Similar question here.

Basically it is not something that you will see as a value in a packet capture.

If you have Linux on the sending host you can do the following:

  • check the available and used congestion algorithm with "sysctl -a | grep congestion"
  • see the cwnd of all the established connections with "ss -ti"
  • see the cwnd for the last connections with "ip route show cache"
