Abstract:
   Virtual Private Networks (VPNs) provide different customers with
   logically separated connectivity over a common network
   infrastructure.  With the introduction and evolvement of 5G and other
   network scenarios, some existing or new customers may require
   connectivity services with advanced characteristics comparing to
   traditional VPNs.  Such kind of network service is called enhanced
   VPNs (VPN+).  VPN+ can be used to deliver IETF network slices, and
   could also be used for other application scenarios.

   A Virtual Transport Network (VTN) is a virtual underlay network which
   consists of a set of dedicated or shared network resources allocated
   from the physical underlay network, and is associated with a
   customized logical network topology.  VPN+ services can be delivered
   by mapping one or a group of overlay VPNs to the appropriate VTNs as
   the virtual underlay.  In packet forwarding, some fields in the data
   packet needs to be used to identify the VTN the packet belongs to, so
   that the VTN-specific processing can be performed on each node the
   packet traverses.

   This document proposes a new Hop-by-Hop option of IPv6 extension
   header to carry the VTN related information, which could used to
   identify the set of network resources allocated to a VTN and the
   rules for packet processing.  The procedure of processing the VTN
   option is also specified.
