TCP Slow start threshold

0

Is it possible to capture TCP slow-start threshold (ssthresh) in Wireshark? If yes, is there a custom field (column) for it on Wireshark?

It, like the congestion window, is not a field in a TCP packet, so it can't be directly captured. They're internal state values maintained by the TCP stack on a host.

About the most that could be done would be to guess the value based on the TCP traffic. Wireshark currently doesn't do that; I don't know whether anybody's developed code to do that.
