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
   Registrant Contact: The IESG.
   XML: N/A; the requested URI is an XML namespace.

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

   prefix: udps
   reference: RFC-to-be
