Yeah, it could be due to high-loss from load (unfortunately).
You could try increasing the timeout value in discovery.py. If you
don't have dynamic link events, this should be able to survive temporary
timeouts.
What switches are you using?
In my program the discovery module times out links sometimes, causing
my program not working well. I will debug to find out details why the
link fails. Actually they are not supposed to fail. Maybe it's because
of huge data.

The goal is to detect link failures, so one would hope that would be the

I assume LLDP packets are sent periodically. If there is no LLDP, what
will be the most possible reason? The controller or the switch is too
busy?

It seems this module will periodically construct the topology. I dont
know why it will periodically time_out the links. I want to know in
what situations the links will time_out.
Thanks.
