Document: draft-ietf-dots-requirements-18 Reviewer: Robert Sparks Review Date: 2019-02-13 IETF LC End Date: 2018-11-23 IESG Telechat date: 2019-02-21 Summary: Ready, but with a process issue for the shepherd and AD to consider. This version addressed all of my comments on version -16. Thank you. However, the diff shows that a large number of SHOULDs were changed to MUSTs. I'm guessing that was in response to a comment in the TSVART review of -16. This large scale substitution makes me worry - are they really the right adjustments? Has the group reviewed and agreed to these normative changes? As a nit, I'll note that the additional description of heartbeating creeps into specifying protocol rather than requirements.
