KeepAlive KeepAlive on TCP level is a feature intended to verify the availability and
functioning of the communication partner (client) and to maintain a TCP net-
work link if the network is inactive.
The server sends KeepAlive messages (TCP packets without data) to the
client in regular intervals (KeepAlive time) while the network is inactive, and
the client responds to these messages.
If the client does not respond to a KeepAlive message, the server assumes
that the link is down or the client is inactive and closes the TCP link.

LSB Least Significant Bit
