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 $=100$ Mbps$.$ The four links from the servers to the

shared link have a transmission capacity of RS $=10$ Mbps$.$ Each of the four links from

the shared middle link to a client has a transmission capacity of RC $=30$ Mbps$.$
