Re: Communication in response to the OIF



stephen,

just a minor hint, not only "running code":

- but "interoperability" and "backward/forward compatibility"
  i'm closing the loop here with the mail from fred either it
  is 100% interoperable and compatible or it is not ospf (or
  is-is or something else), there is no graduation here (i.e
  i don't think there in any value in saying "oif has endorsed
  gmpls concepts with differing ospf protocol details")

- and in the "right way" reason why i'm asking protocol
  specific reviews by the corresponding working groups,

both are the guarantees that an SDO gives to both vendors
and operators is succeeding in their developments on a
long term basis.

Dimitri, the point I was trying to make was that it should not alarm CCAMP
that the OIF has a relationship with the ITU-T.  On the matter of not having
work reviewed by CCAMP, surely you recognize that the OIF liaison itself is
an opportunity for that review to occur.

Many individuals have participated in routing for optical networks over the
last several years in IETF, ITU-T, T1X1 and OIF, including yourself.  That
the OIF has entertained routing contributions is no secret.  Further, since
OIF and IETF are working with G.7715 and G.7715.1 compliance in mind, the
OIF work should yield improvements that can benefit everyone in this area.
Again, this shouldn't be a cause of alarm from an organization that has
"running code" as a principle.  So, I don't see the need for point b).

Your point 1 raises the issue of divergence, and I agree with you that
"rough consensus" is not desirable here.  Having the OIF liaise to the IETF
helps this as does the IETF replying.  Your suggestions to include the ospf
and isis WGs is good advice, as is the suggestion to send a delta.  However
the OIF is working directly from ITU-T requirements recommendations and
would likely use the liaison process.

stephen:


actually, i disagree with your suggestion, and this
for three reasons:

1) you're part of the ason routing design team so you
    should be aware that there is an effort to avoid
    another protocol clash (and this independently of
    its origin since the result is the same) and thus
    the aim is to converge from the early beginning -
    this has been re-stated during the last ccamp wg

2) yes, there is a clear concern about the "right way"
    to approach a given problem, during the last iet59
    meeting, w/i each non-protocol specific wg where
    protocol(s) procedures/extensions and usage were
    proposed exactly the same concern was raised - so
    i would even include ospf wg (and is-is wg in case)
    in the loop -

3) if oif wants to put their requirement and solution
    on the fast track nothing prevents they submit their
    solution as an internet draft but from the below
    proposal it seems much better they deliver their
    delta requirements so that ietf could address both
    oif and itu-t needs at once (btw these requirements
    should be aligned from an architectural but also
    functional perspective since they were already
    backed up from each other)

On point b) below, the OIF is a Rec. A5 qualified organization with the ITU-T and has liaised work many times with SG15 of the ITU-T. In several meetings in 2002, the OIF voted to adopt ASON architecture and requirements (including G.7715 on routing) for its Implementation Agreements to comply with. It should not alarm CCAMP that the OIF also has a cooperative relationship with ITU-T with regard to ASON routing. Hence I suggest removing point b).
