3. Calculating throughput. Given the adjacent diagram illustrating client server pairs with Rs,Rc, and R are the rates for the server links, client links and network link. Assume all other links have abundant capacity and there is no other traffic in the network besides the traffic generated by M client-server pairs. a. If Rs is 35Mbps and RC is 25Mbps,R is 120Mbps, and there are 5 concurrent users (i.e., M=5 ), what is the maximum throughput from client to server? Explain your answer. b. If RS is 15Mbps and RC is 25Mbps and R is 100Mbps, what is the minimum value for M to make the bottleneck occur at R instead of either RS or RC ? Round M up to the nearest integer. Explain your answer. c. If Rs is 16Mbps and Rc is 12Mbps and R is 28Mbps, what is the minimum value for M to make the bottleneck occur at R instead of either RS or RC ? Round M up to the nearest integer. Explain your
