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=10 Mbps, R2=500 kbps, and R3=750 Kbps. (1Kbit=210bit)
a) Assuming no other traffic in the network, what is the throughput for the file transfer?
b) Suppose the file is 12 million bytes. Roughly, how long will it take to transfer the file to Host B?
