[Ballot comment]
More or less editorial comments:

1) These two MUSTs are actually hard to "ensure" and should probably be SHOULDs or lower case musts:
sec 6.1.1: "A Diameter endpoint that supports the Diameter Load mechanism MUST
  include a Load report of type HOST in sufficient answer messages to
  ensure that all consumers of the load information receive timely
  updates."
sec 6.1.2: "A Diameter Agent that supports the Diameter Load mechanism MUST
  include a PEER Load report in sufficient answer messages to ensure
  that all users of the load information receive timely updates."

2) This part also seems hard to realize (in sections 6.1.1. and 6.1.2):
"The LOAD value should be calculated in a way that reflects the
  available load independently of the weight of each server, in order
  to accurately compare LOAD values from different nodes.  Any specific
  LOAD value needs to identify the same amount of available capacity,
  regardless the Diameter node that calculates the value.

  The mechanism used to calculate the LOAD value that fulfills this
  requirement is an implementation decision."

3) I don't think you can require this for all diameter nodes (as they might not implement this extension):
"A Diameter node MUST be prepared to process Load reports of type HOST
  and of type PEER"
  Just remove the sentence or at least don't use normative language.
Side note: This MUST as well as the ones above are like saying "A node that implements/complies to this spec MUST implement this spec". It not really necessary to say this.

OLD:

  The DIME working group explicitly chose not to fulfill these
  requirements in DOIC due to several reasons.

NEW:

  The DIME working group explicitly chose not to fulfill these
  requirements when publishing DOIC [RFC7683] due to several reasons.

- pay attention to the consistency of Load versus load trough out the document.

(Via drafts-lastcall@iana.org): IESG/Authors/WG Chairs:

The IANA Services Operator has completed its review of draft-ietf-dime-load-07.txt. If any part of this review is inaccurate, please let us know.

The IANA Services Operator has a question about one of the actions requested in the IANA Considerations section of this document.

The IANA Services Operator understands that, upon approval of this document, there are two actions which we must complete.

First, in the AVP Codes subregistry of the Authentication, Authorization, and Accounting (AAA) Parameters registry located at:

https://www.iana.org/assignments/aaa-parameters/

three new AVP Codes are to be registered as follows:

AVP Code: [ TBD-at-registration ]
Attribute Name: Load
Reference: [ RFC-to-be ]

AVP Code: [ TBD-at-registration ]
Attribute Name: Load-Type
Reference: [ RFC-to-be ]

AVP Code: [ TBD-at-registration ]
Attribute Name: Load-Value
Reference: [ RFC-to-be ]

IANA Question --> Section 7.4 of the current draft states that: "The SourceID AVP is defined in [I-D.ietf-dime-agent-overload]. It is used to identify the Diameter node that sent the Load report." is the SourceID AVP to be registered upon approval of this draft, or should it wait for the approval of the other draft [I-D.ietf-dime-agent-overload]?

Because this registry requires Expert Review [RFC5226] for registration, we've contacted the IESG-designated expert in a separate ticket to request approval. Expert review should be completed before your document can be approved for publication as an RFC.

Second, Section 7.5 describes Attribute Value Pair flag rules for the new AVP Codes.

IANA QUESTION --> Is there a specific action for IANA in section 7.5 of the current draft, or is it documentation for implementers?

The IANA Services Operator understands that these two actions are the only ones required to be completed upon approval of this document.
Note:  The actions requested in this document will not be completed until the document has been approved for publication as an RFC. This message is only to confirm what actions will be performed.

Thank you,

Sabrina Tanamal

Subject: Last Call:  (Diameter Load Information Conveyance) to Proposed Standard


The IESG has received a request from the Diameter Maintenance and
Extensions WG (dime) to consider the following document:
- 'Diameter Load Information Conveyance'
  as 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@ietf.org mailing lists by 2017-02-27. Exceptionally, comments may be
sent to iesg@ietf.org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.

Abstract


  This document defines a mechanism for conveying of Diameter load
  information.  RFC7068 describes requirements for Overload Control in
  Diameter.  This includes a requirement to allow Diameter nodes to
  send "load" information, even when the node is not overloaded.
  RFC7683 (Diameter Overload Information Conveyance (DOIC)) solution
  describes a mechanism meeting most of the requirements, but does not
  currently include the ability to send load information.

Changes are expected over time. This version is dated …
As required by RFC 4858, this is the current template for the Document
Shepherd Write-Up.

Changes are expected over time. This version is dated 24 February 2012.

(1) What type of RFC is being requested (BCP, Proposed Standard,
Internet Standard, Informational, Experimental, or Historic)?  Why
is this the proper type of RFC?  Is this type of RFC indicated in the
title page header?

  The document is Standards Track. This is stated on the title page.

(2) 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 announcement contains the following sections:

Technical Summary

  This document defines a mechanism for conveying of Diameter load
  information. RFC7683 (DOIC) decided not to address load information
  delivery. This document fills that gap.

Working Group Summary

  The document had extensive discussion on the email reflector and there
  is working group support behind the documented solution. It is worth
  noting that Diameter experts from other SDOs (3GPP) also participated
  actively to the discussion.

Document Quality

  The specification is a natural extension to DOIC mechanism, which is
  already adopted by 3GPP standards.

  No specific reviews have been requested or carried out by
  different directorates.

Personnel

  Jouni Korhonen (jouni.nospam@gmail.com) is the document shepherd.
  Stephen Farrell (stephen.farrell@cs.tcd.ie) is the responsible AD.

(3) Briefly describe the review of this document that was performed by
the Document Shepherd.  If this version of the document is not ready
for publication, please explain why the document is being forwarded to
the IESG.

  Document shepherd has reviewed the -06 version of the document
  and thinks it is in a good enough state to be published.

(4) Does the document Shepherd have any concerns about the depth or
breadth of the reviews that have been performed?

  No.

(5) Do portions of the document need review from a particular or from
broader perspective, e.g., security, operational complexity, AAA, DNS,
DHCP, XML, or internationalization? If so, describe the review that
took place.

  The document would benefit from a review by AAA Doctors.

(6) Describe any specific concerns or issues that the Document Shepherd
has 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 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 advance the document, detail those
concerns here.

  None.

(7) Has each author confirmed that any and all appropriate IPR
disclosures required for full conformance with the provisions of BCP 78
and BCP 79 have already been filed. If not, explain why.

  All three authors have responded they are not aware of any IPRs.

(8) Has an IPR disclosure been filed that references this document?
If so, summarize any WG discussion and conclusion regarding the IPR
disclosures.

  No.

(9) 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 agree with it? 

  The document has been discussed in length in the WG with external
  SDO (3GPP) experts also actively joining the discussion. The
  consensus behind the document is solid.

(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 publicly available.)

  No.

(11) Identify any ID nits the Document Shepherd has found in this
document. (See https://www.ietf.org/tools/idnits/ and the Internet-Drafts
Checklist). Boilerplate checks are not enough; this check needs to be
thorough.

  None of the issues found by IDnits require any specific action.
  Old references will be automatically corrected when a new version
  gets produced by the RFC Editor.

(12) Describe how the document meets any required formal review
criteria, such as the MIB Doctor, media type, and URI type reviews.

  None.

(13) Have all references within this document been identified as
either normative or informative?

  Yes.

(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?

  This specification has a normative reference to
  draft-ietf-dime-agent-overload (and that document has a normative
  reference to this document). These two documents need to be
  progressed in parallel. Both documents are considered ready from
  the DIME WG point of view.

(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.

  No.

(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 document,
explain why the WG considers it unnecessary.

  No.

(17) Describe the Document Shepherd's review of the IANA considerations
section, especially with regard to its consistency with the body of the
document. Confirm that all protocol extensions that the document makes
are associated with the appropriate reservations in 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 specification requires an assignment of four new AVP Codes.
  No new registries are created and no new values are needed
  from existing registries.

(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.

  None.

(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.

  None.

Dear Authors and Contributors,

Before proceeding with the photo write-up on draft-ietf-dime-load-03, I would like to check whether there are any claims of Intellectual Property Rights (IPR) on the document.

Are you personally aware of any IPR that applies to draft-ietf-dime-agent-overload-06?  If so, has this IPR been disclosed in full conformance with the provisions of BCP 78 and BCP 79?  (See RFCs 3979, 4879, 3669, and 5378 for more details.) If IPR disclosures have not been filed, please explain why.

Online tools for filing IPR disclosures can be found at .

Jouni & Lionel
