Congestion Window Size The congestion window size for this connection. Congestion window size is the maximum amount of data that is sent without waiting for an acknowledgment from the remote socket. The value that is used when congestion is detected in the network to limit the amount of data that is sent by the local stack. A valid value is an integer.

Connection Duration The amount of time, in seconds, since this connection was created. This value is displayed as a time value (for example, 22.0000s or 4m 20s). A valid value is an integer.
