Problem 2 (24 points) A circuit-switching scenario in which No users, each requiring a bandwidth of 20 Mbps, must share a link of capacity 200 Mbps. A packet-switching scenario with Nos users sharing a 200 Mbps link, where each user again requires 20 Mbps when transmiting, but only needs to transmit 10 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 For the remainder of this problem, suppose packet switching is used. Suppose there are 15 packet-switching users (.e., Non 15). Can this many users be supported under circuit- b) switching? Explain. c) What is the probability that a given (specific) user is transmitting, and the remaining users are not transmitting? What is the probability that one user (any one among the 15 users) is transmitting, and the remaining users are not transmitting? When one user is transmiting, what fraction of the link d) e) 0 What is the probability that more than 8 users are transmitting? Comment on what this implies capacity will be used by this user? What is the probability that any 8 users (of the total 15 users) are transmitting and the remaining users are not transmitting? (Hint: you will need to use the binomial distribution). about the number of users supportable under circuit switching and packet switching
