1. Introduction
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.
2. The "ietf-udp-client" Module
The "ietf-udp-client" YANG module defines the "udp-client-grouping"
grouping for configuring UDP clients.
2.1. The "udp-client-grouping" Grouping
The following tree diagram [RFC8340] illustrates the "udp-client-
grouping" grouping:

4. Security Considerations
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].
5. IANA Considerations
This document describes the URIs from IETF XML Registry and the
registration of a two new YANG module names
5.1. URI
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

5.2. YANG module name
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
