Working Group, authors,

The authors of draft-zulr-mpls-tp-linear-protection-switching
(http://tools.ietf.org/html/draft-zulr-mpls-tp-linear-protection-
switching) are looking to publish their document as an Independent
Stream RFC. The MPLS Working Group was informed about this on the
MPLS working group mailing (see below).


The MPLS Working Group decided to progress a Proposed Standard RFC for
MPLS-TP Linear protection Switching (RFC 6378). This is still the
Working Group consensus.  Further there is work-in-progress to update
RFC 6378 to match the functionality of APS.

However it is a long standing tradition to publish documents that were
not progressed as working group RFCs, particularly if they have been
implemented and deployed. This for example is done for the historic
record and due to the value of documenting deployed solutions.

This is the case with  draft-zulr-mpls-tp-linear-protection-switching.
The document clearly states that IETF Standard Track MPLS-TP Linear
Protection is specified in RFC 6378. It also states that the protocol
specified in the draft is a non-IETF pre-standard protocol.

The MPLS working group chairs are therefore not opposed to the
publication of the document as an RFC on the Independent Stream.

The Working Group chairs invite the working group to comment on this,
please send comments to the working group mailing list ([e-mail])
