Abstract

   Abstraction and Control of Traffic Engineering (TE) Networks(ACTN)
   refers to the set of virtual network operations needed to
   orchestrate, control and manage large-scale multi-domain TE
   networks, so as to facilitate network programmability, automation,
   and efficient resource sharing.

   As the ACTN architecture considers abstraction as one of the
   important building blocks, this document describes a few
   alternatives methods of abstraction for both packet and optical
   networks. This is an important consideration since the choice of the
   abstraction method impacts protocol design and the information it
   carries.

1. Introduction

   Abstraction and Control of TE Networks (ACTN) describes a method for
   operating a Traffic Engineered (TE) network (such as an MPLS-TE
   network or a layer 1 transport network) to provide connectivity and
   virtual network services for customers of the TE network. The
   services provided can be tuned to meet the requirements (such as
