Consider the throughput example. Now suppose that there are 4 client-server pairs. Denote R_s1
^,R_s2, R_s3
,R_s4 ,R_{c1 ,}R_{c2 ,}R_c3,R_c4
and R for the rates of the server links, client links, and network link. Assume all other links have abundant capacity and that there is no other traffic in the network besides the traffic generated by the 4 client-server pairs.

Question: Assume that for i = {1,2,3,4}, R_si = R_ci = R , assume that all routers have infinite buffer
capacity, meaning that packets are never dropped and are eventually forwarded by a router. What
is the throughput for the Client Server pair 1? What is the throughput for Client Server pair 3?
