1. 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 = 200kbps, R2 =4Mbps and R3=10Mbps.

1. Assume 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.
