Re: [spring] WG Adoption Call for draft-dong-spring-sr-for-enhanced-vpn

"Thus, from a purely technical point of view, I see no reason for this document to be adopted.”

Could you please explain the technical point why this document can’t be adopted?

IMO, all your statements just show support and consensus on the technology.

Hi WG/authors,

I have to point out that the VTN-ID in draft-dong-spring-sr-for-enhanced-vpn is actually the AII in draft-peng-teas-network-slicing, just a new name. That can be seen from the evolution of the historical versions of the these two drafts.

I draw your attention to draft draft-peng-teas-network-slicing which analyzes in detail the reasons for the introduction of slice identifier (AII) in the network, and maintains the resource partition of each slice and the allocation of SID per AII in the network. All this happened before draft-dong-spring-sr-for-enhanced-vpn.

In addition, the idea that multiple slices share the same virtual topology (such as flex-algo) is also copied from draft-bestbar-teas-ns-packet, which can significantly reduce the state in the network, especially without maintaining SPT per slice, which means that multiple SIDs per slice can share the forwarding action of SPT per VN and at the same time can do resource guarantee by SID per slice (or slice-id in packet).

Thus, from a purely technical point of view, I see no reason for this document to be adopted.

Regards,

PSF

Dear WG:

This message starts a 2 week WG adoption call for https://datatracker.ietf.org/doc/draft-dong-spring-sr-for-enhanced-vpn/ ending February 10th 2021.

After review of the document please indicate support (or not) for WG adoption to the mailing list and if you are willing to work on the document, please state this explicitly. This gives the chairs an indication of the energy level of people in the working group willing to work on this document.
