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 = 100 Mbps.

The four links from the servers to the shared link have a transmission capacity of R_S = 50 Mbps.

Each of the four links from the shared middle link to a client has a transmission capacity of R_C = 60 Mbps per second.

SHOW CALCULATIONS

1. What is the maximum achievable end-end throughput (in Mbps) for each of four client-to-server pairs, assuming that the middle link is fair-shared?
2. Assuming that the senders are sending at the maximum rate possible.
   1. The link utilizations for the sender links (R_S) = %
   2. The link utilization for the client links (R_C) = %
   3. The link utilization for the middle link (R) = %
