                Network Device YANG Logical Organization
                    draft-ietf-rtgwg-device-model-02

Abstract

   This document presents an approach for organizing YANG models in a
   comprehensive logical structure that may be used to configure and
   operate network devices.  The structure is itself represented as an
   example YANG model, with all of the related component models
   logically organized in a way that is operationally intuitive, but
   this model is not expected to be implemented.  The identified
   component modules are expected to be defined and implemented on
   common network devices.

   This document is derived from work submitted to the IETF by members
   of the informal OpenConfig working group of network operators and is
   a product of the Routing Area YANG Architecture design team.

1.  Introduction

   "Operational Structure and Organization of YANG Models"
   [I-D.openconfig-netmod-model-structure], highlights the value of
   organizing individual, self-standing YANG [RFC6020] models into a
   more comprehensive structure.  This document builds on that work and
   presents a derivative logical structure for use in representing the
   networking infrastructure aspects of physical and virtual devices.
   [I-D.openconfig-netmod-model-structure] and earlier versions of this
   document presented a single device-centric model root, this document
