Just my two cents. All the text you quoted says is, “You can use ACTN to achieve network slicing in networks that support ACTN.” Cheers, Adrian From: Teas <teas-bounces@ietf.org> On Behalf Of Daniele Ceccarelli Sent: 30 August 2021 09:59 To: Vishnu Pavan Beeram <vishnupavan@gmail.com>; TEAS WG <teas@ietf.org> Cc: TEAS WG Chairs <teas-chairs@ietf.org> Subject: Re: [Teas] WG Adoption Poll - draft-king-teas-applicability-actn-slicing-10 Hi WG, while reviewing this draft and the network slice NBI YANG I find a major discrepancy between them. While draft-king-teas-applicability-actn-slicing-10 draft-wd-teas-ietf-network-slice-nbi-yang-04 says that: “ACTN is a toolset capable of delivering network slice functionality. This document outlines the application of ACTN and associated enabling technologies to provide network slicing in a network that utilizes IETF technologies such as IP, MPLS, or GMPLS. It describes how the ACTN functional components can be used to support model-driven partitioning of resources into variable-sized bandwidth units to facilitate network sharing and virtualization.” On the other side we have a network slicing NBI model completely detached from ACTN that says: “The difference between the ACTN VN model and the IETF Network Slice NBI requirements is that the IETF Network Slice NBI is a technology- agnostic interface, whereas the VN model is bound to the IETF TE Topologies. The realization of the IETF Network Slice does not necessarily require the slice network to support the TE technology.” And “However, the Network Slice SLO and Network Slice Endpoint are not clearly defined and there's no direct equivalent.” So is ACTN applicable to network slicing or not? And if yes how? I was expecting to see the NBI model based on the ACTN models with some augmentation to cover the e.g. the non TE parts, the LSO and the endpoints…but we have two completely disjoint modules. I would say that the two drafts are saying exactly the opposite thing, am I missing something?

Please send email to the list indicating "yes/support" or "no/do not support". If indicating no, please state your reservations with the document. If yes, please also feel free to provide comments you'd like to see addressed once the document is a WG document. The poll ends September 10th. Thank you, Pavan and Lou
