Best answer 6 votes 6 votes Round-trip time (RTT) is the total time taken to send a signal and receive an acknowledgment of that signal. Refer: https://en.wikipedia.org/wiki/Round-trip_delay_time Transmission takes Tt time If a frame is transmitted then it takes Tp propagation time to reach receiver. Receiver can acknowledge only upon receiving frame now it again takes Tp time for the acknowledgement to reach the sender. Thus total Round Trip Time is Tt+Tp+Tp = Tt+2Tp It doesn't depend onwhether the link is Simplex or full duplex. It will be always 2*Propagation delay sh!va answered Sep 22, 2016 • selected Nov 8, 2017 by Soumya29 sh!va comment Share Follow See all 3 Comments See all 3 3 Comments reply thor commented Nov 29, 2016 reply Follow Share RTT =$ T_t + 2T_p$ or 2*Tp 0 votes 0 votes guptashekhar54 commented Oct 2, 2018 reply Follow Share Is there any change in efficiency of Go Back N protocol in full duplex or half duplex ? 0 votes 0 votes guptashekhar54 commented Oct 2, 2018 reply Follow Share Can we do piggybacking in half duplex? 0 votes 0 votes Please log in or register to add a comment.
