Compare gbn, sr, and tcp (no delayed ack). assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding acks can be
received (if not lost in the channel) by the receiving host (b) and the sending host (a) respectively. suppose host a sends 5 data segments to host b, and the second segment (sent from a) is lost. in the end, all 5 data segments have been correctly received by host b.
(a) how many segments has host a sent in total and how many acks has host b sent in total? what are their sequence number? answer this question for all three protocols.
(b) if the timeout values for all three protocols are much longer than 5 rtt, then which protocol
successfully delivers all five data segments in the shortest time interval?
