Meeting Minutes

# IETF 110 - DNSSD + Homenet

12:00-14:00 UTC Friday session I (March 12, 2021)

## 12:00-12:45 DNSSD

Ted Lemon presented summary of current work in DNS-SD

* Service Registration protocol:
* Advertising Proxy:
* SRP Replication: draft TBD * mDNS discovery of DNS-SD browsing zones: draft

Slides: [Combined

Used slides 8-12 for discussion of DNSSD WG items.

Éric Vyncke asked about how SRP Replication will work.
Ted explained why he decided not to use the normal DNS zone transfer mechanism
The normal DNS zone transfer mechanism assumes a distinction between primary
and secondary. SRP Replication is more peer-to-peer. The focus will not be a
complete 100% robust replication protocol with transactions, rather something
that is easy/compact to implement in home devices.

Ted will update
one more time and then we can start Working Group Last Call.

We need more discussion of
on the list, and then we can ask about Working Group adoption.

The SRP Replication draft awaits submission.

## 12:45-14:00 Homenet

### Administrivia and Status (Chairs)

  * [Chair

Agenda bashing took place, and it was agreed to start with the naming
architecture and delegation drafts.

The Homenet Babel profile is still not published because it is waiting on the
BAbel Source Specific draft. That is likely to be rewritten and go back through
WGLC and IETF LC. This will take some time.

### Daniel Migault / Michael Richardson (30 minutes)
* Simple Provisioning of Public Names for Residential Networks
* DHCPv6 Options for Home Network Naming Authority

Slides: [doi and associated dhcp

There was no technical discussion of these drafts and administrative discussion
(how to proceed with them) was deferred to end of session.

### Ted Lemon (15 minutes)

Stuart Cheshire thanked Ted Lemon for his work over the last two years, not
only designing solutions (SRP and Self-configuring Stub Networks) and authoring
drafts, but also writing the code to implement those solutions. This work lead
to Apple shipping the HomePod mini with Thread Border Router functionality in
November 2020, as well as a variety of third-party vendors shipping compatible
HomeKit accessories that run over Thread using Ted’s SRP and Stub Network

* [Self-configuring Stub Networks: Problem
Statement](https://datatracker.ietf.org/doc/draft-lemon-stub-networks-ps/) *
[Connecting Stub Networks to Existing

Ole Trøan asked: Is “full mesh routing” just “routing”?
Ted uses the term “full mesh routing” to mean multiple hops in the home across
an arbitrary topology. The “stub network routing” proposal is an intentional
simplification, where there is a single “backbone” home network with one or
more self-configuring (permissionless) stub networks hanging off that backbone.
That simplification is what makes it possible to add a new self-configuring
stub network to an existing home network without requiring that other devices
on the existing home network (including the home gateway and Wi-Fi access
point) already know about stub networks.

### Administrative Discussion -- How and Where to Proceed

There was discussion of finding the right home in the IETF to progress the stub
network work.

Barbara Stark did a poll asking “Are you interested in working on stub
networks?” Out of 35 people in the meeting, 12 responded “yes” and 1 responded

Barbara Stark did a poll asking “Are you willing to review
draft-ietf-homenet-front-end-naming-delegation for Working Group Last Call?”
Out of 35 people in the meeting, 9 responded “yes” and 1 responded “no”.

Daniel Migault will update the draft one more time and then we will begin
Working Group Last Call.

Plan is to schedule a HOMENET interim meeting in about six weeks for discussion
of stub networks and naming delegation. There will be a Doodle poll to select a
