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 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. IEEE Std 802.1AX-2020 Link Aggregation has been published: IEEE Std 802.1Qcr-2020 Asynchronous Traffic Shaping (ATS) has been published.

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 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
