Let's say Host A wishes to give Host B a sizable file. There are two routers, R1 and R2, and three connections, L1, L2, and L3, on the route from host A to host B. The links' various transmission rates are L1 = 500 kbps, L2 = 2 Mbps, and L3 = 1 Mbps. (Answer the following question while showing work) 1) What is the throughput for the file transfer, if there is no other network activity? 2) Let's say the file has a size of 4 Megabytes. How long will the file transfer from Host A to Host B take?
