When looking at the conversation in .pcap I can see "Calculated window size" is constantly growing with each packet. However there is no Window Update message is sent. Is this normal not to see it?

Thanks.

Can you claridy? "there is Window update message" - looks like you forgot the "no"? Otherwise the last sentence makes no sense.

Hi,

Yes I made a typo. "However there is no Window Update message is sent" is the correct one.

Okay, I updated the question.

"Window Update" only happens if the receiver ACKnowledges something that has already been acknowledged but the window size value has changed. So if you're seeing growing windows while new incoming data is acknowledged it's not a window update.
