Abstract:
Enhanced VPN (VPN+) aims to provide enhanced VPN service to support
some application's needs of enhanced isolation and stringent
performance requirements. VPN+ requires integration between the
overlay VPN connectivity and the characteristics provided by the
underlay network. A Virtual Transport Network (VTN) is a virtual
underlay network which consists of a subset of network resources
allocated on network nodes and links in a customized topology of the
physical network. A VTN could be used as the underlay to support one
or a group of VPN+ services.
In some network scenarios, each VTN can be associated with a unique
logical network topology. This document describes a mechanism to
build the SR based VTNs using IS-IS Multi-Topology together with
other well-defined IS-IS extensions.
