Thank you, helped a lot to understand it!

TCP is suppose to work on a byte stream. And the Advertised window is based on Bytes. So how come we are having fixed PACKET sized window ? is it that the window size (in bytes) is divided by the Maximum segment size of one packet to get total number of packets that can be used ? If this is so then Advertised window changes with the current buffer capacity at the receiver. Does that mean on ever ACK advertising the window size, this # of packets in the current window might change ??

I dont say You lost n-th packet. I say that you can lost a ack-packet. If sender receive a next ack before timeout, He understand that packet is arrived and ack is in later or died.

@cybercrasher2 Not true, you may loose the n-th packet only, Also receiving ack for n+1 (and no ACK for "n") does not mean that "n' was lost - it might have been routed through a slower route and thus - just delayed

[Ghennas]

This video is really useful! How did you make it? I mean which software has been used to simulate the protocol?

[cybercrasher2]

And if you lost "ACK n", when receive ACK n+1 ( if timeout don't expired) the sender understand that "Packet n" is arrived.

This happen because ACK is cumulative in GO-BACK-N
