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 acting 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 acting 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.

Call to order Sep 14, 2022 at 10:30 ET by Mick Seaman, IEEE 802.1 Security TG Chair, who presided and wrote the minutes assisted by Karen Randall, Security TG Vice-Chair.

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

  • IEEEs 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.

3. P802.1AEdk MAC Privacy protection. The Security TG Chair reminded the meeting that P802.1AEdk MAC Privacy protection is out for SA ballot, closing Sep 20, 2022.

4. P802.1Qdt Priority-based Flow Control Enhancements. Lily Lv led a discussion of an initial draft of P802.1Qdt https://www.ieee802.org/1/files/private/dt-drafts/d0/802-1Qdt-d0-0.pdf.

Discussion:

  • Reviewed Clauses 1 through 5.
  • May need reference to IEEE 1588, check for explicit/normative references in the text.
  • 1588 referenced for medium delay as part of headroom calculation. Very difficult aspect of the project.
  • May not need ultra-precise timestamp. Do we need statement about accuracy?
  • PFC preemption may lower headroom. PFC frames not envisaged as express frames.
  • 12:30 -13:30 ET recess
  • Adaptive headroom calculation. What is actually required is knowledge of the maximum amount of data that will be received after the decision to send a PFC has been made. This includes data that the remote system has already transmitted and is “in flight” at that decision time plus data sent during the time from decision time to PFC transmit plus PFC transmit delay, PFC recognition and processing by the remote system, and time to halt transmission. This is effectively the “round trip” from the receiving systems PFC transmitter back to the receiving system’s reception of data controlled by the PFC. It is actually independent of delay symmetry on the physical communication medium.
  • The “round trip delay” is a better measure of the headroom as it avoids the need to add in a worst-case estimate of the internal transmission and processing delays in the remote system and its peer. A ping type protocol from PFC transmitter to a queue controlling entity should provide a fair measurement of the round trip, assuming that the time taken by the remote system to respond is close to the time that system would take to halt transmission of the PFC-affected traffic. DCBX (or the measurement protocol) could carry an adjustment parameter if the remote system knows an adjustment should be made. The PFC originator can make its own adjustment as necessary.
  • The “round trip delay measurement” would naturally account for any additional internal delays, such as the use of MACsec to protect the PFC frames themselves. The measurement should use the same protection (or lack of it) as the PFC (in one direction) and the data in the other.
  • MACsec enabled PFC frame transmission desirable to reduce potential for disruption.
  • MACsec Privacy protection on PFCs probably not required. Timeliness would (in almost all cases) require transmission as Individual Privacy Frames (not in a Privacy Channel) to minimize headroom. Some adjustment of frame size could therefore be provided, which might provide a degree of obscurity if other traffic is being conveyed in Individual Privacy Frames. The problem is that the observable presence of PFC frames can reveal the fact that a large amount of real traffic is being carried, or that the priority mix of traffic has changed. Target environments for PFC may not be that sensitive.
  • Plan a new presentation to the TSN TG to discuss headroom timing options again. Recommended to be more “Here’s what we think we should do” (round trip measurement) rather than a restart.
  • Clause 38 DCBX. Goal statement needs modification.
  • Clause 48 YANG Data model. Security considerations primarily concerned with denial of service. List the read-write objects.
  • Annex D TLV Definitions.

Disposition: Next steps: work on overview required. Presentation to the TSN TG on round-trip measurement for headroom calculation. UML for management variables (concise one-page view). Security TG to review P802.1Qdt/D0.2 https://www.ieee802.org/1/files/private/dt-drafts/d0/802-1Qdt-d0-2.pdf

5. A.O.B (Any other business). No other business at this meeting.

6. Future meetings. The Security TG will not meet at the Nov 2022 plenary session in Bangkok, Thailand. Electronic meetings will be held separately to address the following topics:

  • P802.1AEdk SA ballot resolution.
  • P802.1Qdt status updates and a presentation on headroom timing for the TSN TG.
  • Continued discussion on the BBF liaison re: 802.1X YANG.
