Suppose Host A wants to send a large file to Host B. The path from Host A to Host B has three link, of rate 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 will it take to transfer the to Host B?
c. repeat (a) and (b), but now with R2 reduced to 100 kbps.
