NX will do a "Handshake" with the license server in "some regular intervals". The handshakes are called heartbeats.
The time between these heartbeats is not published to make hacking more difficult.
I.e NX : "ok continue using license x ?"
License server : "yes."
If these heartbeats aren't responded, NX will stop working after a few lost heartbeats. ( maybe 5-10 minutes)
if the network traffic is lost but later reconnected, NX will/should reconnect to the license without issues.

Tomas
