Hello all,

Following our ROLL session at the IETF109 meeting, I had an action point to dig up pointers to prior discussions about DAO/DAO-ACKs in storing mode and the decision to go for a RootACK.

If you want only one pointer, that would be the video of the ROLL session at the IETF103 meeting https://youtu.be/7cwhMLaddqU?t=3408 , (start time 56:45, duration about 6 mn).

More pointers below
- discussions on ML about interpretation of DAO-ACK behaviour, e.g. as far back as 2015
  https://mailarchive.ietf.org/arch/msg/roll/8jf7B4O_SSz575fjv59EMH2xs7g/
- description of the issues in draft-ietf-roll-rpl-observations, Section 4, first published in Sept 2018
  https://tools.ietf.org/html/draft-ietf-roll-rpl-observations-04
- ROLL session at IET103 meeting (Nov 5, 2018, Bangkok)
  slides: https://datatracker.ietf.org/meeting/103/materials/slides-103-roll-roll-ietf103-v2-00.pdf
  minutes: https://datatracker.ietf.org/doc/minutes-103-roll/
  Excerpt “Pascal: we could specify a mechanism to get an ACK from the root all the
  way down the DODAG. Could be a new draft. ACTION: new draft on ACK from the root?”
- Video: (from time 56:45, about 6 mn) https://youtu.be/7cwhMLaddqU?t=3408
- ensuing draft https://datatracker.ietf.org/doc/draft-jadhav-roll-storing-rootack/ first published Apr 2020

Best regards

Dominique
