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 RI =500 kbps, R2 =2 Mbps, and R) = I 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 through put, roughly how long will it take to transfer the file to Host B?
c. Repeat (a) and (b), but now with R2 reduced to 100 kbps.
