                 Traffic Engineering Common YANG Types
                    draft-ietf-teas-yang-te-types-01

Abstract

   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] and [RFC7950] is a data modeling language used to
   model configuration data, state data, Remote Procedure Calls, and
   notifications for network management protocols such as 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, e.g. in models defined in
   [I-D.ietf-teas-yang-te], [I-D.ietf-teas-yang-te-topo] and
   [I-D.ietf-teas-yang-rsvp]).

1.1.  Terminology

   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
