Hello, all!

I have some doubts:

Let's suppose i have a CTP network made out of 2 nodes only (this is a test
I ran), the sink and a "standard". Now let's assume that I step apart these
two nodes for as far as they're barely "visible" to each other (I found this
to be around 60 meters).
Faced whith this situation, I observed several packages being re-sent by the
"standard" node into the sink, never failing the order (i analysed the
sequence number), and i presume this to be caused by the ACKs that never got
back, thus causing the re-sending.
Stepping them a little bit farther apart, i started noticing some gaps in
the sequence number, as if some packets were totally lost.
I also noticed that if I stay at 60 meters and have relatively fair
transmission, going to 80 and getting back to 60 doesnt always provide same
delivery rates (sometimes i didnt get anything when going back to 60, even
though i received something before).

So my questions are:
- How many attempts does it take for a packet to be discarded from
retransmission, after many attempts without getting ACKs back? TEP 123 says
they're placed in a queue for future retransmission, but I presume they
don't stay there forever? Or else I wouldnt notice sequence number gaps in
the received packages...? Does the CTP tree breaks here and starts looking
for a new path?
- If the link gets weak enough, does the "standard" node re-attempt to
recreate a CTP tree and discards all queued messages? How weak (or
strong) needs a link to be for the nodes to establish a route? I ask
this because the apart/together thing, where it seems the tree wasnt
being "rebuilt" when it was perfectly healthy minutes before in the
same position (with the several retransmission to assure packet
delivery).

Thank you for your help!

Pedro
