  Framework for Abstraction and Control of Traffic Engineered Networks

                   draft-ietf-teas-actn-framework-05

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.

   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).

Status of this Memo

   This Internet-Draft is submitted to IETF in full conformance with
