Assignment 3: Q1. Consider the two scenarios below: A circuit-switching scenario in which Nes users, each requiring a bandwidth of 10 Mbps, must share a link of capacity 100 Mbps. A packet-switching scenario with Nps users sharing a 100 Mbps link, where each user again requires 10 Mbps when transmitting, but only needs to transmit 20 percent of the time. Round your answer to two decimals after leading zeros. 1. When circuit switching is used, what is the maximum number of users that can be supported? 2. Suppose packet switching is used. If there are 19 packet-switching users, can this many user be supported under circuit-switching? Yes or No w/ explanation. 3. Suppose packet switching is used. What is the probability that a given (specific) user is transmitting, and the remaining users are not transmitting? 4. Suppose packet switching is used. What is the probability that one user (any one among the 19 users) is transmitting, and the remaining users are not transmitting? 5. When one user is transmitting, what fraction of the link capacity will be used by this user? Write your answer as a decimal.
