Suppose Host A wants to send a large file to Host B. The path from Host A to
Host B has three links, of rates R1 = 500 kbps, R2 = 2 Mbps, and R3 = 1 Mbps.
a. Assuming no other traffic in the network, what is the throughput for the
file transfer?
b. Suppose the file is 4 million bytes. Dividing the file size by the throughput,
roughly how long will it take to transfer the file to Host B?
