tcp window recive incresing size during three way handshak

Post by brahim48 »

I have a question regarding TCP receive window size Here is a example from the application Wireshark:

client A :syn, win=8192 , ws=4 ====>
<===== client B: syn, ack win 5840 , ws=128
client A : Ack win=65700 ,

How did we obtain 65700(increasing from 8192 to 65700) in three way handshake ? and how dose the ws negotiated?

Thank you in advance
