And if it is written in the qeustion that "time required to sent window size of 36 KB" then in this case we have 2600 ms time, because in this case we are not worried about whether the data is recieved or not, they are just asking after what time you will send full window of 36 KB, so in that case answer should be 2600 ms, According to given question, there intention is second case, which is 2600 ms. 0 votes 0 votes rajoramanoj commented Oct 3, 2017 reply Follow Share @Shubhanshu i see many questions in which after what time you will send full window is mention but they consider last ack also . 0 votes 0 votes Shubhanshu commented Oct 3, 2017 reply Follow Share https://gateoverflow.in/1794/gate2014-1-27 In this @Bikram sir, said, both the answers are in the range in official key of gate. 1 votes 1 votes rajoramanoj commented Oct 3, 2017 reply Follow Share okiii.. thank u 0 votes 0 votes Please log in or register to add a comment.
