802.1/802.15 Joint Meeting

Call to order Jan 19, 2022 at 11:00 ET by Glenn Parsons, IEEE 802.1 Chair who presided with Pat Kinney, IEEE 802.15 Chair. Jessy Rouyer, IEEE 802.1 Recording Secretary, wrote the minutes.

The table in section 1 reflects the attendance and affiliation of all participants in all 802.1 WG and subgroup meetings held in this session.

Agenda items and dispositions:

1. Meeting introduction and other administrative items.

1.1 Meeting introduction and other administrative items. 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 802.1 Chair showed this presentation implicitly 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 802.1 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 meeting.

The 802.1 Chair asked participants to record their attendance in the 802.1 IMAT or the 802.15 IMAT and, if they are unable to do so, to promptly provide their affiliation to the minute taker.

The 802.1 Chair clarified that 802.1 participants have no registration fee requirement to attend this joint meeting. The 802.15 Chair clarified that 802.15 participants have to register to attend this joint meeting.

1.2 Approval of agenda. The 802.1 Chair presented “Agenda: IEEE 802.1 / 802.15 joint meeting 2022-01-19” https://1.ieee802.org/2022-01-interim-joint-1-15-agenda/

Disposition: The agenda was reviewed, discussed (including a request for Minsoo Kim to present agenda item 2.1 in lieu of Marco Hernandez), and agreed (informally, none dissenting) as reflected by these minutes.

2. 802.15.6.a.

2.1 TSN for wireless 15.6a. Minsoo Kim presented “MAC Bridging for Time-Sensitive Networking of 802.15.6a” https://mentor.ieee.org/802.15/dcn/22/15-22-0024-00-006a-mac-bridging-for-time-sensitive-networking-of-802-15-6a.pptx (updating post-meeting as https://mentor.ieee.org/802.15/dcn/22/15-22-0024-01-006a-mac-bridging-for-time-sensitive-networking-of-802-15-6a.pptx) containing a discussion of MAC Bridging for Time-Sensitive Networking to realize the enhanced reliability of P802.15.6a.

Discussion:

  • Coexistence management as specified in IEC 62657 may be of interest even as IEC 62657 focuses on industrial communication networks rather than wireless BANs that have limited coverage range, frequency allocations, etc.
  • IETF 6LoWPAN work is focused on 802.15.4 (as opposed to 802.15.6a) and focuses on carrying IP over wireless networks that tend to be resource limited: low data rates, no ability to fragment, questionable reliability, etc. There may be applicability beyond 802.15.4 (for example, 6LoWPAN’s IP header compression).
  • TSN concepts (802.1CB and 802.1Qca) may be applicable.

Disposition: Further discussion needed.

3. 802.1 and 802.15 compatibility.

3.1 List of topics. Ben Rolfe presented “List of topics for 802.15/802.1” https://mentor.ieee.org/802.15/dcn/22/15-22-0036-00-0000-list-of-topics-for-802-15-802-1.pptx providing an itemized list summarizing topics for 802.1/802.15 joint effort.

Discussion:

  • The summary questions of slide 4 can help 802.1 help not only 802.15.6a but also 802.11 (regarding Wi-Fi), e.g. by clarifying what the CSD means with respect to being compatible with 802.1AC and 802.1Q: an 802.1 tutorial on this might be helpful.

Disposition: Agreed (informally, none dissenting) to continue discussing the three questions on slide 4 and come back on these at the next joint 802.1/802.15 meeting.

3.2 Bridging Frames with 64-bit Addresses. Roger Marks presented “Bridging Frames with 64-bit Addresses” https://www.ieee802.org/1/files/public/docs2022/cq-marks-64-bit-address-0122.pdf.

Discussion:

  • Suggestion made, referring to slide 7, to allocate an OUI (or CID) that would prefix an EUI-48.
  • End-to-end frame security in 802.15.4 prohibits frame changes however addresses are not encrypted (even as the authentication header includes the extended 64-bit addresses of the two ends) so dynamic local addresses assignment as proposed should not be problematic though address translation/mapping would be.
  • 802.15.4 has many optional features that may not work with bridging. Superframes, TSCH, DSMA are among features that would require further thinking. Focus should be on making basic features work.
  • 16-bit addressing was popular early on but was acknowledged as not unique and most companies have moved on using 64-bit addresses.
  • A device may move between subLANs. BARC would need to re-assign its address to a new address. Registration and deregistration for the type of information that is to be bridged could be needed. BARC has two systems: peer-to-peer and registrar. The registrar system could manage moving addresses. BARC is being specified in P802.1CQ draft 0.7 that is not yet in WG ballot so such specifics can be addressed.
  • The background for deprecating the mapping of an EUI-48 to an EUI-64, as indicated on slide 7, was discussed.

Disposition: Call to Action per slide 11 to potentially feed back into the development of P802.1CQ.

4. Next meeting. The 802.1 chair led discussion:

  • Suggestions made to meet at the Mar 2022 and May 2022 sessions and in Feb 2022 in the context of 802.15 WNG.
  • SCs or interest groups in 802.15 and perhaps 802.11 could help understand what needs to be done in 802.1. Prioritizing the topics presented as part of agenda item 3.1 could help determine a way forward. As an example, 802.1 and 802.11 had joint meetings leading to 802.11ak.
  • Request made about what 802.1 considers to be the advantages of bridging vs. routing. At a high-level, bridging offers reasonably reliable multicast and ‘who’ addresses (as opposed to ‘where’ addresses). The 2016 contribution referenced in the presentation made as part of agenda item 3.2 explored bridging because the routing overhead was too large given the small packets.
  • Suggestion made to meet several times during the Mar 2022 plenary session to avoid delaying further discussion to May 2022. Such scheduling could be discussed in the Feb 2022 meeting.
  • Observation made that further use cases exist beyond that of bridging 64-bit MAC addresses between 802.15.4 networks (as presented as part of agenda item 3.2) exist. These use cases include interfacing 802.15.4 with the internet, Wi-Fi or other non-802.15.4 networks. Such use cases could be added to the list of topics to prioritize before projects are proposed.

Disposition: Agreed (informally, none dissenting) for 802.1 and 802.15 to meet jointly in:

  • Feb 2022. Tentative agenda items could include a short presentation from an 802.1 participant per the disposition of agenda item 3.1, discussion to prioritize identified topics.
  • Mar 2022, during the 802 plenary session.

Dates and times to be communicated post-meeting once determined by 802.1 and 802.15 leadership.

5. Any other Business. No other business was discussed in this meeting.
