Re: [6tisch] 6P and Sf0 issue: 6top protocol behaviour at boot

Correct Diego

And that's a desired effect so that a node gets a lot of bandwidth to complete 
its join. You better complete a few at a time then have hundreds half way 
through and none fully done.

We may actually reject a join if the queue is too long, exhausting=sleep well 
and come back in 10

Take care,

Pascal

Pascal,
  I was thinking of a worst-case condition: all neighbours are
willing to join. A limited pool would satisfy only a part of them, thus
putting the rest of the nodes in a join queue. Am I correct?

Hello Diego:

One suggestion would be that when a node attempts to join, the parent 
immediately grants a set of cells for the join process from a limited pool (to 
avoid DDOS). These cells are to be released at the end of the join and are 
there to boost the bandwidth for that critical phase.

Cheers,

Pascal

Subject: [6tisch] 6P and Sf0 issue: 6top protocol behaviour at boot

Dear all,
Although it was discussed, there is no specification
on the 6top behaviour at boot. The discussion point here is if the
6top messages shall be transmitted on minimal cells until
the slotframe 1 (SFR1) has been populated enough to support
the transactions.
  - The use of minimal is optional. In case minimal is used,
the decision on when to switch is out of scope?
  - In case minimal is not used, shall we specify another
mechanism to enable 6top to transmit messages?
Thanks!
Regards,
 Diego Dujovne
