See 5th packet is lost so we retransmitted 5th packet, after that 9th packet is lost so it is retransmitted. In GBN whenever every 5th packet is lost then the outstanding packet at that particular time are retransmitted again. 0 votes 0 votes rajoramanoj commented Oct 3, 2017 reply Follow Share is it not like that in GBN 1 2 3 4 5 6 5 6 7 8 9 10 8 9 10 10 in SR 1 2 3 4 5 6 5 7 8 9 10 9 0 votes 0 votes Please log in or register to add a comment.
