Title : Protocol Independent Use Cases for an Interface to the Routing System

Programmatic interfaces to provide control over individual forwarding
devices in a network promise to reduce operational costs while
improving scaling, control, and visibility into the operation of
large scale networks. To this end, several programmatic interfaces
have been proposed. OpenFlow, for instance, provides a mechanism to
replace the dynamic control plane processes on individual forwarding
devices throughout a network with off box processes that interact
with the forwarding tables on each device. Another example is
NETCONF, which provides a fast and flexible mechanism to interact
with device configuration and policy.
There is, however, no proposal which provides an interface to all
aspects of the routing system as a system. Such a system would not
interact with the forwarding system on individual devices, but rather
with the control plane processes already used to discover the best
path to any given destination through the network, as well as
interact with the routing information base (RIB), which feeds the
forwarding table the information needed to actually switch traffic at
a local level.
This document describes a set of use cases such a system could
fulfill. It is designed to provide underlying support for the
framework, policy, and other drafts describing the Interface to the
Routing System (I2RS).
