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.

How does the sliding window slide when frame 2 is not acknowledged? and Why the sender won't send a new packet when frame 3 is acknowledged but wait for frame 4 to be acknowledged to send frame 6? Thank you.

Dude, but it has sent for 3, and not for 2. So, as per the sequence num, it sends nack for 2, and the others are normal

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 3 жыл бұрын

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.

Assume that two computers A and B are connected with 512 Gbps bandwidth. Consider if the distance between the hosts is M metres and the link speed of the medium is 2 x 109 m/s. If Computer A need to send a one- kilobyte packet to Computer B. What is the minimum distance M required such that the propagation delay equals the transmission delay?
