  1. this is not a very clear description of TCP windowing, as it contains flow control and it takes place earlier during 3-way handshake, there is lot of confusion in congestion window, windowing etc…please explain all in details for having a good and clear idea on it…start with entire TCP headers ,,,

  2. this video save my day. I have question. when the receiver send ACK 6 due dropped, does the receiver move the receiver window by one to ? (6 – 9) or retain to current receiver window (5 – 8) till 6 is received?
