Extracted text: Link Utilization. Consider the scenario below where 4 TCP senders are connected to 4 receivers. The servers transmit to the receiving hosts at the fastest rate possible (i.e., at the rate at which the bottleneck link between a server and its destination is operating at 100% utilization, and is fairly shared among the connections passing through that link). Server-3 Server-2 Server-4 Server-1 Rs Rs Rs Rs RC Rc RC RC Host-4 Host-3 Host-1 Host-2 Suppose that R =1 Gbps and Rc is 300 Mbps and Rs is 200 Mbps. Assuming that the servers are sending at their maximum rate possible, enter the link utilization of the shared link, whose rate is R below. Enter your answer as a decimal, of the form 1.00 (if the utilization is 1, or 0.xx if the utilization is less than 1, rounded to the closest xx). The utilization of the shared central link, whose rate is R, is: [A]
