About the closed() event, and reconnection strategy

Hello,

When directly connecting to an ICE server (no GLACIER2) from my node.js app (V3.6.2), I set ACM like this:

id.properties.setProperty('Ice.ACM.Close', '4');
id.properties.setProperty('Ice.ACM.Heartbeat', '3');
id.properties.setProperty('Ice.ACM.Timeout', '15');

proxy.ice_getCachedConnection().setCallback({
        closed() {
          debug('who called this closed() function???');
        },
});

It seems to me as the closed() function is actually called remotely by the ICE server.

If I disconnect the networking on my client, the closed() function is called only once I reconnect the networking again (which means that my client can connect to the server, detect that it has been closed by the server, and then invoke the closed() function.

I am correct?

if yes, my next question will be: should I try to detect a network failure, or should I just wait that my closed() function has been invoked to call again my reconnect() logic.

Many thanks for your answers !!
