                    draft-ietf-ccamp-layer0-types-03

Abstract

   This document defines a collection of common data types and groupings
   in the YANG data modeling language.  These derived common types and
   groupings are intended to be imported by modules that model Layer 0
   optical Traffic Engineering (TE) configuration and state capabilities
   such as Wavelength Switched Optical Networks (WSONs) and Flexi-grid
   Dense Wavelength Division Multiplexing (DWDM) Networks.

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 as well as non-TE features (e.g., physical
   network configuration aspect) for Layer 0 optical networks in
   model(s) defined outside of this document.  The applicability of
   Layer 0 types specified in this document include Wavelength Switched
   Optical Networks (WSONs) [RFC6163] and [ITU-Tg6982], and Flexi-grid
   Dense Wavelength Division Multiplexing (DWDM) Networks [RFC7698] and
