RE: SONET/SDH label agreement for IETF, ITU-T and OIF

["Natale, Robert C (Bob)" <bnatale@lucent.com>]

Hi,

Apologies in advance for this post going against the
grain of the AD's guidance for this thread.  I am not
(I hope!) posting a "diatribe" here :-) -- I am just
curious about something and maybe the answer to it
will affect my own and possibly others' assessment
of the options before us....

As a non-expert (re the diffs between SONET and SDH as
they might necessarily affect labeling requirements or
not), I opted for #1 (or #4, which I consider to be its
moral equivalent) on the basis of my interpretation of
s/w engineering principles and my (negative) experience
with allowing optionality in widely deployed standards.

Since the respondents seems largely divided between
#1 and #2 (with the few mentioning #4 as an acceptable
alternative about equally divided between #1 and #2
as another acceptable choice for them), my attention
is naturally drawn to the absence of any "votes" for
#3 (apologies if I've missed anyone's vote for #3)...?

The only diff that I can discern between #2 and #3 is
the SHOULD in #2 vs the MUST in #3.  It is that SHOULD
in #2 that caused me to discount it up front.  I am
curious to know how the people expressing a preference
for #2 feel about #3 -- that is, do they see it important
that we specify #2 rather than #3, or rather than #1?

I'm really against that SHOULD in #2.  But -- although
I do prefer #1 (or, second, #4) for the reasons mentioned
above -- I might not feel as determinedly antagonistic
to #3, if that were to end up being the WG's consensus.

Thanks,

BobN
