IEEE 802.1 Working Group

September 16-20, 2024 Interim Session

Hamburg, Germany – Mixed Mode

Session Minutes

The Working Group (WG) Chair, Glenn Parsons, presided and had requested that any subgroup Chair in remote attendance have on-site an individual acting on their behalf as needed to help conduct proceedings in “mixed mode”, i.e. with local and remote participants.

The Recording Secretary, Jessy Rouyer, wrote and/or edited the minutes in part based on input from subgroup Chairs and their Secretaries.

Note that, throughout this document, minuted/recorded inputs from any attendee can not/shall not be assumed to represent a position of their employer or affiliated organization. Discussion points captured do not necessarily reflect the views of the presenter, discussion leader or minute taker, and do not imply consensus unless that is explicitly minuted. The content of draft standards is determined by the ballot process; other formal decisions are the subject of Working Group motions.

See section 1 for attendance and affiliation information.

Call to order Sep 18, 2024 at 08:00 CEST by Mick Seaman, IEEE 802.1 Security 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” https://www.ieee802.org/1/files/public/templates/admin-TG-intro-0324-v01.pdf.

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

  • Participant behavior shall comply with the outlined requirements;
  • 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 SAs 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 Security TG Chair made the Call for Potentially Essential Patents 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 this Call prior to the end of the session.

3.1. Draft development. Mick Seaman presented “PFC Management” https://www.ieee802.org/1/files/public/docs2024/dt-seaman-pfc-management-0924-v02.pdf for discussion.

Discussion:

  • Some (a significant number, though not all) PFC implementations use PFC without DCBX. This possibility is desirable.
  • Some implementations (again a significant proportion) wait for a DCBX indication that a PFC will be acted upon before transmitting PFC to pause a given priority. This can be important to avoid PFC storms.
  • Clarification/specification in areas noted in the presentation is important.

Disposition: Discussion to be continued.

4. A.O.B (Any other business). The Security TG Chair drew attention to “Impact of MACsec on Ethernet traffic latency and PTP timestamping accuracy” https://www.ieee802.org/1/files/public/docs2024/new-parkholm-MACsec-impact-on-latency-and-PTP-timestamping-0924-v01.pdf.

Discussed new non-ballot comment #164.

Disposition: Proposed comment resolution for non-ballot comment #164 updated.

7. Richard Tse presented “Individual Contirbution: Fault-Tolerant Timing with Time Integrity” https://www.ieee802.org/1/files/public/docs2024/ed-tse-draft-text-contribution-0924-v01.pdf

Discussion: Discussed open questions related to end stations shown in Figure 1 as it could be one receiver or more, the definition of the FTTM and its implementation since FTTM represents a function and not a specific implementation, the procedure for detecting a loss of synchronization on one of the clock sources, the local oscillator independency from the lock clocks of the PTP instances, and the mixing of the physical stations with FFTM function that could be implemented across different physical elements.

Disposition: For information.

8. Daniel Finnegan presented “Fault-Tolerant Grandmaster Clock Synchronization Needs for Highly-Reliable Systems” https://www.ieee802.org/1/files/public/docs2024/ed-finnegan-FT-GM-Sync-0924-v01.pdf.

Discussion: Discussed open questions on certification for MIURA 1 (TSN enabled), the analysis of P802.1DP vs Miura deterministic (e.g. bandwidth, latency and number of hops), synchronisation and network resilience for communication requirements, FTTM use in place of BTCA for robustness but not for integrity. Suggestion to specify topology templates for different types of vehicles. OEM (Monitoring) in TSN (and consequently for P802.1DP) is in its early stage of standardization. Discussed the purpose and consideration of MACsec in Miura and its implication on added maintenance complications (suggestion to share use case for MACsec for Miura). Comment that P802.1DP does not require authentication or MACsec, but it is transparent for these features. The need (or not) for specifying standardized interfaces for synchronization applications to the network and its corresponding GCL schedule. Question on the need for stream isolation and additional frame preemption. Suggestion to propose required changes (by submitting ballot comments) to facilitate certifications.

Disposition: More discussion needed.
