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

   This document describes a suggested use of resource-aware SIDs to
   build SR based VTNs.
