Transcribed Image Text:5-The four pairs share a common middle hop with a transmission capacity of R =
400 Mbps. The four links from the servers to the shared link have a transmission
capacity of Rs = 70 Mbps. Each of the four links from the shared middle link to a
client has a transmission capacity of Rc = 80 Mbps.
