I agree with Jeff, or even better, since there is a draft on the applicability of ACTN to network slicing, this one could be used to describe the applicability of VPN+/Enhanced VPN to Network slicing.

Don’t forget about the pending discussion on the relationship between ACTN VN and VTN, I still believe this duality can be easily resolved with an augmentation and have a single solution for network slicing instead of many.

Jie,

I think, it would have been more appropriate to have “vtn/vtn-id” in the draft name, rather than "e2e-ietf-network-slicing"

Cheers,
Jeff

Hi WG,

Recently we published a draft on the framework for end-to-end IETF network slicing: https://datatracker.ietf.org/doc/html/draft-li-teas-e2e-ietf-network-slicing

This document describes the scenarios of end-to-end network slicing, and the framework of network slice mapping between different network segments and network domains. Multiple network slice related identifiers are defined to covers different network scopes.

The network slice related identifiers of different network scopes can be instantiated with MPLS or IPv6 data plane, which are further described in the following drafts:

https://datatracker.ietf.org/doc/draft-li-mpls-e2e-ietf-network-slicing/

https://datatracker.ietf.org/doc/html/draft-li-6man-e2e-ietf-network-slicing

https://datatracker.ietf.org/doc/html/draft-li-spring-sr-e2e-ietf-network-slicing

Your review and comments are welcome. (Comments on the specific data plane draft can go to the corresponding WG mail list).

Best regards,
Jie
