Best answer 4 votes 4 votes Question is wrong as well as the answer markeed by pooja ,.(i guess) time out at 32 KB (before timeout scenarioo should not be considered here) then after time out it will be like 4-8-16--20--24--28--32 6RTT 6*50=300ms 300ms should be correct answer Aboveallplayer answered Aug 21, 2016 • selected Aug 21, 2016 by papesh Aboveallplayer comment Share Follow See 1 comment See all 1 1 comment reply papesh commented Aug 21, 2016 reply Follow Share Yes correct... 1 votes 1 votes Please log in or register to add a comment.
