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
has a network topology and a set of network resources allocated from
the physical underlay 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 have 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 VTNs.

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