This document specifies extensions to OSPF Traffic Engineering
to include delay, loss, and current bandwidth utilization metric
that can be taken into account when performing traffic engineering.
Working Group Summary:
There has been much discusson as to how these metrics would be
collected and how they will be used. These topics were deemed to
to be out of scope.
There was also concern for potential overhead of collecting
and flooding these metrics. In response, the draft contains
guidance as to how often the measurements should be collected and
flooded. Additionally, the draft now recommends configuration
to control measurement usage and the thresholds for advertisement.
Finally, the draft was updated to include applicability to
Advanced Multipath links.
It should be noted that, consistent with the long-held IESG policy,
there is a partner I-D for extensions to IS-IS
This document has been a WG document for a little under two years.
It is stable, without changes to the technical solution for more
than six months.
Acee Lindem is the Document Shepherd.

the IESG should be aware of? For example, perhaps he or she is
uncomfortable with certain parts of the document, or has concerns
whether there really is a need for it. In any event, if the WG has
discussed those issues and has indicated that it still wishes to

(10) Has anyone threatened an appeal or otherwise indicated extreme
discontent? If so, please summarise the areas of conflict in
separate email messages to the Responsible Area Director. (It
should be in a separate email because this questionnaire is
(11) Identify any ID nits the Document Shepherd has found in this
document. (See http://www.ietf.org/tools/idnits/ and the
Internet-Drafts Checklist). Boilerplate checks are not enough;
this check needs to be thorough.
Nits are all resolved.
(12) Describe how the document meets any required formal review
criteria, such as the MIB Doctor, media type, and URI type reviews.
(13) Have all references within this document been identified as either
normative or informative?
(14) Are there normative references to documents that are not ready for
advancement or are otherwise in an unclear state? If such
normative references exist, what is the plan for their completion?
(15) Are there downward normative references references (see RFC 3967)?
If so, list these downward references to support the Area Director
in the Last Call procedure.
(16) Will publication of this document change the status of any existing
RFCs? Are those RFCs listed on the title page header, listed in
the abstract, and discussed in the introduction? If the RFCs are
not listed in the Abstract and Introduction, explain why, and point
to the part of the document where the relationship of this document
to the other RFCs is discussed. If this information is not in the

(17) Describe the Document Shepherd's review of the IANA considerations
section, especially with regard to its consistency with the body of

IANA registries. Confirm that any referenced IANA registries have
been clearly identified. Confirm that newly created IANA registries
include a detailed specification of the initial contents for the
registry, that allocations procedures for future registrations are
defined, and a reasonable name for the new registry has been
suggested (see RFC 5226).
This document defines seven new OSPF Traffic Engineering sub-TLVs
that are applicable to the OSPF TE Link TLV.
(18) List any new IANA registries that require Expert Review for future
allocations. Provide any public guidance that the IESG would find
useful in selecting the IANA Experts for these new registries.
(19) Describe reviews and automated checks performed by the Document
Shepherd to validate sections of the document written in a formal
language, such as XML code, BNF rules, MIB definitions, etc.
