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=500kbps, R2=2Mbps, and R3=1Mbps.
a. Assuming no other traffic in the network, what is the throughput for the file transfer.
b. Suppose the file is 4 million bytes. Roughly, how long will it take to transfer the file to Host B?
c. Repeat (a) and (b), but now with R2 reduced to 100kbps.
