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 also
   in some existing network scenarios, some customers may require
   network connectivity services with advanced features comparing to
   conventional VPN services.  Such kind of network service is called
   enhanced VPNs (VPN+).  VPN+ can be used, for example, to deliver IETF
   network slice services.

   A VTN is a virtual underlay network that is associated with a network
   topology, and is allocated with a set of dedicated or shared
   resources from the underlay physical network.  VPN+ services can be
   delivered by mapping one or a group of overlay VPNs to the
   appropriate VTNs as the virtual underlay.  For packet forwarding in a
   specific VTN, some fields in the data packet are used to identify the
   VTN the packet belongs to, so that VTN-specific processing can be
   performed on each node along a VTN-specific path.

   This document specifies a new IPv6 Hop-by-Hop option to carry the VTN
   related information in data packets, which could be used to identify
   the VTN-specific processing to be performed on the packets by each
   network node along a VTN-specific path.
