Abstract:
Software Defined Networks (SDN) provide a way to virtualize and
abstract the network and present the virtual or abstract resources to
the third-party applications running in software. The application
can utilize a programmable interface to receiving these virtual or
abstract resources in a form that allows monitoring or manipulation
of resources. Various programmatic interfaces have been proposed to
interface directly to the forwarding plane (OpenFlow, ForCES), or do
device configuration (NETCONF). ALTO has proposed a informational
interface to the application. Only the progammatic Interface to the
Routing System (IRS) provides an interface directly to the routing
system to utilize all aspects of the routing system as a system.
The IRS system interacts with the control plane processes to monitor
best paths to any destination and to change the routing information
base (RIB) or MPLS label information Base (LIB) which feeds the
forwarding tables the information needed to actually switch traffic
at a local level.
This document outlines how SDN networks can use the IRS interface to
implement an automated set of network services for Virtual Connection
on Demand (VCoD) and Virtual Network on Demand (VNoD)
