I guess that is given in CN textbook- I forgot the exact reason but is surely mentioned in book. 1 votes 1 votes bobo diarda commented Feb 24, 2016 reply Follow Share i think theoretically also it is NO as we would need a much larger ethernet frame length to detect collision.As the ethernet frame is of limited or fixed length,we cannot send the frame over large distances and still detect collision(but in practical cases the limit is set by the electrical interfaces and attennuation of the signal). 0 votes 0 votes Anurag_s commented Feb 24, 2016 reply Follow Share maybe due to frame size for csma/cd, tt>=2*prop time if distance is too much, frame size ll increase , it 'll increase than 1500 and after that size , if we allow may lead to monopolisation of the channel. 1 votes 1 votes Sushant Gokhale commented Nov 16, 2016 i edited by Sushant Gokhale Nov 16, 2016 reply Follow Share I think no because of limitation on length of cables that can be used in LAN 0 votes 0 votes Please log in or register to add a comment.
