1. Introduction
This documents defines two YANG 1.1 [RFC7950] modules to support the
configuration of QUIC clients and QUIC servers (QUIC is defined in
[RFC9000]), either as standalone or in conjunction with configuration
of other protocol layers.

2. The "ietf-quic-client" Module
This section defines a YANG 1.1 module called "ietf-quic-client".
2.1. Data model overview
This section presents an overview of of the "ietf-quic-client" module
in terms of features and groupings.
2.1.1. Features
The module itself does not define any features. However, in order to
require TLS 1.3 the following "if-feature" is defined "tlscmn:tls13
not tlscmn:tls12". For QUIC TLS requirements see [RFC9001].
For further details about available features see the "ietf-tls-
client" and "ietf-udp-client" modules. defined in
[I-D.ietf-netconf-tls-client-server] and
[I-D.ietf-netconf-udp-client-server] respectively.
2.1.2. Groupings
The "ietf-quic-client" module defines the following "grouping"
statement:
* quic-client-grouping
This grouping is presented in the following subsection.
2.1.2.1. The "quic-client-grouping" Grouping
The following tree diagram [RFC8340] illustrates the "quic-client-
grouping" grouping:
module: ietf-quic-client
grouping quic-client-grouping:
+---u tlsc:tls-client-grouping
| {tlscmn:tls13 and not tlscmn:tls12}?
+---u udpc:udp-client-grouping
Comments:
* This grouping uses the "tls-client-grouping" grouping discussed in
[I-D.ietf-netconf-tls-client-server]. Note that QUIC requires
TLS 1.3 (or later), thus the "if-feature" invariant "tlscmn:tls13
and not tlscmn:tls12" is defined for this grouping.
Andersson Expires 1 January 2025 [Page 3]
Internet-Draft Groupings for QUIC clients and servers June 2024
* This grouping uses the "udp-client-grouping" grouping discussed in
[I-D.ietf-netconf-udp-client-server].
2.2. YANG Module
This YANG module has normative references to
[I-D.ietf-netconf-tls-client-server] and
[I-D.ietf-netconf-udp-client-server].

4. Security Considerations
This section follows the template defined in Section 3.7.1 of
[RFC8407].
The YANG modules specified in this document defines a schema for data
that is designed to be accessed via network management protocols such
as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer
is the secure transport layer, and the mandatory-to-implement secure
transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer
is HTTPS, and the mandatory-to-implement secure transport is TLS
[RFC8446].
The Network Configuration Access Control Model (NACM) [RFC8341]
provides the means to restrict access for particular NETCONF or
RESTCONF users to a preconfigured subset of all available NETCONF or
RESTCONF protocol operations and content.
The modules presented in this draft does not contain any protocol
accessible nodes, and thus the security considerations for such are
not provided here.
Furthermore, the modules defines groupings, these considerations are
primarily for the designers of other modules that use these
groupings.
Security considerations for the groupings used in the modules are
discussed in [I-D.ietf-netconf-tls-client-server] and
[I-D.ietf-netconf-udp-client-server], refer to these documents for
further details.
Since the modules does not define any RPCs or actions or
notifications, and thus the security considerations for such are not
provided here.
5. IANA Considerations
5.1. The "IETF XML" Registry
This document registers two URIs in the "ns" subregistry of the IETF
XML Registry [RFC3688] maintained at
https://www.iana.org/assignments/xml-registry/xml-registry.xhtml#ns.
Following the format in [RFC3688], the following registration is
requested:
