3. IETF New Work Summary

BPF/eBPF (BPF) - Internet Area

Russ Housley noted that the BPF BOF is probably the BOF of most interest
to 802. eBPF is a technology with origins in the Linux kernel that can
run sandboxed programs in a privileged context such as the operating
system kernel. If chartered, the BPF working group will be tasked with
documenting the existing state of the eBPF ecosystem, and a clear
process for extensions, including initial extension that are widely
useful and showcase the process.

Computing-Aware Networking (CAN) - Routing Area

This is a placeholder BOF for a Working Group that is likely to be
chartered before IETF 116. John Scudder said that he does not think it
is relevant to 802.

Domain Boundaries (DBOUND2) - Applications and Real-Time Area

This BOF will discuss whether to re-open the DBOUND Working Group to
work on a problem statement for DNS administrative boundaries.

Key Transparency (KEYTRANS) - Security Area

This BOF will discuss ways to standardize a safe, publicly-auditable way
to distribute cryptographically-sensitive data like public keys.

Structured Email (SML) - Applications and Real-Time Area

The goal of structured email is to replace or extend text-based email
messages with message parts that describe content in a machine-readable
way.

vCon (VCON) - Applications and Real-Time Area

The VCON BOF will discuss chartering a working group will define a
standard container for conversation data and specify mechanisms to
ensure the integrity and privacy of the data in the container.

4. 802 New Work Summary

802.1CS-2020/Cor 1- Link-local Registration Protocol - Corrigendum 1 Corrections to Management Modules and Protocol Encoding, PAR modification

This is a modification to an existing PAR to correct errors in the YANG
module, SNMP MIB and TLV encoding.

802.1ASdm - Amendment: Hot Standby and Clock Drift Error Reduction, PAR modification and CSD

This amendment specifies protocols, procedures, and managed objects for
hot standby without use of the Best Master Clock Algorithm (BMCA), for
time-aware systems, including:

• A function that transforms the synchronized times of two generalized
  Precision Time Protocol (gPTP) domains into one synchronized time
  for use by applications;
• A function that directs the synchronized time of one gPTP domain
  into a different gPTP domain; and- Mechanisms that determine whether
  a gPTP domain has sufficient quality to be used for hot standby.

This amendment specifies a Type-Length-Value (TLV) that allows more
accurate neighbor rate ratio calculation and more accurate tracking of
clock frequency drift. This amendment also addresses errors and
omissions in the description of existing

802.1Qdt - Amendment: Priority-based Flow Control Enhancements, PAR modification and CSD

This amendment specifies procedures and managed objects for automated
Priority-based Flow Control (PFC) headroom calculation and Media Access
Control Security
(MACsec) protection of PFC frames, using point-to-point roundtrip
measurement and enhancements to the Data Center Bridging Capability
Exchange protocol (DCBX).
This amendment places emphasis on the requirements for low latency and
lossless transmission in large-scale and geographically dispersed data
centers.This amendment also addresses errors of the existing IEEE Std
802.1Q functionality.

802.1Qdx - Amendment: YANG Data Models for the Credit-Based Shaper, PAR and CSD

This amendment specifies a Unified Modeling Language (UML)-based
information model and YANG data models that allow configuration and
status reporting for bridges and end
stations (as specified by this standard) with the capabilities currently
specified for the credit-based shaper algorithm (8.6.8.2) of this
standard for the per-traffic class queues. It further defines the
relationship between the information and data model and models for the
other management capabilities specified in this standard.

802.1DU - Standard: Cut-Through Forwarding Bridges and Bridged Networks, PAR and CSD

This standard specifies Cut-Through Forwarding (CTF) bridges based on
the IEEE 802.1Q bridge architecture, including protocols, procedures,
and managed objects. CTF bridges interconnect individual local area
networks (LANs) using different or identical media access control (MAC)
methods with and without support for CTF. This standard also details the
usage of CTF bridges.

5. Review current coordination items

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

Donald Eastlake reported that draft-ietf-intarea-rfc7042bis was adopted
by the INTAREA WG in September 2022 and has since been updated to WG
version -01. The change from -00 to -01 was to include more detail on
internal IETF procedure before applying to the IEEE Registration
Authority for an Ethertype.

Paul Congdon reported that IEEE 802.1 anticipates sending a liaison to
the IETF reviewing the rfc7042bis-01 draft.

Roger Marks reported that IEEE 802.1CQ was sent to the INTAREA WG in a
liaison statement (https://datatracker.ietf.org/liaison/1794/) in
September 2022.

Russ Housley said that at the next coordination meeting, the group
should decide whether this coordination item needs to be kept open for
7042bis, or if it can be closed.

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

János Farkas reported that draft-ietf-detnet-scaling-requirements was
adopted in December 2022. The DETNET WG is planning a virtual interim
meeting on 2023-03-07.

The TSN Task Group is wrapping up work on a couple of documents. IEEE
802.1qcz is finishing ballot comment resolution, and IEEE 802.1qcw will
start recirculation ballot shortly.

Item 27. Development of YANG models in the IEEE 802

Cindy Morgan will check with Rob Wilton about sending a liaison back
from the NETCONF WG to 802.1 on security coordination for
draft-ietf-netconf-keystore.

Item 33. Capability Discovery

Alvaro Retana reported that the L3DL work had been on hold in the LSVR
WG until group could finish other work. He expects to see a recharter of
the LSVR WG to include the L3DL work sometime after IETF 116.

Item 34. Reliable and Available Wireless (RAW)

The group discussed whether this item should be closed due to lack of
energy, but agreed to keep it open because the RAW archictecture draft
is still a hot topic; reviewers for this document are still needed.

Dorothy Stanley proposed scheduling a tutorial on RAW for 802.11 during
their July plenary meeting. Dorothy Stanley and János Farkas will follow
up with Pascal Thubert about a possible tutorial.

Item 35. MAC Address Device Identification for Network and Application Services (MADINAS)

Éric Vyncke reported that the MADINAS WG has been fairly quiet, but this
item should remain open to coordinate MADINAS with P802.1, P802.11bh,
and P802.11bi.

Future meeting plans

Russ Housley said that there do not appear to be any hot topics
requiring a face-to-face meeting at IETF 116. Dorothy Stanley agreed.

Russ Housley said that he does think that trying to schedule a tutorial
on RAW at the 802 meeting in July is a good idea.

Éric Vyncke suggested that it might be helpful to present a brief
introduction on SNAC to 802 in July as well.
