    A Framework for Enhanced Virtual Private Networks (VPN+) Service
                    draft-dong-teas-enhanced-vpn-03

Abstract

   This document specifies a framework for using existing, modified and
   potential new networking technologies as components to provide an
   Enhanced Virtual Private Networks (VPN+) service.  The purpose is to
   enable VPNs to support the needs of new applications, particularly
   applications that are associated with 5G services.  Typically, VPN+
   can be used to form the underpinning of network slicing, but will
   also be of use in its own right.
