                   A YANG Module for uCPE management.
                      draft-shytyi-opsawg-vysm-08

Abstract

   This document provides a YANG data model for uCPE management (VYSM)
   and definition of the uCPE equipment.  The YANG Model serves as a
   base framework for managing an universal Customer-Premises Equipment
   (uCPE) subsystem.  The model can be used by a Network Orchestrator.

1.  Introduction

   Network Function Virtualization is a technology that allows to
   virtualize the network services running on dedicaded hardware.  This
   technology became a base for universal Customer-Premises Equipment
   (uCPE).  This document defines the uCPE as harware with x86
   capabilities that has a hypervisor.  In other words, uCPE is a host
   that may run multiple Virtual Machines with guest OSs, where each
   Guest OS may represent a Physical Network Function.  This document
   presents the YANG Model (VYSM) to manage from an Orchestrator the
   infrastructure inside the uCPE.

2.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

   Link - is an entity that enables link layer communication of nodes.

   Port - node connector to the link.

   NE - Network Element.
