The following figure shows a TCP transaction. Assume Host A always has data to send, and each packet has size 40 Bytes. Assume Host A has a send window of 80 Bytes, that is, it can send two “in-flight” packets maximum. Answer the following questions. Notes: Pipelining using Go-Back-N  At the time marked “1”, i.e., when the first packet times out, will Host A send any packet? if your answer is no, explain why not; if your answer is yes, how many packets will be sent, what are the sequence numbers of them?  At the time marked “2”, i.e., when the ACK of the 2nd packet is received by Host A, will Host A send any packet? if your answer is no, explain why not; if your answer is yes, how many packets will be sent, what are the sequence numbers of them?

Based on the following facts, calculate the four types of delays discussed in class. If any type of delay cannot be determined, clearly state so in your answer and give the reason why. Host A sends 3000 Bytes in one packet to Host B. There is one router between the two hosts. The distance between each host and the router is both 5 Km, and the rate on both links are 10 Mbps. Assume an ideal router that does not cost any time to move bits from the incoming port to the outgoing port, however, the router will “store and forward” each packet.

Facebook is a monopolist. Assume that their marginal cost curve shifts up, but that their demand curve remains the same and that Facebook does not shut down. Compared to before the increase in Facebook’s marginal cost, Facebook will ______ its price and ______ its level of production.
