Assume that the timeout values for GBN, SR, and TCP protocols are sufficiently long such that 6 consecutive data segments (assume the payload is 1 byte) can be received (if not lost in the channel) by the receiving host (Host B) and their corresponding ACKs can received by the sending host (Host A). Suppose Host A sends 6 data segments to Host B, and the 4th segment (sent from A) is lost. In the end, all 6 data segments have been correctly received by Host B. For GBN, SR, and TCP (no delayed ACK and no fast retransmit) protocols how many segments has Host A sent in total and how many ACKs has Host B sent in total? What are their sequence numbers? Assume the sequence numbers start from 1.
