TCP::snd_cwnd

Description

Returns the TCP congestion window (cwnd), the maximum unacknowledged data the connection can send due to the congestion control algorithm.
The actual amount of outstanding data may be lower, due to lack of application data to send, the remote host’s advertised receive window, or the size of the BIG-IP send buffer.

Syntax

The cwnd in bytes.
