Performance: Maximum end$-$end throughput. Consider the scenario shown below, with two clients sending to a server. The links attached to clients each have a capacity of $R_1=R_2=100Mbps.$ The link from the router to the server has a capacity of and $R_3=10Mbps,$ which is shared evenly between the two sources when they are each sending at their maximum rate.

What is the maximum achievable end$-$end throughput $($in Mbps$,$ give an integer value$)$ for each client$-$to$-$server pair, assuming that the client is trying to send at its maximum rate?
