I can not foresee any process which would come to an actual agreement
on a recommendation from the RRG, and therefore conclude that the
survey is probably the most effective outcome we can achieve as a
community.
While I agree there's probably not agreement of a specific technical
proposal, what about architectural direction(s)? E.g. I thought we
did have
rough consensus on the need for the separation of location and
identity?
True, the workshop a couple of years back (Amsterdam?) I think already
recommended this, so we're not breaking a lot of new ground there;
still, it
would be useful to re-affirm that conclusion, in a larger group.
(I'm sweeping through all RRG exchanges trying to collect the arch
related issues) I saw Tony already confirmed this point earlier: yes
we have a rough consensus on documenting the need for separating
location and identity.
However I also see gap/ambiguity still exists on concept and
terminology. devils always in details. I believe when Noel mentioned
"identity" he probably had in mind some entity identity (there has
been debate on whether host identity or stack identity), not interface
identity (that'd move us back to address)
And how about IPv4 support? Is a solution which doesn't support IPv4
judged to
be plausible? Do most people agree with that one?
(personal opinion) pragmatically we need solutions to keep today's IP4
world going. IP6 rollout is likely to be a very loooong process.
Also, can we say anything about CEE/CES? I think a lot of people
think that
CES is sort of necessary for the short term, because any solution
will never
really get deployed otherwise. At the same time, there appear to be
reasons
that a solution has to be able to migrate in the CEE direction in
the long
term. I don't know how many agree with these, but it might be worth
exploring
that.
(again personal opinion) to me it's a markable step to classify
various proposals into CEE/CES. It may all look obvious now, but two
years back we did not have such a clear view.
As Joel pointed out, CEE/CES is not architecture per se by itself.
However in our report writing, I see CEE/CES useful as it can help
sort out different types of solutions, and we can explain the
different design tradeoffs made by each type.
