[20pt] Compare GBN, SR, and TCP (no 500ms delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 8 consecutive data segments (Seq. no. 1 to 8)
and their corresponding ACKs can be received (if not lost in the channel) by the receiving host
(Host B) and the sending host (Host A) respectively.
Suppose Host A sends 8 data segments to Host B, and all segments except the 1st and last (8th)
are lost. In the end, all 8 data segments have been correctly received by Host B.
a. How many segments has Host A sent in total? What are their sequence numbers?
Answer this question for all three protocols.
b. How many ACKs has Host B sent in total? What are their sequence numbers? Answer this
question for all three protocols.
