Best answer 5 votes 5 votes In general, after the cth failed attempt, resend the frame after k · 51.2μs, where k is a random integer between 0 and 2c − 1 so here max waiting time occurs when we choose the value of k max between 0 to 2^4 - 1 = 15 so we choose value of k =15. now waiting time = 15 *51.2 μs = 768 μs ref: https://en.wikipedia.org/wiki/Exponential_backoff resuscitate answered Jan 5, 2016 • selected Jan 5, 2016 by Pooja Palod resuscitate comment Share Follow See all 2 Comments See all 2 2 Comments reply akankshadewangan24 commented Sep 20, 2017 reply Follow Share What's the actual ans ????,, 0 votes 0 votes saxena0612 commented Sep 20, 2017 reply Follow Share Its a general question where slot time is not given thus we took 51.2us because of standard ethernet slot time. Thus the answer is correct for general case but in practical the slot time would be given in the question itself. 0 votes 0 votes Please log in or register to add a comment.
