Consider the scenario shown below, with four different servers connected to four different clients over four three-hop paths. The four pairs share a common middle hop with a transmission capacity of R = 200 Mbps. The four links from the servers to the shared link have a transmission capacity of RS = 90 Mbps. Each of the four links from the shared middle link to a client has a transmission capacity of RC = 10 Mbps. You might want to review Figure 1.20 in the text before answering the following questions • What is the maximum achievable end-end throughput (in Mbps) for each of four client-to-server pairs, assuming that the middle link is shared (divides its transmission rate equally)? • Which link is the bottleneck link? Format as Rc, Rs, or R • Assuming that the servers are sending at the maximum rate possible, what are the link utilizations for the server links (RS)? Answer as a decimal • Assuming that the servers are sending at the maximum rate possible, what are the link utilizations for the client links (RC)? Answer as a decimal • Assuming that the servers are sending at the maximum rate possible, what is the link utilizations for the shared link (R)? Answer as a decimal
