Subject: Re: MPLS

Dear Malcolm:

Thanks for getting this posted.  It has already gotten a lot of visibility.

Just to make sure that we are on the same page, I'd like to repeat two
things that came up while we were drafting the newslog article.  These
also reflect the IETF's understanding of the newslog article.  I'll
forward this note to the IETF participants to be sure that we're all
in sync here.

First, the text of the newslog article re-affirms the JWT agreement
from 2008 as captured in RFC 5317.  In particular, the IETF standards
process will continue to be used for all MPLS-TP architecture and
protocol documents.

Second, since G.8113.1 contains a protocol that is not a product of
the IETF standards process, it cannot be a part of MPLS-TP according
to the conditions of the JWT agreement and the newslog article.  The
IETF anticipates one of the following actions will be taken to
conform to this agreement.  Either (1) G.8113.1 will be withdrawn, or
(2) the title of G.8113.1 will be changed, and the content will be
revised to reflect that it is not included as part of MPLS or MPLS-TP
protocol suite..

Also, thanks for sending me the TD527/P document from the SG15
Chairman.  I note that it proposes the progression of both G.8113.1
and G.8113.2 as MPLS standards.  This approach is not consistent with
the JWT agreement or the newslog article.

I believe this is a constructive step forward.  I look forward to a
resolution that fully respects the JWT agreement and moves our two
organizations further toward collaborative standards development.
