                YANG Model for Logical Network Elements
                     draft-ietf-rtgwg-lne-model-10

Abstract

   This document defines a logical network element YANG module.  This
   module can be used to manage the logical resource partitioning that
   may be present on a network device.  Examples of common industry
   terms for logical resource partitioning are Logical Systems or
   Logical Routers.  The YANG model in this document conforms to the
   Network Management Datastore Architecture as defined in RFCXXXX.

1.  Introduction

   This document defines a YANG [RFC6020] module to support the creation
   of logical network elements on a network device.  A logical network
   element (LNE) is an independently managed virtual device made up of
   resources allocated to it from the host or parent network device.  An
   LNE running on a host network device conceptually parallels a virtual
   machine running on a host system.  Using host-virtualization
   terminology one could refer to an LNE as a "Guest", and the
   containing network-device as the "Host".  While LNEs may be
