Consider a router shown in the below figure. It serves 4 users, and its outgoing link capacity is 200 Mbps. The ith user has p; probability for being active. When active, the user generates data at 100 Mbps. Suppose that p = 0.3, p2 = 0.5, p = 0.2, and p = 0.4. What is the probability of the router being congested? Please provide your calculation details. 100 Mbps 100 Mbps 100 Mbps 100 Mbps 4 users 200 Mbps link
