1.
When a XO resumes, does it send any notification via avahi, that it is
back? Because if it doesnt, then other XOs that have cleared it from
their lists, they will never search for it.</div></div></div></div></blockquote></div><div><br>I believe there is no "I am back" notification different than the normal way presence information is exchanged by the protocol.<br>
</div></div></blockquote><div><br>If not, then we have a problem. The other XOs will never know it is here, so they will never search for it. I think the "are u alive" request is destination specific.<br><br>I will do some sniffing and find out.<br>

<br>2. Every scans the network every 10min, to check whether its avahi
peers are alive, in multicast packets. Do these packets include the
address of the peers/targets? I think they do, unless i am very
confused. Couldn't we awake/resume the target XO when it receives these
specific packets? </div></div></div></div></blockquote></div><div><br>That's the point. Mdns is multicast and the XOs, when suspended, don't listen to multicast frames.<br> </div></div></blockquote><div>The suspended XO can be setup to wake up by multicast packets. This is technically possible afaik <br>
