RE: Re:Adoption Call for <draft-dong-6man-enhanced-vpn-vtn-id>

Hi PSF,

Your comment is about the terminology rather than the technology. Thus I assume you also agree with the HBH based mechanism described in the draft.

The essence of this document is to define a data plane identifier which refers to a subset of network resources allocated on a group of nodes and links. In my understanding the "AII" you mentioned was an identifier in the control plane, which is irrelevant to this draft. 

The term VTN was introduced in draft-ietf-teas-enhanced-vpn (VPN+ framework) for a virtual underlay network, and this document aligns with that terminology. Later the term NRP was introduced in TEAS. The relationship between VTN and NRP will be described in next revision of VPN+ framework, and further discussion could happen in TEAS. If after some discussion it turns out that VTN and NRP are synonymous for TEAS, we are open to align the term in a future version with whatever the TEAS WG prefers.

In summary, IMO we should focus on the technology part here. The coordination on the terminology is needed, while we don't need to worry too much about it. 

Best regards,
Jie
