             Common YANG Data Types for Traffic Engineering


   This document defines a collection of common data types and groupings
   in YANG data modeling language.  These derived common types and
   groupings are intended to be imported by modules that model Traffic
   Engineering (TE) configuration and state capabilities.

1.  Introduction

   YANG [RFC6020] [RFC7950] is a data modeling language used to model
   configuration data, state data, Remote Procedure Calls, and
   notifications for network management protocols such as the Network
   Configuration Protocol (NETCONF) [RFC6241].  The YANG language
   supports a small set of built-in data types and provides mechanisms
   to derive other types from the built-in types.

   This document introduces a collection of common data types derived
   from the built-in YANG data types.  The derived types and groupings
   are designed to be the common types applicable for modeling Traffic
   Engineering (TE) features in model(s) defined outside of this

1.1.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "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 terminology for describing YANG data models is found in

1.2.  Prefixes in Data Node Names

   In this document, names of data nodes and other data model objects
   are prefixed using the standard prefix associated with the
   corresponding YANG imported modules, as shown in Table 1.
