Abstract:

   Virtual Private Networks (VPNs) provide different customers with
   logically separated connectivity over a common network
   infrastructure.  With the introduction 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.  Enhanced VPNs can be used, for example, to deliver
   network slice services.

   A Network Resource Partition (NRP) is a subset of the network
   resources and associated policies on each of a connected set of links
   in the underlay network.  An NRP may be used as the underlay to
   support one or a group of enhanced VPN services.  For packet
   forwarding within a specific NRP, some fields in the data packet
   (which is called NRP Selector) need to be used to identify the NRP to
   which the packet belongs.  In doing so, NRP-specific processing can
   be performed on each node along the forwarding path in the NRP.

   This document specifies a new IPv6 Hop-by-Hop option to carry Network
   Resource related information (e.g., identifier) in data packets.  The
   NR Option can be used to carry NRP Selector ID and related
   information, while it is designed to make the NR option generalized
   for other network resource semantics and functions.
