Abstract:

   Enhanced VPNs aim to deliver VPN services with enhanced
   characteristics, such as guaranteed resources, latency, jitter, etc.,
   so as to support customers requirements on connectivity services with
   these enhanced characteristics.  Enhanced VPN requires integration
   between the overlay VPN connectivity and the characteristics provided
   by the underlay network.  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 could be used
   as the underlay to support one or a group of enhanced VPN services.

   Segment Routing (SR) leverages the source routing paradigm.  A node
   steers a packet through an ordered list of instructions, called
   "segments".  A segment can represent topological or service based
   instructions.  A segment can further be associated with a set of
   network resources used for executing the instruction.  Such a segment
   is called resource-aware segment.

   Resource-aware Segment Identifiers (SIDs) may be used to build SR
   paths with a set of reserved network resources.  In addition, a group
   of resource-aware SIDs may be used to build SR based NRPs, which
   provide customized network topology and resource attributes required
   by one or a group of enhanced VPN services.

   This document describes an approach to build SR based NRPs using
   resource-aware SIDs.  The SR based NRP can be used to deliver
   enhanced VPN services in SR networks.
