[Ballot comment]
Thanks for working on this specification. Thanks to Wesley Eddy for his TSVART review. I think this specification is OK to publish from tranpsport protocol perspective.

However, this specification deprecates tcpOptions IE without updating (or obsolating) RFC 5102, so I am unsure about the operational issues and usage of the new IEs when we have tcpOption IE. Hence supporting Paul's discuss.



One question - 

- Section 4.1: it says
    "This approach allows an observer to export any observed TCP option even if it does support that option and without requiring updating a mapping table"

  Do you mean "even if it does *not* support that option"?

        This specification deprecates the ipv6ExtensionHeaders IPFIX IE
        in favor of the new IEs defined in this document.

I don't see which RFC those were in, because this document does not
Update: or Obsolete: the RFC that defined the ipv6ExtensionHeaders IPFIX IE

[Ballot comment]
Thanks for this document. I have one suggestion -- even though the update to the IANA registry is sufficient to deprecate ipv6ExtensionHeaders and tcpOptions, it seems to me it would be a courtesy to future users of RFC 5102 if you also used the Updates: header to indicate that 5102 is updated to deprecate these elements, instead of requiring them to discover this (perhaps late in their journey) by examining the registry.

(Now that I look at this a little harder, I see that although the registry points to 5102, that RFC is obsoleted by 7012, so the chain of pointers is already messy. It would still be nice to use Updates: but presumably pointing to 7012... and I wonder if the registry should be updated to reference 5102 throughout, the note at the top of it notwithstanding. But that is a problem for another day.)

** Section 8.2.  This section is under-specified and contains typos relevant to registration.

-- The "IPFIX Information Elements" registry doesn’t have a “Value” field.  It is “ElementID”

-- The mandatory elements of the "IPFIX Information Elements" registry defined in the registration template of Section 2.1 of RFC7012 are missing – description, datatype, and status.  I appreciate that the first two in this list are found in their respective sections.  However, there is no guidance to IANA to extract those values as such.

-- Per the Reference field value, is a section number permitted?  No other current entry in this registry includes a section number.  The definition of references from RFC7012 doesn’t seem to account for it either -- “reference - Identifies additional specifications that more precisely define this item or provide additional context for its use.”

### S3.6

* "reported that IPv6 packets with extension headers are often dropped"

  A useful citation here might be RFC 7872, "Observations on the Dropping of
  Packets with IPv6 Extension Headers in the Real World".

## Nits

### S3.4

* "the occurrences of the Fragment headers" ->
  "the occurrence of the Fragment header"

  to match the example scenario's description.

# Éric Vyncke, INT AD, comments for draft-ietf-opsawg-ipfix-tcpo-v6eh-16

Thank you for the work put into this document.

Please find below one blocking some non-blocking COMMENT points (but replies would be appreciated even if only for my own education), and one nit.

Special thanks to Thomas Graf for the shepherd's detailed write-up including the WG consensus and the justification of the intended status.

I hope that this review helps to improve the document,

Regards,

# COMMENTS (non-blocking)

## Section 3

Suggest using the IE acronym rather than "Information Element" in the subsections of this section.

## Section 3.1

s/Type of an IPv6 extension header observed *in packets* of this Flow./Type of an IPv6 extension header observed *in at least one packet* of this Flow./ ? (or "in some packets")

## Section 3.2

I was wondering about this IE and the previous one as they looked quite atomic (plus the use of "consecutive") until I read the specification of ipv6ExtensionHeaderTypeCountList. Suggest adding a forward reference to section 3.4 and add some text that those 2 IEs can only occur in ipv6ExtensionHeaderTypeCountList. E.g., "This atomic IE MAY only occur in ipv6ExtensionHeaderTypeCountList as specified in section 3.4".

## Section 3.3

It took me to read until section 8.4.1 to understand the the bit number is *NOT* the extension header type per RFC 8200. It is really confusing with `The "No Next Header" (59) value` text, which I also read as bit 59.

Strongly suggest adding a note on the value referring to NEW_IPFIX_IPv6EH_SUBREGISTRY not only in "Additional Information" but in "Description" (as it is really normative).

## Section 3.4

`How an implementation disambiguates between unknown upper-layer protocols vs. extension headers is not IPFIX-specific` is true but why not specifying the expected behavior of the collector at least? Citing RFC 8883 as an example, does not really help in a PS. Alternatively, the IANA NEW_IPFIX_IPv6EH_SUBREGISTRY could redefine UNK as "unknown extension or transport header".

## Sections 3.5 & 3.6

Excellent idea :-) Thanks

## Missing RH Type ?

It would be really to be able to also export the Routing Header type, perhaps in an optional new IE following ipv6ExtensionHeaderType in the list or by adding more values in NEW_IPFIX_IPv6EH_SUBREGISTRY (cfr also section 8.4.2 `For example, a registration may request two bits for a new EH to cover specific behaviors or uses of that EH.`)?

## Section 4.1

`The value of tcpOptionsFull IE may be encoded in fewer octets` should it rather be a "SHOULD" (with explanations about the consequences of bypassing the SHOULD) ?

s/The presence of tcpSharedOptionExID16List or tcpSharedOptionExID32List IEs is an indication that a shared TCP option (Kind=253 or 254) is observed in a Flow./The presence of tcpSharedOptionExID16List (Kind=253) or tcpSharedOptionExID32List (Kind=254) IEs is an indication that a shared TCP option is observed in a Flow./ ?

## Sections 4.2 and 4.3

Same comment as in sections 3.2 and 3.3.

## Section 5

Should it be an "Implementation Consideration" ?

# NITS (non-blocking / cosmetic)

## Section 3.4

Should plural form be used for "header" in the example ?

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

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

IANA has completed its review of draft-ietf-opsawg-ipfix-tcpo-v6eh-15; we had also previously reviewed -11. If any part of this review is inaccurate, please let us know.

IANA understands that, upon approval of this document, there are five actions which we must complete.

First, in the IPFIX Information Elements registry in the IP Flow Information Export (IPFIX) Entities registry group located at:

https://www.iana.org/assignments/ipfix/

the entry for ipv6ExtensionHeaders IE (ElementID: 64) will be marked as deprecated and its reference changed to [ RFC-to-be ]. In addition, the "Additional Information" field for this deprecated entry will show that it is deprecated in favor of ipv6ExtensionHeadersFull IE as defined in this draft.

As this document requests changes in an Expert Review or Specification Required (see RFC 8126) registry, we have initiated and completed the required Expert Review via a separate request. We also understand that the changes in -15 are as a result of feedback from the experts.

Second, also in the IPFIX Information Elements registry in the IP Flow Information Export (IPFIX) Entities registry group located at:

https://www.iana.org/assignments/ipfix/

the entry for tcpOptions IE (ElementID: 209) will be marked as deprecated and its reference changed to [ RFC-to-be ]. In addition, the "Additional Information" field for this deprecated entry will show that it is deprecated in favor of tcpOptionsFull IE as defined in this draft.

As this also requests registrations in an Expert Review or Specification Required (see RFC 8126) registry, we have initiated and completed the required Expert Review via a separate request. We also understand that the changes in -15 are as a result of feedback from the experts.

Third, also in the IPFIX Information Elements registry in the IP Flow Information Export (IPFIX) Entities registry group located at:

https://www.iana.org/assignments/ipfix/

twelve new registrations will be made as follows:

Value Name Reference
-----+-----+-----------
[ TBD-at-Registration ] ipv6ExtensionHeader [ RFC-to-be; Section 3.1 ]
[ TBD-at-Registration ] ipv6ExtensionHeaderCount [ RFC-to-be; Section 3.2 ]
[ TBD-at-Registration ] ipv6ExtensionHeadersFull [ RFC-to-be; Section 3.3 ]
[ TBD-at-Registration ] ipv6ExtensionHeaderTypeCountList [ RFC-to-be; Section 3.4 ]
[ TBD-at-Registration ] ipv6ExtensionHeadersLimit [ RFC-to-be; Section 3.5 ]
[ TBD-at-Registration ] ipv6ExtensionHeadersChainLength [ RFC-to-be; Section 3.6 ]
[ TBD-at-Registration ] ipv6ExtensionHeaderChainLengthList [ RFC-to-be; Section 3.7 ]
[ TBD-at-Registration ] tcpOptionsFull [ RFC-to-be; Section 4.1 ]
[ TBD-at-Registration ] tcpSharedOptionExID16 [ RFC-to-be; Section 4.2 ]
[ TBD-at-Registration ] tcpSharedOptionExID32 [ RFC-to-be; Section 4.3 ]
[ TBD-at-Registration ] tcpSharedOptionExID16List [ RFC-to-be; Section 4.4 ]
[ TBD-at-Registration ] tcpSharedOptionExID32List [ RFC-to-be; Section 4.5 ]

As this also requests registrations in an Expert Review or Specification Required (see RFC 8126) registry, we have initiated and completed the required Expert Review via a separate request. We also understand that the changes in -15 are as a result of feedback from the experts.

Fourth, in the IPFIX Information Element Data Types registry also in the IP Flow Information Export (IPFIX) Entities registry group located at:

https://www.iana.org/assignments/ipfix/

s single new registration will be made as follows:

Value: [ TBD-at-Registration ]
Description: unsigned256
Reference: [ RFC-to-be ]

Fifth, a new registry is to be created called the ipv6ExtensionHeaders Bits registry. The new registry will be located in the IP Flow Information Export (IPFIX) Entities registry group located at:

https://www.iana.org/assignments/ipfix/

The registry procedure for the new registry is Expert Review as defined in RFC8126.

There are initial values for the new registry as follows:

Protocol
Bit Label Number Description Reference
--+-----+--------+----------+-----------
0 DST 60 Destination Options for IPv6 [ RFC-to-be ]
1 HOP 0 IPv6 Hop-by-Hop Options [ RFC-to-be ]
2 NoNxt 59 No Next Header for IPv6 [ RFC-to-be ]
3 UNK Unknown extension header [ RFC-to-be ]
4 FRA0 44 Fragment header - first fragment [ RFC-to-be ]
5 RH 43 Routing header [ RFC-to-be ]
6 FRA1 44 Fragmentation header - not first fragment [ RFC-to-be ]
7 MOB 135 Mobility Header [ RFC-to-be ]
8 ESP 50 Encapsulating Security Payload [ RFC-to-be ]
9 AH 51 Authentication Header [ RFC-to-be ]
10 HIP 139 Host Identity Protocol [ RFC-to-be ]
11 SHIM6 140 Shim6 Protocol [ RFC-to-be ]
12 253 Use for experimentation and testing [ RFC-to-be ]
13 254 Use for experimentation and testing [ RFC-to-be ]
20 to 255 Unassigned

We understand that these are the only actions 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 meant only to confirm the list of actions that will be performed.

IANA has completed its review of draft-ietf-opsawg-ipfix-tcpo-v6eh-11. If any part of this review is inaccurate, please let us know.

IANA understands that, upon approval of this document, there are five actions which we must complete.

First, in the IPFIX Information Elements registry in the IP Flow Information Export (IPFIX) Entities registry group located at:

https://www.iana.org/assignments/ipfix/

the entry for ipv6ExtensionHeaders IE (ElementID: 64) will be marked as deprecated and its reference changed to [ RFC-to-be ]. In addition, the "Additional Information" field for this deprecated entry will show that it is deprecated in favor of ipv6ExtensionHeadersFull IE as defined in this draft.

As this document requests changes in an Expert Review or Specification Required (see RFC 8126) registry, we have initiated the required Expert Review via a separate request. This review must be completed before the document's IANA state can be changed to "IANA OK."

Second, also in the IPFIX Information Elements registry in the IP Flow Information Export (IPFIX) Entities registry group located at:

https://www.iana.org/assignments/ipfix/

the entry for tcpOptions IE (ElementID: 209) will be marked as deprecated and its reference changed to [ RFC-to-be ]. In addition, the "Additional Information" field for this deprecated entry will show that it is deprecated in favor of tcpOptionsFull IE as defined in this draft.

As this also requests changes in an Expert Review or Specification Required (see RFC 8126) registry, we have initiated the required Expert Review via a separate request. This review must be completed before the document's IANA state can be changed to "IANA OK."

Third, also in the IPFIX Information Elements registry in the IP Flow Information Export (IPFIX) Entities registry group located at:

https://www.iana.org/assignments/ipfix/

nine new registrations will be made as follows:

Value Name Reference
-----------------------+--------------------------------+-------------------------
[ TBD-at-Registration ] ipv6ExtensionHeader [ RFC-to-be; Section 3.1 ]
[ TBD-at-Registration ] ipv6ExtensionHeaderCount [ RFC-to-be; Section 3.2 ]
[ TBD-at-Registration ] ipv6ExtensionHeadersFull [ RFC-to-be; Section 3.3 ]
[ TBD-at-Registration ] ipv6ExtensionHeaderTypeCountList [ RFC-to-be; Section 3.4 ]
[ TBD-at-Registration ] ipv6ExtensionHeadersLimit [ RFC-to-be; Section 3.5 ]
[ TBD-at-Registration ] ipv6ExtensionHeadersChainLength [ RFC-to-be; Section 3.6 ]
[ TBD-at-Registration ] tcpOptionsFull [ RFC-to-be; Section 4.1 ]
[ TBD-at-Registration ] tcpSharedOptionExID16 [ RFC-to-be; Section 4.2 ]
[ TBD-at-Registration ] tcpSharedOptionExID32 [ RFC-to-be; Section 4.3 ]

As this also requests registrations in an Expert Review or Specification Required (see RFC 8126) registry, we have initiated the required Expert Review via a separate request. This review must be completed before the document's IANA state can be changed to "IANA OK."

Fourth, in the IPFIX Information Element Data Types registry also in the IP Flow Information Export (IPFIX) Entities registry group located at:

https://www.iana.org/assignments/ipfix/

s single new registration will be made as follows:

Value: [ TBD-at-Registration ]
Description: unsigned256
Reference: [ RFC-to-be ]

Fifth, a new registry is to be created called the ipv6ExtensionHeaders Bits registry. The new registry will be located in the IP Flow Information Export (IPFIX) Entities registry group located at:

https://www.iana.org/assignments/ipfix/

The registry procedure for the new registry is Expert Review as defined in RFC8126.

There are initial values for the new registry as follows:

Bit Label Protocol Number Description Reference
--+-----+----------------+-----------+-----------
0 DST 60 Destination Options for IPv6 [ RFC-to-be ]
1 HOP 0 IPv6 Hop-by-Hop Options [ RFC-to-be ]
2 NoNxt 59 No Next Header for IPv6 [ RFC-to-be ]
3 UNK Unknown Layer 4 header (compressed, encrypted, not supported) [ RFC-to-be ]
4 FRA0 44 Fragment header - first fragment [ RFC-to-be ]
5 RH 43 Routing header [ RFC-to-be ]
6 FRA1 44 Fragmentation header - not first fragment [ RFC-to-be ]
7 to 11 Unassigned
12 MOB 135 Mobility Header [ RFC-to-be ]
13 ESP 50 Encapsulating Security Payload [ RFC-to-be ]
14 AH 51 Authentication Header [ RFC-to-be ]
15 Unassigned
16 HIP 139 Host Identity Protocol [ RFC-to-be ]
17 SHIM6 140 Shim6 Protocol [ RFC-to-be ]
18 253 Use for experimentation and testing [ RFC-to-be ]
19 254 Use for experimentation and testing [ RFC-to-be ]
20 to 255 Unassigned

We understand that these are the only actions 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 meant only to confirm the list of actions that will be performed.

* 1.1

Add "the":
  Section 3 addresses these issues.  Also, the ipv6ExtensionHeaders IPFIX
  IE is deprecated in favor of the new IEs defined in this document.


* 1.2

Add "the" :
  The specification of the tcpOptions IPFIX IE (209) does not:

Should "option" be "options"? :
  *  Describe how some observed TCP options in a Flow can be exported
      using IPFIX.  Only TCP options having a Kind <= 63 can be exported
      in a tcpOptions IE.

Add "the" :
  Section 4 addresses these issues.  Also, the tcpOptions IE is deprecated
  in favor of the new IEs defined in this document.


* 2

Is the indentation correct here? :
  Extension header chain:  Refers to the chain of extension headers
      that are present in an IPv6 packet.

      This term should not be confused with the IPv6 header chain, which
      includes the IPv6 header, zero or more IPv6 extension headers, and
      zero or a single Upper-Layer Header.


* 3.2

"the same" :
  Description:  The number of consecutive occurrences of the same
      extension header type in a Flow.


* 3.4

Add "ipv6ExtensionHeaderTypeCountList" :
      If several extension header chains are observed in a Flow, each
      header chain MUST be exported in a separate ipv6ExtensionHeaderTypeCountList IE.


* 3.5

What if both ipv6ExtensionHeadersFull and ipv6ExtensionHeaderTypeCountList are exported?
[Later] this is discussed in section 5.1, but that wouldn't be known from reading the IPFIX registry alone. The fact that these IEs are mutually exclusive should be added to both IE descriptions.

  Description:  When set to "false", this Information Element indicates
      that the exported extension headers information (e.g.,
      ipv6ExtensionHeadersFull or ipv6ExtensionHeaderTypeCountList) does
      not match the full enclosed extension headers


* 3.6

Change "identifying" to "to identify" :
      Exporting such information might help
      to identify root causes of performance degradation, including
      packet drops.

How would we know which ipv6ExtensionHeadersChainLength IE corresponds with which header chain?
      If several extension header chains are observed in a Flow, each
      header chain length MUST be exported in a separate
      ipv6ExtensionHeadersChainLength IE.


* 5.1

"Will" sounds like a detail of a particular implementation. More generally this should be a "MUST", a "SHOULD", or a "MAY":
  If an implementation determines that an observed packet of a Flow
  includes an extension header that it does not support, then the exact
  observed code of that extension header will be echoed in the
  ipv6ExtensionHeaderTypeCountList IE (Section 3.4).


* 5.2

What does this mean? :
  If a TCP Flow contains packets with a mix of 2-byte and 4-byte
  Experiment IDs, the same Template Record is used with both
  tcpSharedOptionExID16 and tcpSharedOptionExID32 IEs.


* 6.1

It would be helpful to list the corresponding header bit values, and to list them in order (0, 1, 5) rather than 1, 5, 0:

  Figure 1 provides an example of reported values in an
  ipv6ExtensionHeadersFull IE for an IPv6 Flow in which only the IPv6
  Destination Options header (0) is observed.
  Figure 2 provides another example of reported values in an
  ipv6ExtensionHeadersFull IE for an IPv6 Flow in which the IPv6 Hop-
  by-Hop Options (1), Routing (5), and Destination Options (0) headers are
  observed.


* 6.2

It would be helpful to list the corresponding header bit values:
  Figure 3 shows an example of reported values in a tcpOptionsFull IE
  for a TCP Flow in which End of Option List (0), Maximum Segment Size (2), and
  Window Scale (3) options are observed.

Please use the full 16-bit value, "0348" :
  1.  The tcpSharedOptionExID16 IE set to 0x0348454E to report observed
      2-byte ExIDs: HOST_ID and TCP-ENO ExIDs.


* 8.1

It's unclear which IE "this IE" is. eg, write "IE 209" if that's what's meant.
  *  Update the tcpOptions IE (209) entry by marking it as deprecated
      in favor of the tcpOptionsFull IE defined in this document.  This
      note should also be echoed in the "Additional Information" of this
      IE.


* 8.4

This section sets up a potential conflict: what would happen if a new code was assigned to an IPv6 EH in [IANA-EH], but the expert reviewers disagreed with adding it to IPFIX?

Section 1.1 said, "how to automatically update the IANA IPFIX registry". Is expert review contrary to an automatic update?


* 8.4.1.

# Document Shepherd Write-Up for Group Documents

*This version is dated 10 February 2024.*

Thank you for your service as a document shepherd. Among the responsibilities is
answering the questions in this write-up to give helpful context to Last Call
and Internet Engineering Steering Group ([IESG][1]) reviewers, and your
diligence in completing it is appreciated. The full role of the shepherd is
further described in [RFC 4858][2]. You will need the cooperation of the authors
and editors to complete these checks.

Note that some numbered items contain multiple related questions; please be sure
to answer all of them.

## Document History

1. Does the working group (WG) consensus represent the strong concurrence of a
  few individuals, with others being silent, or did it reach broad agreement?

Within the working group, this document was seen as valuable since it addresses
current limitations of IPFIX entity 209 tcpOptions and 64 ipv6ExtensionHeaders.
OPSAWG reached consensus to deprecate ipv6ExtensionHeaders and tcpOptions as
described in section 8.1 and in introduce new IPFIX entities. Section 8.2
introduces a new IPFIX data type since existing unsigned integers were to small.

2. Was there controversy about particular points, or were there decisions where
  the consensus was particularly rough?

Consesus was achieved without any opposing voice.

3. Has anyone threatened an appeal or otherwise indicated extreme discontent? If
  so, please summarize 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

4. For protocol documents, are there existing implementations of the contents of
  the document? Have a significant number of potential implementers indicated
  plans to implement? Are any existing implementations reported somewhere,
  either in the document itself (as [RFC 7942][3] recommends) or elsewhere
  (where)?

This document defines new IPFIX entities for IPv6 extension headers and TCP
options and a new IPFIX data type. The working group is not aware of any existing
or planned implementations. IPFIX entity 64 ipv6ExtensionHeaders has been
adopted widely. Where IPFIX entity 209 tcpOptions appears to be,
https://mailarchive.ietf.org/arch/msg/opsawg/gaJ9-A6i3Z4grgHT86OUym_DAqA/,
merly used to its ambiguity and deprecated as described in section 8.1 of
this document. It is expected that the new IPFIX entities defined in this document
are going to be implemented.

## Additional Reviews

5. Do the contents of this document closely interact with technologies in other
  IETF working groups or external organizations, and would it therefore benefit
  from their review? Have those reviews occurred? If yes, describe which
  reviews took place.

Yes, the document received

Transport area
https://datatracker.ietf.org/doc/review-ietf-opsawg-ipfix-tcpo-v6eh-05-tsvart-early-eddy-2024-01-02/

OPS area
https://datatracker.ietf.org/doc/review-ietf-opsawg-ipfix-tcpo-v6eh-05-opsdir-early-qu-2024-01-04/

Internet area
https://datatracker.ietf.org/doc/review-ietf-opsawg-ipfix-tcpo-v6eh-05-intdir-early-von-hugo-2024-01-13/

and IPFIX doctor
https://mailarchive.ietf.org/arch/msg/opsawg/9UnFDQUdswZSKntevzSVGqZDcMw/

reviews. The feedbackis currently being addressed by the author.

The Transport Area directorate and the IPFIX doctors challenges
the correctness of the tcpOptionsFull data type. Wherever
this should be a new data type unsigned256 or a bitfield type instead of
unsigned according to reduced size encoding defined in
https://www.rfc-editor.org/rfc/rfc7011#section-6.2. The authors therefore
introduced a new unsigned256 data type in
https://datatracker.ietf.org/doc/html/draft-ietf-opsawg-ipfix-tcpo-v6eh-08#name-new-ipfix-information-element
and a consensus,
https://mailarchive.ietf.org/arch/msg/opsawg/YbOuevvacJ0hwKRjPGaSaMVXRgk/,
has been achieved.

6. Describe how the document meets any required formal expert review criteria,
  such as the MIB Doctor, YANG Doctor, media type, and URI type reviews.

IPFIX doctor review
https://mailarchive.ietf.org/arch/msg/opsawg/9UnFDQUdswZSKntevzSVGqZDcMw/

Appart of the data type choice for tcpOptionsFull, tcpSharedOptionExID16 and
tcpSharedOptionExID32 there are other remarks about justifications
why new IPFIX entities have been introduced.

7. If the document contains a YANG module, has the final version of the module
  been checked with any of the [recommended validation tools][4] for syntax and
  formatting validation? If there are any resulting errors or warnings, what is
  the justification for not fixing them at this time? Does the YANG module
  comply with the Network Management Datastore Architecture (NMDA) as specified
  in [RFC 8342][5]?

N/A

8. Describe reviews and automated checks performed to validate sections of the
  final version of the document written in a formal language, such as XML code,
  BNF rules, MIB definitions, CBOR's CDDL, etc.

N/A (other than IDNITS)

## Document Shepherd Checks

9. Based on the shepherd's review of the document, is it their opinion that this
  document is needed, clearly written, complete, correctly designed, and ready
  to be handed off to the responsible Area Director?

Once the open points by the IPFIX doctor and the data type choices have been resolved,
yes it is. I have reviewed the document and had minor comments.

10. Several IETF Areas have assembled [lists of common issues that their
    reviewers encounter][6]. For which areas have such issues been identified
    and addressed? For which does this still need to happen in subsequent
    reviews?

Transport, OPS, Internet area and IPFIX doctors have reviewed. I do not believe detailed
subsequent reviews are required.

11. What type of RFC publication is being requested on the IETF stream ([Best
    Current Practice][12], [Proposed Standard, Internet Standard][13],
    [Informational, Experimental or Historic][14])? Why is this the proper type
    of RFC? Do all Datatracker state attributes correctly reflect this intent?

Proposed Standard is being requested for new IPFIX entities according to
https://datatracker.ietf.org/doc/html/rfc7011#section-13, while waiting for more implementations and operational experience.

12. Have reasonable efforts been made to remind all authors of the intellectual
    property rights (IPR) disclosure obligations described in [BCP 79][7]? To
    the best of your knowledge, have all required disclosures been filed? If
    not, explain why. If yes, summarize any relevant discussion, including links
    to publicly-available messages when applicable.

A poll was sent to the list. The named authors has replied that there is no IPR.

13. Has each author, editor, and contributor shown their willingness to be
    listed as such? If the total number of authors and editors on the front page
    is greater than five, please provide a justification.

Yes

14. Document any remaining I-D nits in this document. Simply running the [idnits
    tool][8] is not enough; please review the ["Content Guidelines" on
    authors.ietf.org][15]. (Also note that the current idnits tool generates
    some incorrect warnings; a rewrite is underway.)

None found

15. Should any informative references be normative or vice-versa? See the [IESG
    Statement on Normative and Informative References][16].

No

16. List any normative references that are not freely available to anyone. Did
    the community have sufficient access to review any such normative
    references?

N/A

17. Are there any normative downward references (see [RFC 3967][9] and [BCP
    97
][10]) that are not already listed in the [DOWNREF registry][17]? If so,
    list them.

No

18. Are there normative references to documents that are not ready to be
    submitted to the IESG for publication or are otherwise in an unclear state?
    If so, what is the plan for their completion?

No

19. Will publication of this document change the status of any existing RFCs? If
    so, does the Datatracker metadata correctly reflect this and are those RFCs
    listed on the title page, in the abstract, and discussed in the
    introduction? If not, explain why and point to the part of the document
    where the relationship of this document to these other RFCs is discussed.

No

20. 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 aspects of the document requiring IANA assignments are
    associated with the appropriate reservations in IANA registries. Confirm
    that any referenced IANA registries have been clearly identified. Confirm
    that each newly created IANA registry specifies its initial contents,
    allocations procedures, and a reasonable name (see [RFC 8126][11]).

The IPFIX entities created by this document are consistent with the body of the
document. IPFIX entities are added to the existing registry as defined in
https://datatracker.ietf.org/doc/html/rfc7012#section-7.4.

21. List any new IANA registries that require Designated Expert Review for
    future allocations. Are the instructions to the Designated Expert clear?
    Please include suggestions of designated experts, if appropriate.

This document defines new IPFIX entities for IPv6 extension headers and TCP
options and a new IPFIX data type. The working group is not aware of any existing
or planned implementations. IPFIX entity 64 ipv6ExtensionHeaders has been
adopted widely. Where IPFIX entity 209 tcpOptions appears to be,

reviews. The feedbackis currently being addressed by the author.

The Transport Area directorate and the IPFIX doctors challenges
the correctness of the tcpOptionsFull data type. Wherever
this should be a new data type unsigned256 or a bitfield type instead of
unsigned according to reduced size encoding defined in
https://www.rfc-editor.org/rfc/rfc7011#section-6.2. The authors therefore
introduced a new unsigned256 data type in
https://datatracker.ietf.org/doc/html/draft-ietf-opsawg-ipfix-tcpo-v6eh-08#name-new-ipfix-information-element
and a consensus,

Appart of the data type choice for tcpOptionsFull, tcpSharedOptionExID16 and

why new IPFIX entities have been introduced.

7. If the document contains a YANG module, has the final version of the module
  been checked with any of the [recommended validation tools][4] for syntax and

## Document Shepherd Checks

9. Based on the shepherd's review of the document, is it their opinion that this
  document is needed, clearly written, complete, correctly designed, and ready
  to be handed off to the responsible Area Director?

Once the open points by the IPFIX doctor and the data type choices have been resolved,
yes it is. I have reviewed the document and had minor comments.

10. Several IETF Areas have assembled [lists of common issues that their
    reviewers encounter][6]. For which areas have such issues been identified
    and addressed? For which does this still need to happen in subsequent
    reviews?

Transport, OPS, Internet area and IPFIX doctors have reviewed. I do not believe detailed
subsequent reviews are required.

11. What type of RFC publication is being requested on the IETF stream ([Best
    Current Practice][12], [Proposed Standard, Internet Standard][13],
    [Informational, Experimental or Historic][14])? Why is this the proper type
    of RFC? Do all Datatracker state attributes correctly reflect this intent?

Proposed Standard is being requested for new IPFIX entities according to
https://datatracker.ietf.org/doc/html/rfc7011#section-13, while waiting for more implementations and operational experience.

12. Have reasonable efforts been made to remind all authors of the intellectual
    property rights (IPR) disclosure obligations described in [BCP 79][7]? To
    the best of your knowledge, have all required disclosures been filed? If
    not, explain why. If yes, summarize any relevant discussion, including links
    to publicly-available messages when applicable.

A poll was sent to the list. The named authors has replied that there is no IPR.

13. Has each author, editor, and contributor shown their willingness to be
    listed as such? If the total number of authors and editors on the front page
    is greater than five, please provide a justification.

Yes

14. Document any remaining I-D nits in this document. Simply running the [idnits
    tool][8] is not enough; please review the ["Content Guidelines" on
    authors.ietf.org][15]. (Also note that the current idnits tool generates
    some incorrect warnings; a rewrite is underway.)

None found

15. Should any informative references be normative or vice-versa? See the [IESG
    Statement on Normative and Informative References][16].

No

16. List any normative references that are not freely available to anyone. Did
    the community have sufficient access to review any such normative
    references?

N/A

17. Are there any normative downward references (see [RFC 3967][9] and [BCP
    97
][10]) that are not already listed in the [DOWNREF registry][17]? If so,
    list them.

No

18. Are there normative references to documents that are not ready to be
    submitted to the IESG for publication or are otherwise in an unclear state?
    If so, what is the plan for their completion?

No

19. Will publication of this document change the status of any existing RFCs? If
    so, does the Datatracker metadata correctly reflect this and are those RFCs
    listed on the title page, in the abstract, and discussed in the
    introduction? If not, explain why and point to the part of the document
    where the relationship of this document to these other RFCs is discussed.

No

20. 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 aspects of the document requiring IANA assignments are
    associated with the appropriate reservations in IANA registries. Confirm
    that any referenced IANA registries have been clearly identified. Confirm
    that each newly created IANA registry specifies its initial contents,
    allocations procedures, and a reasonable name (see [RFC 8126][11]).

The IPFIX entities created by this document are consistent with the body of the
document. IPFIX entities are added to the existing registry as defined in
https://datatracker.ietf.org/doc/html/rfc7012#section-7.4.

21. List any new IANA registries that require Designated Expert Review for
    future allocations. Are the instructions to the Designated Expert clear?
    Please include suggestions of designated experts, if appropriate.

# Document Shepherd Write-Up for Group Documents

*This version is dated 10 February 2024.*

Thank you for your service as a document shepherd. Among the responsibilities is
answering the questions in this write-up to give helpful context to Last Call
and Internet Engineering Steering Group ([IESG][1]) reviewers, and your
diligence in completing it is appreciated. The full role of the shepherd is
further described in [RFC 4858][2]. You will need the cooperation of the authors
and editors to complete these checks.

Note that some numbered items contain multiple related questions; please be sure
to answer all of them.

## Document History

1. Does the working group (WG) consensus represent the strong concurrence of a
  few individuals, with others being silent, or did it reach broad agreement?

Within the working group, this document was seen as valuable since it addresses
current limitations of IPFIX entity 209 tcpOptions and 64 ipv6ExtensionHeaders.
OPSAWG reached consensus to deprecate ipv6ExtensionHeaders and tcpOptions as
described in section 8.1 and in introduce new IPFIX entities. Section 8.2
introduces a new IPFIX data type since existing unsigned integers were to small.

2. Was there controversy about particular points, or were there decisions where
  the consensus was particularly rough?

Consesus was achieved without any opposing voice.

3. Has anyone threatened an appeal or otherwise indicated extreme discontent? If
  so, please summarize 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

4. For protocol documents, are there existing implementations of the contents of
  the document? Have a significant number of potential implementers indicated
  plans to implement? Are any existing implementations reported somewhere,
  either in the document itself (as [RFC 7942][3] recommends) or elsewhere
  (where)?

This document defines new IPFIX entities for IPv6 extension headers and TCP

# Document Shepherd Write-Up for Group Documents

*This version is dated 4 July 2022.*

Thank you for your service as a document shepherd. Among the responsibilities is
answering the questions in this write-up to give helpful context to Last Call
and Internet Engineering Steering Group ([IESG][1]) reviewers, and your
diligence in completing it is appreciated. The full role of the shepherd is
further described in [RFC 4858][2]. You will need the cooperation of the authors
and editors to complete these checks.

Note that some numbered items contain multiple related questions; please be sure
to answer all of them.

## Document History

1. Does the working group (WG) consensus represent the strong concurrence of a
  few individuals, with others being silent, or did it reach broad agreement?

Within the working group, this document was seen as valuable since it addresses
current limitations of IPFIX entity 209 tcpOptions and 64 ipv6ExtensionHeaders.
Some of the fixes could be applied to the current IPFIX entities with
draft-ietf-opsawg-ipfix-fixes, other issues required new IPFIX entities which
this document addresses. Section 8.2 introduces a new IPFIX data type since
existing unsigned integers were to small.

2. Was there controversy about particular points, or were there decisions where
  the consensus was particularly rough?

Consesus was achieved without any opposing voice.

3. Has anyone threatened an appeal or otherwise indicated extreme discontent? If
  so, please summarize 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

4. For protocol documents, are there existing implementations of the contents of
  the document? Have a significant number of potential implementers indicated
  plans to implement? Are any existing implementations reported somewhere,
  either in the document itself (as [RFC 7942][3] recommends) or elsewhere
  (where)?

This document defines new IPFIX entities for IPv6 extension headers and TCP
options and a new IPFIX data type. The working group is not aware of any existing
or planned implementations. IPFIX entity 64 ipv6ExtensionHeaders has been
adopted widely. Where IPFIX entity 209 tcpOptions appears to be,
https://mailarchive.ietf.org/arch/msg/opsawg/gaJ9-A6i3Z4grgHT86OUym_DAqA/,
merly used to its ambiguity and suggested to deprecate. It is expected that the
IPFIX entities defined in this document are going to be implemented.

## Additional Reviews

5. Do the contents of this document closely interact with technologies in other
  IETF working groups or external organizations, and would it therefore benefit
  from their review? Have those reviews occurred? If yes, describe which
  reviews took place.

Yes, the document received

Transport area
https://datatracker.ietf.org/doc/review-ietf-opsawg-ipfix-tcpo-v6eh-05-tsvart-early-eddy-2024-01-02/

and IPFIX doctor
https://mailarchive.ietf.org/arch/msg/opsawg/9UnFDQUdswZSKntevzSVGqZDcMw/

reviews. The feedbackis currently being addressed by the author.

The Transport Area directorate and the IPFIX doctors challenges
the correctness of the tcpOptionsFull data type. Wherever
this should be a new data type unsigned256 or a bitfield type instead of
unsigned according to reduced size encoding defined in
https://www.rfc-editor.org/rfc/rfc7011#section-6.2. The authors therefore
introduced a new unsigned256 data type in
https://datatracker.ietf.org/doc/html/draft-ietf-opsawg-ipfix-tcpo-v6eh-08#name-new-ipfix-information-element
and a consensus, https://mailarchive.ietf.org/arch/msg/opsawg/wqP_V-UAn7-o0SQ4bbUCyeHeHCA/,
is pending wherever this is the best choice.

6. Describe how the document meets any required formal expert review criteria,
  such as the MIB Doctor, YANG Doctor, media type, and URI type reviews.

IPFIX doctor review
https://mailarchive.ietf.org/arch/msg/opsawg/9UnFDQUdswZSKntevzSVGqZDcMw/

Appart of the data type choice for tcpOptionsFull, tcpSharedOptionExID16 and
tcpSharedOptionExID32 there are other remarks about justifications
why new IPFIX entities have been introduced.

7. If the document contains a YANG module, has the final version of the module
  been checked with any of the [recommended validation tools][4] for syntax and
  formatting validation? If there are any resulting errors or warnings, what is
  the justification for not fixing them at this time? Does the YANG module
  comply with the Network Management Datastore Architecture (NMDA) as specified
  in [RFC 8342][5]?

N/A

8. Describe reviews and automated checks performed to validate sections of the
  final version of the document written in a formal language, such as XML code,
  BNF rules, MIB definitions, CBOR's CDDL, etc.

N/A (other than IDNITS)

## Document Shepherd Checks

9. Based on the shepherd's review of the document, is it their opinion that this
  document is needed, clearly written, complete, correctly designed, and ready
  to be handed off to the responsible Area Director?

Once the open points by the IPFIX doctor and the data type choices have been resolved,
yes it is. I have reviewed the document and had minor comments.

10. Several IETF Areas have assembled [lists of common issues that their
    reviewers encounter][6]. For which areas have such issues been identified
    and addressed? For which does this still need to happen in subsequent
    reviews?

Transport, OPS, Internet area and IPFIX doctors have reviewed. I do not believe detailed
subsequent reviews are required.

11. What type of RFC publication is being requested on the IETF stream ([Best
    Current Practice][12], [Proposed Standard, Internet Standard][13],
    [Informational, Experimental or Historic][14])? Why is this the proper type
    of RFC? Do all Datatracker state attributes correctly reflect this intent?

Internet Standard is being requested for new IPFIX entities according to
https://datatracker.ietf.org/doc/html/rfc7011#section-13

12. Have reasonable efforts been made to remind all authors of the intellectual
    property rights (IPR) disclosure obligations described in [BCP 79][7]? To
    the best of your knowledge, have all required disclosures been filed? If
    not, explain why. If yes, summarize any relevant discussion, including links
    to publicly-available messages when applicable.

A poll was sent to the list. The named authors has replied that there is no IPR.

13. Has each author, editor, and contributor shown their willingness to be
    listed as such? If the total number of authors and editors on the front page
    is greater than five, please provide a justification.

Yes

14. Document any remaining I-D nits in this document. Simply running the [idnits
    tool][8] is not enough; please review the ["Content Guidelines" on
    authors.ietf.org][15]. (Also note that the current idnits tool generates
    some incorrect warnings; a rewrite is underway.)

None found

15. Should any informative references be normative or vice-versa? See the [IESG
    Statement on Normative and Informative References][16].

No

16. List any normative references that are not freely available to anyone. Did
    the community have sufficient access to review any such normative
    references?

N/A

17. Are there any normative downward references (see [RFC 3967][9] and [BCP
    97
][10]) that are not already listed in the [DOWNREF registry][17]? If so,
    list them.

No

18. Are there normative references to documents that are not ready to be
    submitted to the IESG for publication or are otherwise in an unclear state?
    If so, what is the plan for their completion?

No

19. Will publication of this document change the status of any existing RFCs? If
    so, does the Datatracker metadata correctly reflect this and are those RFCs
    listed on the title page, in the abstract, and discussed in the
    introduction? If not, explain why and point to the part of the document
    where the relationship of this document to these other RFCs is discussed.

No

20. 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 aspects of the document requiring IANA assignments are
    associated with the appropriate reservations in IANA registries. Confirm
    that any referenced IANA registries have been clearly identified. Confirm
    that each newly created IANA registry specifies its initial contents,
    allocations procedures, and a reasonable name (see [RFC 8126][11]).

The IPFIX entities created by this document are consistent with the body of the
document. IPFIX entities are added to the existing registry as defined in
https://datatracker.ietf.org/doc/html/rfc7012#section-7.4.

21. List any new IANA registries that require Designated Expert Review for
    future allocations. Are the instructions to the Designated Expert clear?
    Please include suggestions of designated experts, if appropriate.
