Traditionally, routing systems have implemented routing and signaling
(e.g., MPLS) to control traffic forwarding in a network. Route
computation has been controlled by relatively static policies that
define link cost, route cost, or import and export routing policies.
Requirements have emerged to more dynamically manage and program
routing systems due to the advent of highly dynamic data-center
networking, on-demand WAN services, dynamic policy-driven traffic
steering and service chaining, the need for real-time security threat
responsiveness via traffic control, and a paradigm of separating
policy-based decision-making from the router itself. These
requirements should allow controlling routing information and traffic
paths and extracting network topology information, traffic
statistics, and other network analytics from routing systems.
This document proposes meeting this need via an Interface to the
Routing System (I2RS).
This document is a product of the Interface to the Routing System Working Group of the IETF.
