Hi Gyan, Thanks for your comments. Yes this document extends the single domain VTN mechanisms to multi-domain network scenarios, which could be used for the end-to-end IETF network slicing and further for 5G end-to-end network slicing.
This document proposes several optional types of VTN Binding SIDs (functions), each may be applicable in a particular case. Feedbacks on these BSID types are appreciated.

This draft will be very useful for 5G E2E multi domain network slicing VTN provisioning and E2E concatenation of SR-TE BSID per domain hop BSID list E2E path instantiation.

The term “IETF network slice” was chosen by the network slicing design team in TEAS WG, after many discussion in both the design team and the WG. This document tries to align with the terminology there. I also agree that the terms in different SDOs needs to be aligned, or the relationship and mapping between different terms could be defined.

However, I have some concerns about the term of "IETF slicing”, from the perspective of operator, the terms of “IETF slicing” and “3GPP slicing” may be confusing, there should be a universal set of terms of slicing across different SDOs, even they may cover different sections or layers of the network system. What’s your opinion? Best regards Chongfeng 2021年5月14日 下午4:10，Dongjie (Jimmy) <[email protected]<mailto:[email protected]>> 写道： Hi WG, Recently we published a new draft on Segment Routing for End-to-End IETF Network Slicing: https://datatracker.ietf.org/doc/html/draft-li-spring-sr-e2e-ietf-network-slicing It introduces the new SRv6 behaviors and SR-MPLS BSIDs to enable the mapping and concatenation of multi-domain IETF network slices. This document is aligned with the framework for end-to-end IETF network slicing as described in draft-li-teas-e2e-ietf-network-slicing. Your review and comments are welcome.
