2. 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 = 300 Mbps. The four links from the servers to the shared link have a transmission capacity of Rs = 50 Mbps. Each of the four links from the shared middle link to a client has a transmission capacity of Rc = 90 Mbps. ps 50 Mbps R-50 Mbps Rs 50 Mbps R-50 Mips R-300 Mbps Re90 Mbps Re90 Mbps Re90 Mbps Re90 Papa 2.a (2 pts.) What is the maximum achievable end-end throughput an integer value in Mbps) for each of four client- to-server pairs, assuming that the middle link is fairly shared (divides its transmission rate equally) and all servers are trying to send at their maximum rate? Please write the answer with brief explanation. 2.b (2 pts.) Assuming that the servers are all sending at their maximum rate possible, what are the link utilizations for the server links (with transmission capacity Rs)? Enter your answer in a decimal form of 1.00 (if the utilization is 1) or 0.xx (if the utilization is less than 1. rounded to the closest xx). Please write the answer with brief explanation. 2.c (2 pts.) Assuming that the servers are all sending at their maximum rate possible, what are the link utilizations of the client links (with transmission capacity Rc)? Enter your answer in a decimal form of 1.00 (if the utilization is 1) or 0.xx (if the utilization is less than 1. rounded to the closest xx). Please write the answer with brief explanation
