3. IETF New Work summary

  - Applications and Real-Time Area

    o WebRTC Ingest Signaling over HTTPS (WISH)

      This new WG was chartered on 2021-02-05. See
      https://datatracker.ietf.org/wg/wish/about/

  - Security Area

    o DANE AutheNtication for IoT Service Hardening (DANISH)

      This BOF will explore the topic of using DANE and related DNS 
      technologies, in conjunction with certificates and PKIX, in 
      various applications and related protocols. Russ Housley noted 
      that this may be of interest to 802.1X.


4. 802 New Work summary

  - 802.1Qdq Amendment: Shaper Parameter Settings for Bursty Traffic 
    requiring Bounded Latency

    The 802.1Q-2018 standard specifies Bridges that interconnect 
    individual LANs, each supporting the IEEE 802 MAC Service using a 
    different or identical media access control method, to provide 
    Bridged Networks and VLANs. This amendment will add an informative 
    annex that describes recommended shaper parameter settings for 
    bursty traffic requiring bounded latency.

  - 802.1ASdr - Amendment: Inclusive Terminology

    This amendment to 802.1AS-2020 will change the non-inclusive terms, 
    including those identified by IEEE P1588g and IEEE editorial staff, 
    replacing them with suitable and inclusive terminology wherever 
    possible.

  - 802.1DP Standard: Time-Sensitive Networking Profile for Aerospace 
    Onboard Ethernet Communications

    Glenn Parsons reported that this PAR was approved at the November 
    2020 Plenary meeting. This standard will specify profiles of IEEE 
    802.1 Time-Sensitive Networking (TSN) and IEEE 802.1 Security 
    standards for aerospace onboard bridged IEEE 802.3 Ethernet 
    networks. The profiles select features, options, configurations, 
    defaults, protocols, and procedures of bridges, end stations, and 
    Local Area Networks to build deterministic networks for aerospace 
    onboard communications.

  - 802.11bh Amendment: Enhanced service with randomized MAC addresses
  - 802.11bi Amendment: Enhanced service with Data Privacy Protection	

    Dorothy Stanley reported that these PARs were approved at the 
    November 2020 Plenary meeting. The 802.11bh amendment to IEEE 
    Standard 802.11-2016 specifies modifications to the IEEE Std 802.11 
    medium access control (MAC) specifications that preserve the 
    existing IEEE Std 802.11 mechanisms that might otherwise be 
    restricted in environments where STAs in an ESS use randomized or 
    changing MAC addresses, without decreasing user privacy. User 
    privacy concerns include exposure of trackable information to third 
    parties or exposure of an individual's presence or behavior.

    The 802.11bi amendment to IEEE Standard 802.11-2016 specifies 
    modifications to the IEEE Std 802.11 medium access control (MAC) 
    specification to specify new mechanisms that address and improve 
    user privacy.

    Dorothy Stanley noted that the group had previously discussed 
    potential overlap between this work and the IETF MADINAS BOF. Éric 
    Vyncke replied that MADINAS will not officially meet at IETF 110, 
    but there will likely be a side meeting; the plan is to have 
    another BOF at IETF 111 in July if there is enough energy to do the 
    work.

    Alissa Cooper asked whether the 802.11bh and 802.11bi work should 
    be pointed out to the IETF so that people can follow it. Éric Vyncke 
    and Warren Kumari will forward the appropriate links to the INT and 
    OPS Areas, respectively.


5. Review current coordination items

  - Item 5. Enabling use of Local Addresses for virtualization and IoT

    Glenn Parsons reported that they are waiting for the editor of IEEE 
    802.1CQ to update the draft based on comments received; there is not 
    yet anything stable enough to share.

    Pascal Thubert noted that draft-ietf-6lo-ap-nd has been published as 
    RFC 8928 and draft-ietf-dhc-mac-assign has been published as RFC 
    8947.


  - Item 25. Layer 2/Layer 3 Interaction for Time-Sensitive Traffic

    János Farkas provided an update via email on IEEE 802.1 TSN:

    The TSN Task Group (TG) page <https://www.ieee802.org/1/tsn> 
    summarizes TSN standards and ongoing projects, and provides a 
    link to the most recent one-page summary: 
    https://www.ieee802.org/1/files/public/docs2021/admin-tsn-summary-0221-v01.pdf.

    IEEE Std 802.1CMde-2020 TSN for Fronthaul amendment has been 
    published to extend the base standard with enhancements to fronthaul 
    profiles, add support for a new fronthaul interface, and new 
    synchronization, and syntonization standards. 

    The TSN profile projects for industrial automation (IEC/IEEE 60802), 
    automotive (P802.1DG), and service provider (P802.1DF) networks are 
    at TG ballot.

    The new P802.1DP project has been just started to specify TSN 
    profiles for aerospace onboard Ethernet networks. The intent is to 
    develop this standard jointly with SAE Avionics Networks AS-1 A2.

    A major milestone has been achieved by publishing the 2020 revision 
    of the IEEE 802.1AS standard, which includes the generalized 
    Precision Time Protocol (gPTP) profile of the IEEE Std 1588-2019 
    Precision Time Protocol. The new features provided by IEEE Std 
    802.1AS-2020 include: multiple gPTP domains, external port 
    configuration, management support for delay asymmetry measurement, 
    Fine Timing Measurement for IEEE 802.11 transport and more. Two 
    projects amending IEEE Std 802.1AS-2020 are underway.

    The P802.1ASdm project specifies hot standby operations between two 
    gPTP domains in order to improve reliability and availability for 
    time synchronization.

    The P802.1ASdn project specifies a YANG data model for the base 
    standard. Furthermore, a corrigendum is underway to correct minor 
    errors in the base standard.

    In addition, a new project is being started to replace non-inclusive 
    terms with inclusive terminology wherever possible.

  - Item 27. Development of YANG models in the IEEE 802

    The YANG projects for LLDP (P802.1ABcu), FRER (P802.1CBcv), and
    an initial set of TSN features (P802.1Qcw) are at WG ballot.

    The P802f project to specify YANG data model for EtherTypes
    including compact and human-readable names is at TG ballot.

    Rob Wilton reported that the YANGsters group is meeting on a regular 
    basis.

  - Item 33. Capability Discovery

    Alvaro Retana reported via email that draft-ietf-lsvr-l3dl and 
    draft-ietf-lsvr-l3dl-signing are in WG Last Call in the LSVR WG.

    Glenn Parsons reported that that on LLDP, there is new work under 
    ballot to add "Support for Multiframe Protocol Data Units." See 
    https://1.ieee802.org/tsn/802-1abdh/


  - Item 34. Reliable and Available Wireless (RAW)

    Deborah Brungard reported that John Scudder will take over as the 
    responsible AD for RAW at IETF 110. She will make sure that the RAW 
    chairs are added to the coordination email list.

  - Possible New Coordination Items

    Glenn Parsons noted that 802.1 sent a liaison 
    <https://datatracker.ietf.org/liaison/1707/> to the IESG about 
    802.1's intent to withdraw IEEE Std 802.1D-2004. 802.1D is the 
    bridging standard, and it will be rolled into 802.1Q. He said that 
    this does not necessarily need a new coordination item, but he 
    wanted to make sure that everyone is aware.

    Rob Wilton asked if the references to 802.1D will go somewhere else.
    Glenn Parsons replied that they are still working on what the 
    landing page for 802.1D will say.

6. Future meeting plans

  Russ Housley and Dorothy Stanley will send out a Doodle poll to 
  schedule the next coordination call sometime before July 2021.


7. Adjourn
