                Network Device YANG Organizational Model
                 draft-rtgyangdt-rtgwg-device-model-00

Abstract

   This document presents an approach for organizing YANG models in a
   comprehensive structure that defines how individual models may be
   composed to configure and operate network infrastructure and
   services.  The structure is itself represented as a YANG model rooted
   at a device, with all of the related component models logically
   organized in a way that is operationally intuitive. 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.

Internet-Draft     Network Device YANG Organizational Model    July 2015

1.  Introduction

   "Operational Structure and Organization of YANG Models" [OC-STRUCT],
   highlights the value of organizing individual, self-standing YANG
   [RFC6020] models into a more comprehensive device-level model.  This
   document builds on that work and presents a derivative structure for
   use in representing the networking infrastructure aspects of physical
   and virtual devices.

   This document aims to provide an extensible structure that can be
   used to tie together other models. It allows for existing, emerging,
   and future models. The overall structure can be constructed using
   YANG augmentation and imports.

   Additional motivation for this work can be found in [OC-STRUCT].

   The approach taken in this (and the original) document is to organize
   the models describing various aspects of network infrastructure,
   focusing on devices, their subsystems, and relevant protocols
   operating at the link and network layers.  The proposal does not
   consider a common model for higher level network services, nor does
   it specify details of how hardware-related data should be organized.
