This document defines two YANG 1.1 modules to support the configuration of UDP clients and UDP servers.¶
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.¶
This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.¶
Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet-Drafts is at https://datatracker.ietf.org/drafts/current/.¶
Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."¶
This Internet-Draft will expire on 16 August 2024.¶

This documents defines two YANG 1.1 [RFC7950] modules to support the configuration of UDP clients and UDP servers, either as standalone or in conjunction with configuration of other protocol layers.¶
The "ietf-udp-client" YANG module defines the "udp-client-grouping" grouping for configuring UDP clients.¶
The following tree diagram [RFC8340] illustrates the "udp-client-grouping" grouping:¶
module: ietf-udp-client
grouping udp-client-grouping:
+-- remote-address inet:ip-address-no-zone
+-- remote-port inet:port-number
¶
The "ietf-udp-client" YANG module defines the "udp-client-grouping" grouping.¶

<CODE ENDS>¶
Following the guidelines for UDP applications defined in [RFC8085], "applications that need to protect their communications against eavesdropping, tampering, or message forgery SHOULD employ end-to-end security services provided by other IETF protocols". A UDP client and server can use DTLS [RFC9147] [RFC7525] to encrypt the payloads.¶
For configuring a UDP application with DTLS encryption, the groupings "tls-client-grouping" and "tls-server-grouping" defined in "ietf-tls-client" and "ietf-tls-server" modules can be used [I-D.ietf-netconf-tls-client-server].¶
This document describes the URIs from IETF XML Registry and the registration of a two new YANG module names¶
IANA is requested to assign two new URI from the IETF XML Registry [RFC3688]. The following two URIs are suggested:¶
URI: urn:ietf:params:xml:ns:yang:ietf-udp-client Registrant Contact: The IESG. XML: N/A; the requested URI is an XML namespace.¶
URI: urn:ietf:params:xml:ns:yang:ietf-udp-server Registrant Contact: The IESG. XML: N/A; the requested URI is an XML namespace.¶
This document also requests two new YANG module names in the YANG Module Names registry [RFC8342] with the following suggestions:¶
name: ietf-udp-client namespace: urn:ietf:params:xml:ns:yang:ietf-udp-client prefix: udpc reference: RFC-to-be¶
name: ietf-udp-server namespace: urn:ietf:params:xml:ns:yang:ietf-udp-server prefix: udps reference: RFC-to-be¶
The authors would like to thank xxx for their review and valuable comments.¶
