(Solved) : 3 Tcp Gbn Sr 20 Points Compare Gbn Sr Tcp Delayed Ack Assume Timeout Values Three Protoco Q30269883 . . .
Need help with GBN, ST, and TCP if someone could help as soon aspossible
3. TCP, GBN, and SR (20 points) Compare GBN, SR, and TCP (no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 4 consecutive data segments with sequence number 1, 2, 3, 4 can be received by the receiving host (Host B) and their corresponding ACKs can be received by the sending host (Host A). Suppose Host A sends data segments to Host B, and the first ACK (sent from Host B to Host A) is lost. In the end, all the 4 data segments have been correctly received by Host B. (no proof is required) a) If GBN is applied, how many data segments has Host A sent in total, and what are their sequence numbers respectively? How many ACKs has Host A received in total, and what are their sequence numbers respectively? (8 points) Answer b) IfSR is applied, how many segments has Host A sent in total, and what are their sequence numbers respectively? How many ACKs has Host B sent in total, and what are their sequence numbers respectively? (6 points) Answer c) If TCP is applied, how many segments has Host A sent in total, and what are their sequence numbers respectively? How many ACKs has Host A received in total, and what are their sequence numbers respectively? (6 points) Answer Show transcribed image text
