Abstract:

   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.

   A Virtual Transport Network (VTN) is a virtual underlay network which
   is associated with a network topology, and is allocated with a set of
   dedicated or shared resources from the underlay physical network.

   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 virtual underlay
   networks, which provide customized network topology and resource
   attributes required by one or a group of customers and/or services.
   Such virtual underlay networks are the SR instantiations of VTNs.

   This document describes a suggested approach to build SR based VTNs
   using resource-aware SIDs.  The SR based VTNs can be used to deliver
   RFC XXXX network slices in SR networks.
