Q2. 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=300Mbps. The four links from the servers to the shared link have a transmission capacity of RS=90Mbps. Each of the four links from the shared middl link to a client has a transmission capacity of RC=80Mbps. 1. What is the maximum achievable end-end throughput (in Mbps) for each of four client-toserver pairs, assuming that the middle link is fairly shared (divides its transmission rate equally)? 2. Which link is the bottleneck link? Format as Rc, Rs, or R 3. Assuming that the servers are sending at the maximum rate possible, what are the link utilizations for the server links (RsS) ? 4. Assuming that the servers are sending at the maximum rate possible, what are the link utilizations for the client links (RC) ? 5. Assuming that the servers are sending at the maximum rate possible, what is the link utilizations for the shared link (R)
