Abstract 

   This document describes the framework for Enhanced Virtual Private 
   Network (VPN+) service.  The purpose is to support the needs of new 
   applications, particularly applications that are associated with 5G 
   services, by utilizing an approach that is based on existing VPN and 
   TE technologies and adds features that specific services require 
   over and above traditional VPNs. 

   Typically, VPN+ will be used to form the underpinning of network 
   slicing, but could also be of use in its own right providing 
   enhanced connectivity services between customer sites. 

   It is envisaged that enhanced VPNs will be delivered using a 
   combination of existing, modified, and new networking technologies. 
   This document provides an overview of relevant technologies and 
   identifies some areas for potential new work. 

   It is not envisaged that quite large numbers of VPN+ services will be 
   deployed in a network and, in particular, it is not intended that 
   all VPNs supported by a network will use VPN+ related techniques.
