Disposition: Check informally with 802.11 members who have participated in past 802.1 Security TG discussions. Decide how to proceed in the March 2021 plenary session.

7. P802.1AEdk MAC Privacy protection – Draft development (cont.). Don Fedyk, P802.1AEdk Editor, presented “MAC Privacy Maximum Latency”

https://www.ieee802.org/1/files/public/docs2021/dk-fedyk-dot1aedk-maximum-latency-0121-v00.pdf.

Mick Seaman continued the presentation of “Transmit selection and traffic shaping for Privacy Channels”

https://www.ieee802.org/1/files/public/docs2021/dk-seaman-txselection-and-shaping-0121-v00.pdf.

Discussion:

How do Privacy Channels work with existing transmission shaping and selection algorithms: strict priority, credit-based shaper, ETS, ATS and enhancements for scheduled traffic (transmission gates).

An easy combination with strict/simple priority.

Noted transmission gates are used in P802.1Qcz.

Assume all traffic in a Privacy Channel is subject to the same transmission selection algorithm. Otherwise too complicated.

ATS with higher priority in individual Privacy Frames is the simplest way of maintaining bounded per hop latency.

For progressing Clause 20, look at/expand the functional blocks in Figure 20-1.

Disposition: For further discussion.

8. MACsec performance requirements. Rich Dubrawski presented “802.1AE-2018 SecY Delay” https://www.ieee802.org/1/files/public/docs2021/ae-dubrawski-secy-delay-0121-v00.pdf.

Discussion:

Original performance parameters were from 2004 work.

Need to cover speeds to 400 Gb/s.

Packet data should not be revealed externally until ICV has been checked. Can result in additional component delay as checked packet is moved from constrained checking scope (system architecture dependent) and move time can be important at very high speed.

Some knowledge of component delay is a factor in overall system delay, some bounds needed.

At 1G and 10G (some) implementation focus has been more on variability/jitter than absolute delay as minimizing jitter is TSN friendly (particularly when supporting 802.1AS PTP).

Worth consulting IEEE 802.1BA (see page 15).

Disposition: Anticipate future work.

15:18 ET recess

Call to order Jan 20, 2021 at 13:30 ET by Mick Seaman, IEEE 802.1 Security TG Chair.

9. P802.1AEdk MAC Privacy protection – Draft development (cont.). The Security TG Chair led a discussion of the next steps in the development of the draft.

Discussion:

Further development/drafting of text for Clause 20 PrY Operation, as a foundation for drafting Clause 5 Conformance, taking into account the discussion during this meeting.

Disposition:  Anticipated review of updated Clause 20 text in the next Security TG electronic meeting and the March 2021 plenary session.

10. Any Other Business. No other business was discussed by the Security TG in this session.

11. Future meetings. A Security TG electronic meeting will be scheduled for Feb 16, 2021 13:00 ET.

11:23 ET adjournment

The table in section 1 reflects, for all meetings held in this session, the attendance and affiliation of participants who registered their attendance in IMAT.

Call to order Jan 18, 2021 at 9:00 ET by Ludwig Winkel, IEC 65C/WG18 Convenor and IEC/IEEE 60802 Joint Project Chair (60802 Chair), who presided with János Farkas, IEEE 802.1 TSN TG Chair (TG Chair). Josef Dorr, IEC/IEEE 60802 Joint Project Secretary (60802 Secretary), wrote the minutes.

Agenda items and dispositions:

1. Meeting introduction and other administrative items. The TG Chair showed:

The IEEE SA Copyright Policy slides,

The IEEE SA PatCom Patent Slides for Standards Development Meetings,

The IEEE SA slides regarding IEEE Codes of Ethics and Conduct, participation in the “individual process”, and dominance,

The decorum information, and

The reminder for participants to register their attendance in IMAT

contained in “MEETING INTRODUCTION” http://www.ieee802.org/1/files/public/templates/admin-WG+TG-intro-0720-v01.pdf thereby providing the information on slides 2 and 5 of this presentation, and made the Call for Potentially Essential Patents: there were no responses to these Calls prior to the end of the session. The 60802 Chair explained that the IEC/IEEE 60802 Joint Project also follows the usual IEC patent https://www.iec.ch/members_experts/tools/patents/patent_policy.htm and copyright https://www.iec.ch/standardsdev/resources/draftingpublications/overview/rules_requirements/copyright.htm policies.

2. Approval of agenda. The 60802 Chair presented the agenda in https://1.ieee802.org/2021-01-interim-tsn-agenda/#TSN_8211_IECIEEE_60802.

Disposition: The agenda was reviewed, discussed, and agreed (informally, none dissenting) as presented.

3. Update on the IEC 61802 conformity assessment project. The 60802 Chair gave a verbal update on the IEC 61802 conformity assessment project. Four consortia are involved to sponsor an author; another consortium is interested to become a sponsor by contributions. Two author candidates are considered.

Disposition: For information.

4. Incoming liaison P2971 & P2972. The TG Chair presented the incoming liaison in https://www.ieee802.org/1/files/private/liaisons/liaison-IEEE_P2971+P2972_introduction-0121.pdf.

  • The 60802 Chair explained that IEEE P2971 and IEEE P2972 are proposed by the IEEE Computer Society Smart Manufacturing Standards Committee (IEEE C/SM SC: https://sagroups.ieee.org/smsc/), chaired by Sha Wei, with proposed titles as follows:

P2971 “Standard for Test Requirements and Methods for Time Sensitive Networking Gateway in the Field of Industrial Internet of Things”.

P2972 “Standard for General Requirements of Gateway Supporting Time Sensitive Networking in Factory Environments”.

  • The P2971 PAR is approved and the P2972 PAR is on the Jan 26, 2021 NesCom agenda.
  • Both projects are proposed to be organized under Working Groups following the entity process. Participation in these projects is thus on an entity rather than individual basis.
  • Only a few other projects are in this new SM Standards Committee: P2934 (Standard for Logistics Operation Process in a Smart Factory), P2959 (Standard for Technical Requirements of Standard-Oriented Knowledge Graphs), P2671 (Standard for General Requirements of Online Detection Based on Machine Vision in Intelligent Manufacturing), and P2806 (System Architecture of Digital Representation for Physical Objects in Factory Environments).

Disposition: The IEC/IEEE 60802 Joint Project identified a number of inaccurate statements related to the 60802 project. The industry (and with that, 60802) is focused on converged technology to avoid gateways.

If the P2972 project is approved during the NesCom meeting, then the 60802 Chair can work together with IEEE 802.1 management on “what coordination options” should be considered.

5. Editor’s report. Jordon Woods, 60802 Editor, presented “Editor’s Report 60802 Draft 1.2” https://www.ieee802.org/1/files/public/docs2021/60802-woods-D1-2-update-0121-v03.pdf

Disposition: For information.

6. Contributions to clauses 4.1 and 4.2: clean and redline. Jordon Woods, IEC/IEEE 60802 Editor, showed subclauses 4.1, 4.2 and 4.3 of https://www.ieee802.org/1/files/private/60802-drafts/d1/60802-Steindl-Clause4-0121-v06-clean.pdf and walked through the updated subclauses.

Disposition: More discussion needed. The IEC/IEEE 60802 Editor would rework the document based on the discussion. The reworked document can be discussed in another IEC/IEEE 60802 Joint Project meeting in this interim session.

7. IEC/IEEE 60802 D1.2 TG ballot comment resolution. Jordon Woods, IEC/IEEE 60802 Editor, continued the resolution of comments received on http://www.ieee802.org/1/files/private/60802-drafts/d1/60802-d1-2.pdf.

https://1.ieee802.org/yangsters/,

https://1.ieee802.org/yangsters/yangsters-call-information/,

https://1.ieee802.org/category/yangsters-agenda/, and

https://1.ieee802.org/yangsters/yangsters-guidelines/yangsters-faq/.

Disposition: For information.

4. 802f Update. Marc Holness presented “P802f YANG Data Model for Ethertypes Updates” https://www.ieee802.org/1/files/public/docs2021/802f-mholness-Updatel-0121-v03.pdf.

The background on the topic was provided.

Regular meetings are held with the RAC to resolve outstanding issues.

The current proposal under discussion includes:

Introducing four new fields in the Ethertype Public Listing called “friendly name”, “short description”, “last updated”, and “entity tag (SDO/SIG)”.

Adding enhancements to the Ethertype Public Listing’s search to provide a more flexible and robust search.

Clarifying how the new fields are managed.

Input on the topic can be sent to the YANGsters list and 802.1 Chair.

Disposition: For information.

5. YANG Instance Examples. The YANGsters Chair presented https://1.ieee802.org/yangsters/yang-instance-examples/.

The information at https://1.ieee802.org/yangsters/yang-instance-examples/ provides instance examples and guidance on how to use them in YANG related tools to verify YANG modules.

A requ per est was made for those knowledgeable in the art to provide comments.

Disposition: For information.

6. Meta-Data Review. The YANGsters Chair presented https://1.ieee802.org/yangsters/yang-metadata/.

As of Jan 21, 2021, 20 out of 39 files in the published tree of the YANG catalog GitHub repository are missing current metadata.

Four of the modules missing current metadata belong to IEEE 802.1.

Disposition: agreed (informally, none dissenting) that metadata needs to be added to the IEEE 802.1 YANG modules that are missing it.

7. IEEE 802.1Q YANG discussion. Johannes Specht presented https://www.ieee802.org/1/files/public/docs2021/maint-specht-yang-comments-0121-v02.pdf.

The document provided is an update to a previous contribution on the topic.

It includes color coding to indicate how the issues can potentially be handled (i.e. as smaller standalone corrections or as part of a larger remodeling effort of the bridge YANG module).

To progress maintenance item 0242 (https://www.802-1.org/items/357) a decision is required on the approach that would be taken to handle the issues pointed out.

It was pointed out that doing smaller standalone corrections for easy but relevant issues can be done, even if a larger remodeling of the modules is chosen as the long-term solution approach.

The following provide information on how this can be done in a backward compatible way: https://tools.ietf.org/html/draft-ietf-netmod-yang-solutions-01, https://tools.ietf.org/html/draft-ietf-netmod-yang-module-versioning-01, and https://tools.ietf.org/html/draft-ietf-netmod-yang-module-versioning-01.

Disposition: agreed (informally, none dissenting) that more discussion on how to proceed with the aforementioned maintenance item is required.

8. IETF VLAN Comments. The YANGsters chair presented “Sub-interface VLAN YANG Data Models” https://www.ietf.org/archive/id/draft-ietf-netmod-sub-intf-vlan-model-07.txt.

A request was made in a previous YANGsters electronic meeting for those knowledgeable in the art to provide comments (as individuals) to help ensure the sub-interface information is accurate. This request was repeated.

Disposition: For information.

9. YANG Doctors Question. The YANGsters Chair presented the maintenance item at https://www.802-1.org/items/420/requests/310/pre.

An email with questions on this maintenance item was sent to the YANG doctors.

The request on feedback from the YANG doctors will be sent again.

Disposition: For information

10. The YANGsters Chair led the discussion on “Guidelines for discussion”.

Questions on guidelines and best practices to draft IEEE 802.1 YANG modules have been raised in the past and keep recurring, often in comment resolutions.

The following items have been presented and discussed:

MIB to YANG mapping

RFC 6643 provides information on the mapping from MIB to YANG.

Use of Types file

It was discussed if types defined in YANG modules should be split out into separate types files and under what conditions.

If a type is expected to be used by another module putting the types file in a separate file is a good idea.

If a type is only used within its own module it should be kept in the module itself.

“Don’t invent inheritance, discover it.”

Moving types from one YANG file into a types file at a later point in time can potentially cause issues when importing that type and should be avoided.

If moving a type is required, the type should be kept in the original file and deprecated in addition to moving it.

Guidelines for prefixing

Prefixes should be short but not incomprehensible.

Guidelines should help to have a common approach on module names and prefixes but following them should not be a hard requirement.

Changing the prefixes of existing modules can be done in a backward compatible way (as pointed out in section 11 of RFC 7950).

A discussion of “Style” was deferred by lack of time.

A discussion of “Names and Abbreviations” was deferred by lack of time.

Disposition: Agreed (informally, none dissenting) that guidelines following the discussion on the YANGsters page would be helpful.

11. Update on Hot Issues was deferred by lack of time.

12. Next Calls was deferred by lack of time.

13. Any Other Business. No other business was discussed by YANGsters in this session.

14. Future meetings. Although not discussed, YANGsters meet next during the electronic meeting on Jan 26, 2021.
