can I think that these events(EventOFPXXX, EventNetworkXXX) are RYU’s
built-in events? Yes.
and we can *only* define(and send) our own events during the handling of
these build-in events? No. You can define your own event and send it
whenever you want. For exemple, you can use ryu events, or the constructor
method or the start() method to trigger your event.
Cheers.
