Question 1 A number of users share a 4Mbps link at the edge of a network. Each user requires 100 Kbps when transmitting, but each user transmits only 10 percent of the time. What are the average and peak (max) rates of each user? How many users can this link support if we use circuit switching? An ISP allows a number of users to share this link based on the average rate. How many users will the ISP allow in this case? Is it sustainable? Let us suppose we use packet switching to multiplex users at this link. Will there be any queuing delay if two or fewer users transmit at the same time? Will there be any queuing delay if twenty users transmit at the same time? Reason. (CSc 567) Given that there are 20 active users accessing this link, what is the chance (probability) that 2 or more are transmitting at the same time? a. b. c. d. e
