Suppose users share a 1-Gbps link. Also, suppose each user requires 200 Mbps when transmitting, but each user only transmits 30 percent of the time. a. (5 pts.) When circuit switching is used, how many users can be supported?

b. (5 pts.) For the remainder of this problem, suppose packet switching is used. What is the maximum number of users that can be supported if the required blocking probability is strictly less than 0.05 and what is the blocking probability with the determined maximum number of users?
