a) What is the maximum achievable end-end throughput (in Mbps) for each of the four client-to-server pairs, assuming that the middle link is fair-shared (i.e., divides its transmission rate equally among the four pairs)? Link 1 =? Mbps ; Link 2 =? Mbps; Link 3 =? Mbps; Link 4 =? Mbps ; b)Which link is the bottleneck link for each session? a. Sender link (RS) ; b. Client link (RC); c.Middle link (R)? c) Assuming that the senders are sending at the maximum rate possible, what are the link utilizations for the sender links (R_S), client links (R_C), and the middle link (R)? Sender links (R_S) = ? %. Client links (R_C) = ? %. Middle link (R) = ? %.

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=100Mbps. The four links from the servers to the shared link have a transmission capacity of RS=30Mbps. Each of the four links from the shared middle link to a client has a transmission capacity of RC=80Mbps per second
