5-The four pairs share a common middle hop with a transmission capacity of R = 400 Mbps. The four links from the servers to the shared link have a transmission capacity of Rs 70 Mbps. Each of the four links from the shared middle link to a client has a transmission capacity of Rc= 80 Mbps. Y A. What is the maximum achievable end-end throughput (in Mbps) for each of four client-to-server pairs, assuming that the middle link is fairly shared (divides its transmission rate equally)? B. Which link is the bottleneck link? Format as Rc, Rs, or R?
