  Framework for Abstraction and Control of Traffic Engineered Networks

                   draft-ietf-teas-actn-framework-14

Abstract

   Traffic Engineered networks have a variety of mechanisms to
   facilitate the separation of the data plane and control plane. They
   also have a range of management and provisioning protocols to
   configure and activate network resources. These mechanisms represent
   key technologies for enabling flexible and dynamic networking. The
   term "Traffic Engineered network" refers to a network that uses any
   connection-oriented technology under the control of a distributed or
   centralized control plane to support dynamic provisioning of end-to-
   end connectivity.

   Abstraction of network resources is a technique that can be applied
   to a single network domain or across multiple domains to create a
   single virtualized network that is under the control of a network
   operator or the customer of the operator that actually owns
   the network resources.

   This document provides a framework for Abstraction and Control of
   Traffic Engineered Networks (ACTN) to support virtual network
   services and connectivity services.
