d] In a TCPI'IP network, suppose Host A wants to send a large file of size :1 million bytes, to Host B. The path from Host A to Host B has three Links, of rates R1 = 5012} khps, R2 = 2 Mbps, and R321 Mhps. i] Dividing the file size by the throughput, roughly how long it takes transfer the file to oat E? ii) Now assuming no other traffic in the network, what is the throughput for the file trans fer
