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.¶
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.¶
The following terms are defined in [RFC7950] and are not redefined here: client, data model, data tree, feature, extension, module, leaf, leaf-list, and server.¶
This section defines a YANG 1.1 module called "ietf-quic-client".¶
This section presents an overview of of the "ietf-quic-client" module in terms of features and groupings.¶
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 [RFC9645] and [I-D.ietf-netconf-udp-client-server] respectively.¶
The "ietf-quic-client" module defines the following "grouping" statement:¶
This grouping is presented in the following subsection.¶
The following tree diagram [RFC8340] illustrates the "quic-client" grouping:¶
grouping quic-client: +---u tlsc:tls-client-grouping | {tlscmn:tls13 and not tlscmn:tls12}? +---u udpc:udp-client¶
Comments:¶
The "ietf-quic-client" module augments the "/ncs:netconf-client/ncs:initiate" container [I-D.ietf-netconf-netconf-client-server] with the "if-feature" "quic-initiate".¶
This augment enables configuration of QUIC-level parameters for NETCONF client connections.¶
The following tree diagram [RFC8340] illustrates the "quic-client" augmentation of "netconf-client":¶
augment /ncc:netconf-client/ncc:initiate: augment /ncc:netconf-client/ncc:initiate/ncc:netconf-server /ncc:endpoints/ncc:endpoint/ncc:transport: +--:(quic) {quic-initiate}? +--rw quic +---u quicc:quic-client¶

<CODE ENDS>¶
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 [RFC9645] 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.¶
