IEEE 802.1 Working Group

May 13-17, 2024 Interim Session

Warsaw, Poland – 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.

7 Nendica

Between this session and the preceding session, the IEEE 802 “Network Enhancements for the Next Decade” Industry Connections Activity (Nendica) held electronic meetings whose minutes are incorporated to these session minutes by reference as follows:

Call to order May 16, 2024 8:05 CEST by Johannes Specht, Nendica Vice Chair (“Chair”), who presided. Jessy Rouyer, IEEE 802.1 Recording Secretary, wrote the minutes.

Agenda items and dispositions:

1. Meeting introduction and other administrative items. The IEEE SA slides on IEEE Patent Policy, IEEE SA Copyright Policy, and Participant Behavior (“Policies”) were provided beforehand as part of “MEETING INTRODUCTION” https://www.ieee802.org/1/files/public/templates/admin-prePAR-intro-0324-v01.pdf. The Chair showed this presentation advising that the following applies:

  • Participant behavior shall comply with the outlined requirements;
  • 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 the Nendica meeting, whether verbal, recorded, or in written form, is a Contribution and shall comply with the IEEE SA Copyright Policy.

The 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 Chair presented the agenda at https://1.ieee802.org/802-nendica-agenda-2024-05-16/ and noted the Mentor server document list.

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

3. Minutes. The Chair reviewed the draft “Minutes of the Nendica meeting held 2024-05-02 09:00-11:00 ET” https://listserv.ieee.org/cgi-bin/wa?A2=STDS-802-1-MINUTES;7638db58.24&S=

Disposition: Agreed (informally, none dissenting) to approve the minutes.

4. Update. No discussion.

5. Nendica organization. No discussion.

6. Study Items.

AI Computing Networks (AICN). Yunping(Lily) Lyu and Jieyu Li presented “AICN Report Draft v0” https://mentor.ieee.org/802.1/dcn/24/1-24-0028-00-ICne-aicn-report-draft.pdf.

Discussion: It was suggested that references be provided for numerical values currently provided as is. Deadlocks, priority-based flow control, and the comparative pros and cons of lossless techniques (in large scale networks) vs. best effort techniques (elsewhere) in meeting AI requirements were discussed. It was suggested that a new transport paradigm may be needed for best effort delivery in such networks where not all flows require ordered delivery (remote direct memory access example), and not all applications require scale. It was indicated that the current draft may address a subset of AI applications at larger scale only, and that there may be a broader range of AI applications at different scales. Contribution suggested. It was indicated that “100s GB” in the table on page 8 is for one iteration. It was suggested to change “40,000 kW” to “40 MW” and to delete “, which could power around 31,000 average U.S. homes[3].” in the last paragraph on page 9.

Disposition: Contributions were invited. More discussion needed. Post-session presentation update: https://mentor.ieee.org/802.1/dcn/24/1-24-0028-01-ICne-aicn-report-draft.pdf.

7. Vetting and New Topics. No discussion.

8. Next Meeting. Nendica is authorized to meet electronically alternate Thursdays 9:00 – 11:00 ET with additional meetings as announced at least 10 days in advance. Nendica intends to meet next electronically on May 30, 2024 9:00 – 11:00 ET (may be cancelled two days prior in absence of contributions).

9. Other Business. No other business was discussed by Nendica in this session.

Disposition: For information.

4. YANGsanity Spreadsheet. The YANGsters Chair presented slide 3 of the presentation in agenda item 3.

  • The slide’s YANG “sanity” table provides an overview of all currently open IEEE 802.1 projects that contain or are expected to contain YANG.

Disposition: For information.

The YANGsters Chair presented “Link Aggregation YANG Considerations” https://www.ieee802.org/1/files/public/docs2024/yangsters-smansfield-axdz-augmentation-issue-0524-v01.pdf to introduce the topic and led the discussion. – The current structure of the P802.1AXdz YANG is such that there is an issue if a port is an aggregation port.

  • To address this issue there is a need to update the ieee802-dot1q-bridge.yang module so that it allows the bridge-port container to be excluded from the tree when an ethernetCSMAcd is an aggregation port.
  • Several options to achieve this were discussed.

Disposition: More discussion needed.
