In the image above, the sender of this packet is advertising a TCP Window of 63,792 bytes and is using a scaling factor of four. This means that that the true window size is 63,792 x 4 (255,168 bytes). Using scaling windows allows endpoints to advertise a window size of over 1GB. To use window scaling, both sides of the connection must advertise this capability in the handshake process.

If the sender does not receive an ACK for these packets within a specified amount of time, the sender will resend the two packets. On the sender side, the sender tries to make sure that at any given time he/she does not have in transit more bytes than the last received advertised window and therefore lower the probability of flooding the receiver. Sequence numbers allow receivers to discard duplicate packets and properly sequence out-of-order packets. Acknowledgments allow senders to determine when to retransmit lost packets. Reliability is achieved by the sender detecting lost data and retransmitting it. Retransmission timeout (RTO) and duplicate cumulative acknowledgements (DupAcks).

  • Sarah Bond is quoted in June 2021 stating Windows 11 comes “with superior graphics, amazing speed, and an incredible selection of games.” However, there are a few variables hanging on that statement.
