Proto-write-up for draft-ietf-pce-policy-enabled-path-comp-03

Intended status : Informational

> (1.a)  Who is the Document Shepherd for this document?  Has the
>        Document Shepherd personally reviewed this version of the

Adrian Farrel is the document shepherd.
He has personally reviewed the I-D and believes it is ready for
forwarding to the IESG for publication.

> (1.b)  Has the document had adequate review both from key WG members
>        and from key non-WG members?  Does the Document Shepherd have
>        any concerns about the depth or breadth of the reviews that
>        have been performed?

This document has been reviewed by the PCE working group, although the
number of people in the working group with a deep understanding of
policy is limited.

In order to broaden the review, we sent the document to the IPSphere
forum who are more experienced in these matters. We received comments
back from two members and the document was updated accordingly.

> (1.c)  Does the Document Shepherd have concerns that the document
>        needs more review from a particular or broader perspective,
>        e.g., security, operational complexity, someone familiar with
>        AAA, internationalization or XML?

No concerns.

> (1.d)  Does the Document Shepherd have any specific concerns or
>        issues with this document that the Responsible Area Director
>        and/or the IESG should be aware of?  For example, perhaps he
>        or she is uncomfortable with certain parts of the document, or

The document is sound.

The working group chairs were not completely convinced that there was
a need for this document, but members of the working group were
supportive, and it is certainly true that policy is discussed within
the PCE architecture (RFC 4655) and is very applicable for inter-AS
PCE.

> (1.e)  How solid is the WG consensus behind this document?  Does it
>        represent the strong concurrence of a few individuals, with
>        others being silent, or does the WG as a whole understand and

There were no problems with consensus for this document.

When the I-D was accepted by the WG there was strong support.

> (1.f)  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
>        entered into the ID Tracker.)

No threats. No discontent.

> (1.g)  Has the Document Shepherd personally verified that the
>        document satisfies all ID nits?  (See
>        http://www.ietf.org/ID-Checklist.html and
>        http://tools.ietf.org/tools/idnits/).  Boilerplate checks are

>        met all formal review criteria it needs to, such as the MIB
>        Doctor, media type and URI type reviews?

All checks made.

> (1.h)  Has the document split its references into normative and
>        informative?  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

>        so, list these downward references to support the Area
>        Director in the Last Call procedure for them [RFC3967].

References split.
No downrefs.

> (1.i)  Has the Document Shepherd verified that the document IANA
>        consideration section exists and is consistent with the body
>        of the document?  If the document specifies protocol
>        extensions, are reservations requested in appropriate IANA

>        can appoint the needed Expert during the IESG Evaluation?

This is an Informational I-D.
A null IANA section is present.

> (1.j)  Has the Document Shepherd verified that sections of the
>        document that are written in a formal language, such as XML
>        code, BNF rules, MIB definitions, etc., validate correctly in
>        an automated checker?

No such sections.

> (1.k)  The IESG approval announcement includes a Document
>        Announcement Write-Up.  Please provide such a Document
>        Announcement Write-Up.  Recent examples can be found in the
>        "Action" announcements for approved documents.  The approval

The Path Computation Element (PCE) Architecture (RFC 4655) introduces
the concept of policy in the context of path computation. This
document provides additional details on policy within the PCE
Architecture and also provides context for the support of PCE Policy.
This document introduces the use of the Policy Core Information Model
(PCIM) as a framework for supporting path computation policy. This
document also provides representative scenarios for the support of
PCE Policy.

>        Working Group Summary
>           Was there anything in WG process that is worth noting?  For
>           example, was there controversy about particular points or
>           were there decisions where the consensus was particularly
>           rough?

Nothing of note.

>        Document Quality
>           Are there existing implementations of the protocol?  Have a
>           significant number of vendors indicated their plan to
>           implement the specification?  Are there any reviewers that
>           merit special mention as having done a thorough review,
>           e.g., one that resulted in important changes or a
>           conclusion that the document had no substantive issues?  If
>           there was a MIB Doctor, Media Type or other expert review,
>           what was its course (briefly)?  In the case of a Media Type
>           review, on what date was the request posted?

This is an Informational I-D with no protocol specifications.
Expert policy review was provided by Christian Jacquenet from France
Telecom who is a participant in the IPSphere forum.

Hi JL,

In Vancouver you said you had some thoughts and issues with the P2MP PCEP 
drafts draft-yasukawa-pce-p2mp-app-01.txt and 
draft-yasukawa-pce-p2mp-req-04.txt.

The main issue that you raised at the microphone was that you felt that the 
I-Ds were too strong in their assertion that P2MP computation would never be 
done at a head-end LSR.

Looking back at the I-Ds, I see that the requirements draft makes no claims 
about the applicability of the PCE architecture to P2MP LSP computation: it 
devolves this responsibility to the applicability I-D.

The applicability I-D does discuss the potentially greater computational 
load for P2MP LSPs compared to P2P LSPs. It states:
   Roughly speaking, the load to compute a least-cost-to-leaf tree is
   the same as the cost to compute a single optimal path to each leaf in
   turn. The load to compute a Steiner tree is approximately an order of
   magnitude greater.

>From what you said in Vancouver, you are suggesting that approximations to 
Steiner may be achieved in roughly the same order of magnitude as a 
least-cost-to-leaf tree. Would be enough to you if we added to this 
paragraph to say...
   ...although powerful heuristics exist that may make it possible
   to approximate a Steiner tree in the same computational time
   as a least-cost-to-leaf tree.

Were there any other issues you wanted to raise?

Cheers,
Adrian
