Abstract

   Network abstraction is a technique that can be applied to a network 
   domain to select network resources by policy to obtain a view of 
   potential connectivity
   
   Network slicing is an approach to network operations that builds on 
   the concept of network abstraction to provide programmability, 
   flexibility, and modularity.  It may use techniques such as Software
   Defined Networking (SDN) and Network Function Virtualization (NFV)
   to create multiple logical (virtual) networks, each tailored for a
   set of services that are sharing the same set of requirements, on 
   top of a common network.

   These logical networks are referred to as transport network slices. 
   A transport network slice does not necessarily represent dedicated
   resources in the network, but does constitute a commitment by the 
   network provider to provide a specific level of service.

   The Abstraction and Control of Traffic Engineered Networks (ACTN)
   defines an SDN-based architecture that relies on the concepts of 
   network and service abstraction to detach network and service 
   control from the underlying data plane. 
   
   This document outlines the applicability of ACTN to transport 
   network slicing in an IETF technology network.  It also identifies
   the features of network slicing not currently within the scope of 
   ACTN, and indicates where ACTN might be extended.
