmitting? (5marks)
