Typically, TCP Keepalives are sent every 45 or 60 seconds on an idle TCP connection, and the connection is dropped after 3 sequential ACKs are missed. This varies by host, e.g. by default, Windows PCs send the first TCP Keepalive packet after 7200000ms (2 hours), then send 5 Keepalives at 1000ms intervals, dropping the connection if there is no ...
