Compare GBN, SR and TCP (no delayed ACK)
Compare GBN, SR and TCP (no delayed ACK). Assume that timeout values for these protocols are sufficiently large such that 6 consecutive data segments and their corresponding ACKs can be received by the receiving Host B and the sending Host A, respectively. Suppose Host A sends 6 data segments to Host B, and the 3rd segment (sent from A) is lost. In the end, all 6 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 numbers?
b. If the timeout values for all three protocols are much longer than 6 RTT, then which protocol successfully delivers all six data segments in shortest time interval and why?
