I see some difficulties with the references in this I-D.
a) The security section of this I-D says
see [I-D.ietf-mpls-mpls-and-gmpls-security-framework]
which is an informative reference.
I believe that security should be normative, not informative, even in this, a
requirements (as opposed to a protocol) draft.
b) The terminology section of this draft overlaps with that in an Informational
Reference [I-D.helvoort-mpls-tp-rosetta-stone] "A Thesaurus for the Terminology
used in MPLS-TP drafts/RFCs and ITU-T's Transport Network Recommendations."
(now republished as a Working Group Draft)
which will doubtless progress to an RFC but as Informational. I see this as
problematic; the two may be in step now but I am doubtful that they will be as
and when this last gets amended in the course of its development. The mpls-tp
list has seen some vigorous debate already about the meaning of terms (eg
associated bidirectional, AIS). Sometimes, the same concept has a different
term in IETF versus ITU-T (versus IEEE) while the same term may also be used for
a different concept.
RFC4397 is the product of a similar, earlier issue and is another potential
overlap.
The definitions in this I-D may be normative for this I-D but if they
diverge from definitions in other I-Ds, we are storing up problems for the
future.
On balance, I believe that this rosetta-stone should be a Normative Reference,
ideally removing the overlapping definitions.

The IESG has received a request from the Multiprotocol Label Switching WG
(mpls) to consider the following document:
- 'MPLS-TP Requirements '
<draft-ietf-mpls-tp-requirements-09.txt> as a Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf(_at_)ietf(_dot_)org mailing lists by 2009-07-16. Exceptionally,
comments may be sent to iesg(_at_)ietf(_dot_)org instead. In either case,
please
retain the beginning of the Subject line to allow automated sorting.
