     Applicability of Abstraction and Control of Traffic Engineered
                    Networks (ACTN) to Enhanced VPN

           draft-lee-rtgwg-actn-applicability-enhanced-vpn-03

Abstract

   The Abstraction and Control of Traffic Engineered Networks (ACTN)
   defines an SDN-based architecture that relies on the concepts of
   network and service abstraction to detach network and service
   control from the underlying data plane.

   This document outlines the overview of ACTN capability and the
   applicability of ACTN to Enhanced VPN. In particular, this document
   also discusses how ACTN features can fulfill some of the
   requirements of the enhanced VPN, which is also known as VPN+
   [VPN+].
