Compare GBN$,$ SR$,$ and TCP $($no delayed ACK$).$ Assume that the timeout values for allthree protocols are sufficiently long such that $5$ consecutive data segments and theircorresponding 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 $5$ datasegments to Host B$,$ and the $2$nd segment $($sent from A$)$ is lost. In the end, all $5$ datasegments 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 intotal? What are their sequence numbers? Answer this question for all three protocols.$($b$)$ If the timeout values for all three protocols are much longer than $5*$ RTT$,$ then whichprotocol successfully delivers all five data segments in shortest time interval?
