Hello to all,

We've had a productive IETF, and therefore we've got a lot of work to do.
My understanding of the current situation.


1. draft-ietf-babel-rfc6126bis

This has been in last call, like, forever.  We're still waiting for IESG
review, let's please make it happen.  Donald, Russ, could you please poke
the responsible AD?

(I'm still not happy about Unicast Hellos, but I understand I'm in the
minority, so I'll shut up.  Er, no, I'll keep complaining loudly, but
I won't block the process.)


2. draft-ietf-babel-source-specific

This is ready for standardisation.  Joel Halpern has reviewed -02 and -03,
and the -03 review was positive.  Last call, please?


3. draft-ovsienko-babel-rfc7298bis

Denis has produced a -00.  I believe that Toke is interested both in
reviewing the draft and implementing it, and so am I.  The subject of
adoption was raised at the meeting, and nobody objected.  So:

  3.1 is anyone opposed to adopting this draft?
  3.2 Denis, do you want to produce a new revision before adoption, or are
      we welcome to adopt?
  3.3 Toke, do you want to review before adoption, or are we welcome to adopt?

I am in favour of adopting straight away.


4. Babel over DTLS

Three points of contention:

  4.1 does DTLS go over the Babel port, or do we request a different port
      for Babel over DTLS?
  4.2 is the client port equal to the server port, or do we use ephemeral
      ports on the client side?
  4.3 do we leave Hello/IHU unprotected, or do we send Hello/IHU over
      unicast and do something smart for link quality estimation?

I think that Antonin and David should get in touch, and produce
a compromise draft that it not necessarily consensual (perhaps with all
reasonable choices outlined).  Once we have a draft, we can ask for
adoption, and work out the details at the working group level.


5. draft-ietf-babel-information-model

Barbara's working copy (post -01) makes a lot of sense to me.  I suggest
she should submit -02 with the changes we discussed, and have it reviewed
by Toke, David, and hopefully Markus.  Since Toke's implementation is the
most complete, his input is likely to be the most useful (and critical).

My wishes for a safe return home, and kisses on both cheeks to all of you,

-- Juliusz
