Support this adoption.

1)  Does this informational draft aid operation of 5G networks for new applications?
Yes.

2) Should IDR recommend the global VTN-ID?
I don't think the global VTN-ID is needed.

Subject: [Idr] draft-xie-idr-bgpls-sr-vtn-mt-03.txt - Call for WG adoption: 12/18/2021 to 1/7/2022
This begins a WG Adoption call for draft-xie-idr-bgpls-sr-vtn-mt-03.txt from 12/18 2021 to 1/7/2022.  The longer period is due to the Holiday/New Year time period. 
 
The draft can be found at: 
https://datatracker.ietf.org/doc/draft-xie-idr-bgpls-sr-vtn-mt/
 
While reviewing the document consider the following questions: 
 
1)  Does this informational draft aid operation of 5G networks for new applications? 
 
New 5G services require stringent  performance requirements for applications.  This information draft describes how to use existing segment routing (SR) 
mechanisms to allow a centralized control to allocate a set of  virtual transport networks (VTNs) which are resource aware.  Isolation between resources for multi-AS transport may be necessary to protect the application. 
 
Intra-domain:  
a) Uses MT-ID which identifies 1 or more ISIS/OSPF topologies.
[drafts referenced:  draft-ietf-idr-rfc7752bis, draft-ietf-idr-bgp-ls-segment-routing-ext,  draft-ietf-idr-bgpls-srv6-ext] 
b) New VTN-ID which specifies resources associated with each VTN
[draft referenced: draft-ietf-lsr-isis-sr-vtn-mt] 
 
Inter-Domain mechanisms used include: 
a) Isolation of certain VTNs to specific inter-domain links or BGP peers,  
b) consistent use of MT-ID across multiple domains or use of VTN-ID TLV 
 
VTN-ID TLV is a bgp-ls TLV that specifies unique set of resources per VTN.  
 
[existing WG drafts referenced: draft-ietf-idr-bgpls-segment-routing-epe, draft-ietf-idr-bgpls-srv6-ext, draft-ietf-idr-rfc7752bis] 
New drafts referenced: draft-dong-idr-bgpls-sr-enhanced-vpn-03.txt] 
 
2) Should IDR recommend the global VTN-ID? 
 
The MT-ID is not an IANA registered named space.  VTN-ID is proposed as a global name space, but does not have any proposed IANA registry text.  Should VTN-ID become a register global name space that identifies a set of MT-IDs and other resources?  
 
Cheers, Sue
