         YANG Data Model for SD-WAN VPN service model delivery
                draft-sun-opsawg-sdwan-service-model-00

Abstract

   This document defines a YANG data model that can be used for
   communication between customers and network operators to deliver
   agile, assured IP connectivity, overlay VPN service, which is also
   referred to as SD-WAN VPN Service.  This model provides an abstracted
   view of the SD-WAN service configuration components.  It will be up
   to the management system to take this model as input and use specific
   configuration models to configure the different network elements to
   deliver the service.  How the configuration of network elements is
   done is out of scope for this document.

1.  Introduction

   BGP/MPLS IP VPNs [RFC4364] as widely deployed technology can provide
   IP network connectivity over the backbone between IP VPN sites.
   Though having some similarity with the connectivity services offered
   by BGP/MPLS IP VPNs, SD-WAN(software-defined wide-area network)
   utilizes overlay networking technology and enable application driven
   networking to deliver agile, assured IP connectivity services for
   enterprise customer.

   SD-WAN can be built on top of various underlay networks and allow
   multiple parallel paths between two or more sites . More
   specifically, two sites can be interconnected by a traditional MPLS
   VPN ([RFC4364] or [RFC4664]),or by public Internet using fiber,
