Call to order Jan 16, 2023 at 9:06 ET by Paul Congdon, IEEE 802.1 Maintenance TG Chair who presided and wrote the minutes.

Agenda items and dispositions:

1. Meeting introduction. The IEEE SA slides on IEEE Patent Policy and IEEE SA Copyright and Participation Policies were provided beforehand as part of “MEETING INTRODUCTION” http://www.ieee802.org/1/files/public/templates/admin-TG-intro-0721-v01.pdf.

The Maintenance TG Chair showed this presentation advising that the following, provided beforehand, applies:

  • IEEE’s Patent Policy is described in Clause 6 of the IEEE SA Standards Board Bylaws;
  • Early identification of patent claims which may be essential for the use of standards under development is strongly encouraged;
  • There may be Essential Patent Claims of which IEEE is not aware. Additionally, neither IEEE, the WG, nor the WG Chair can ensure the accuracy or completeness of any assurance or whether any such assurance is, in fact, of a Patent Claim that is essential for the use of the standard under development.
  • IEEE SA’s copyright policy is described in Clause 7 of the IEEE SA Standards Board Bylaws and Clause 6.1 of the IEEE SA Standards Board Operations Manual;
  • Any material submitted during standards development, whether verbal, recorded, or in written form, is a Contribution and shall comply with the IEEE SA Copyright Policy.

The Maintenance TG Chair made the Calls for Potentially Essential Patents at the beginning of each TG meeting during this session thereby providing an opportunity for participants to identify patent claim(s)/patent application claim(s) and/or the holder of patent claim(s)/patent application claim(s) of which the participant is personally aware and that may be essential for the use of that standard: there were no responses to these Calls prior to the end of the session.

The Maintenance TG Chair asked participants to record their attendance in IMAT and, if they are unable to do so, to promptly provide their affiliation to the minute taker.

2. Approval of agenda. The Maintenance TG chair presented the agenda in https://1.ieee802.org/january-2023-interim-session-maintenance-tg-agenda/

Disposition: the agenda was reviewed, discussed and updated as recorded by these minutes.

3. P802.1Qdt Priority-based Flow Control Enhancements

3.1 PAR and CSD modification. The 802.1 Working Group closing plenary meeting had agreed that this interim session would draft a PAR and CSD modification to relax the requirement to use PTP timing for basis of headroom determination [see the Security TG minutes for the September 2022 interim session and subsequent meetings for technical rationale]. This meeting would draft updates for review by the TSN TG, prior to pre-submission to the 802 EC for new PARs and PAR changes under the usual 30-day rule.

Lily Lv, P802.1Qdt Editor, presented “Qdt PAR & CSD Modification”

https://www.ieee802.org/1/files/public/docs2023/dt-lv-PAR-CSD-Modification-Suppotive-Material-0123-v01.pdf for discussion.

Disposition: Updates to the PAR and CSD as agreed (informally, none

dissenting) in discussion are captured in the updated presentation https://www.ieee802.org/1/files/public/docs2023/dt-lv-PAR-CSD-Modification-Suppotive-Material-0123-v02.pdf.

The PAR and CSD as updated at the closing of the interim session are recorded in https://www.ieee802.org/1/files/public/docs2023/dt-draft-PAR-modification-0123-v01.pdf and https://www.ieee802.org/1/files/public/docs2023/dt-draft-CSD-modification-0123-v01.pdf.

3.2 Draft development. Lily Lv, P802.1Qdt Editor, presented

https://www.ieee802.org/1/files/public/docs2023/dt-lv-PFC-management-objects-0123-v1.pdf. This presentation described proposed management objects, their organization, and their relationship to proposed state machines for the PFC Pause Receiver and for Headroom Measurement.

Discussion:

  • Important not to let packet formats and perceived encoding efficiencies drive the protocol design.
  • In the general case, any headroom mechanism could be used that measures the delay(s) between reference points and provides an additional compensation factor that accounts for the difference in delay between those reference points and the PFC recognition and data transmission queuing points.

12:28 ET recess

Call to order Jan 18, 2023 at 13:34 ET by the  Security TG Chair, who presided and wrote the minutes.

P802.1Qdt draft development discussion continued:

  • The effort, implementation cost, and purpose of statistic gathering and retention requires careful consideration. For example, networks that use PFC to avoid frame loss will not work well if there is frame loss for other reasons. So counting lost frames for headroom delay measurement is unlikely to yield useful results.

Disposition: Discussion to be continued.

4. P802.1AEdk MAC Privacy protection. Mick Seaman, Security TG Chair, reported on the current state of the SA recirculation ballot. The Security TG had completed review of the ballot comments on https://www.ieee802.org/1/files/private/dk-drafts/d2/802-1AEdk-d2-2.pdf, but the new Disapprove voter with the out of scope comments had been invited to join the meeting should they wish to discuss further.

Disposition: No further discussion in this meeting; however, the voter responded prior to the end of the session withdrawing the comments.

5. Quantum Key Distribution – Potential 802.1X amendment. Mick Seaman presented “802.1X MKA PSKs 1 — out-of-band key distribution”

https://www.ieee802.org/1/files/public/docs2022/x-seaman-psks-1222-v0.pdf

setting out a choice of potential standardization options.

Glenn Parsons, 802.1 Working Group Chair, reported that the ITU had established a Joint Coordination Activity on Quantum Key Distribution Network (JCA-QKDN).

Disposition: Discussion to be continued.

6. 802.1AR Signature Suites for 60802/Industrial Automation. Mick Seaman, 802.1 Security TG Chair, noted that the IEC/IEEE 60802 Joint Project would be discussing 802.1AR Signature Suites in this interim session.

7. BBF Liaison. Mick Seaman, 802.1 Security TG Chair, reported that YANGsters and this TG appeared to be in agreement as to the content of the response to the incoming BBF liaison in https://www.ieee802.org/1/files/public/docs2022/liaison-BBF-1X-YANGmodel-0322.pdf, but a response has not yet been drafted.

Disposition: Response to be created for discussion prior to, and agreement at, the March 2023 802.1 plenary session.

8. A.O.B (Any other business). No other business was discussed at this session.

9. Future meetings. An electronic (Webex) meeting will be held Tuesday Feb 14, 2023 11:00 ET, for P802.1Qdt draft development.

Additional electronic meetings may be held prior to the March 2023 802.1 plenary session to address P802.1Qdt, the BBF liaison, and potential QKD standardization relative to 802.1X.

The Security TG will meet during the March 2023 802 plenary session in Atlanta, GA, USA.

15:00 ET adjournment
