Suppose two Hosts, A and B, are separated by 100 meters, and are connected by a direct link of R = 10 bps. Suppose the propagation speed over the link is 200 meters/sec. Consider sending a file of 1,000 bits from Host A to Host B, and no other traffic in the network. Suppose that the file is sent as one big message. Calculate the transmission delay and the propagation delay. How long does it take to receive the file? Assume there is one router between Hosts A and B with both links at 10 bps transmission rate. Assume that the router uses store-and-forward packet switching. What is the end-to-end delay to send the file as one big message? Assume that the file is broken up into 10 packets with each packet containing 100 bits, and each packet is acknowledged by host B and the transmission time of an acknowledgment packet is negligible. Finally, assume that the sender cannot send a packet until the preceding one is acknowledged. How long does it take to receive the file on Host B? Must show necessary intermediate steps and final answers for full credit.
