Hi Lixia -
I certainly agree with your winning strategy. And if you prefer not
to
discuss identifiers on this mailing list, so be it.
it is not an issue of any individual's preference.
Rather,
- this list got its own mission to accomplish;
and perhaps more importantly,
- it is unclear whether people who know more about the higher level
requirements on identifiers are watching this list.
agree?
I still would like to observe, though, that a good understanding of
what
needs to be identified may prove helpful in devising the locators that
must lead to the things being identified.
agree on the good understanding part.
I avoid the word "locator", as what we have in hand is simply IP
addresses, whose basic function is to identify the attachment point of
destinations to which IP packets are delivered, independent from which
identifier resolved to that delivery address.
make sense?
This said, I do understand your impatience to bring the discussion to
the core topic of this research group.
impatience? not sure what led to that... maybe my poor English
expressions. but honest, I have all the patience:-)
my goal is trying to focus the attention on our own mission (I assume
everyone still remembers that we have this March deadline for a
routing scalability recommendation:)
This, in fact, reminds me of a
result from the Dagstuhl workshop in March, which the research group
didn't yet evaluate -- namely, the following set of locator
properties:
- topologically sensitive
- multihoming‐capable
- local and constant cost for topological changes
Would a discussion of these locator properties be in scope?
of course.

- since god did not write us a bible on how to design networks, we
have
to learn as we go. And one of the things I have learned from last
30 years: never be too sure about the future's need. A winning
strategy seems including the following ingredients: + start simple,
and + stay flexible, keep the mind open.
Along that line of thought: we need to understand the interplay
between
address (used for routing) and this forthcoming identifier thing,
but I
would keep the focus on address/routing, not nailing down the exactly
numbers and definitions of identifiers.
