    4:18 *CORRECTION:* The sliding window does have significance. The erroneous bit is sent AFTER the sender window is empty. It sends the erroneous bit and continues where it left off. Meanwhile the receiver sends NACK of the erroneous bit with every ACK of subsequent bits.

    If frame 2 is lost, then receiver window should wait for frame 2, and then when timeout occurs on sender side, it will send frame 2 and then on receiving frame 2 on receiver side, receiver will acknowledge and will slide the window by 4 because 3,4,5 are already stored. On sender side on receiving acknowledge of 2, it will slide the window by 4. Is this correct?

    • @amaanmohammad1190
      @amaanmohammad1190 3 года назад +4

      If frame 2 is lost and frame 3,4,5 are received, the receiver window is not moved forward. The reciveer will simply put 3,4,5 in the buffer. When it receives frame 2 , it groups and delivers 2,3,4,5 and moves the window forward by 4 frames ( because a total of 4 frames were delivered).

    Do you know why the hell is my homework asking for the difference in window size between Selective Repeat and Go back N given the same number of bits for sequence number? I don't see why there would be any difference in the window size between the two.
