Dear teas drinkers, 

Since ACTN is a key output of the TEAS working group, and because Network Slicing continues to be a subject of interest, we thought we should resume the following I-D:

Applicability of Abstraction and Control of Traffic Engineered Networks (ACTN) to TE Network Slicing
https://datatracker.ietf.org/doc/draft-king-teas-applicability-actn-slicing/

You might remember the main purpose of this document was to show how ACTN is an applicable technology for requesting, provisioning, and managing network slices in TE and transport networks. In particular, it draws on a lot of published RFCs and a number of YANG models that are being worked on (including in TEAS) to show how a management system can be put together using existing building blocks.

Yes! We are aware that there is work going on in the Network Slicing Design Team to refine definitions that apply to network slicing. It is not our intention to subvert that work, and we have kept the number of terms that we have defined to a basic minimum and we scope those definitions to just this document. We also know that the Design Team plans to include some text on the applicability of ACTN, but we feel that that is most likely to be just a few paragraphs in a bigger document. As you can see from this document, we think that the subject requires a few more words. 

What next? Obviously, we believe we have some more work to do on this document. Several areas for discussion present themselves, including:

o to specify the slice-related model applicability, on both CMI and MPI; 
o to have an architectural match between ACTN and TS arch (we notice similar work in the DT draft);
o to evaluate the multi-technology, such as packet-optical and/or PON+OTN as slice delivery;

We would welcome any review or comments.

Dan, John and Haomian.

Abstract:
   Network abstraction is a technique that can be applied to a network
   domain that utilizes a set of policies to select network resources
   and obtain a view of potential connectivity across the network.

   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 or virtual networks, each tailored for a set
   of services share the same set of requirements.

   Abstraction and Control of Traffic Engineered Networks (ACTN) is
   described in RFC 8453.  It defines an SDN-based architecture that
   relies on the concept 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 a Traffic Engineering (TE) network that utilizes IETF
   technology.  It also identifies the features of network slicing not
   currently within the scope of ACTN, and indicates where ACTN might be
   extended.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
