Re: [OPSAWG] New Version Notification for draft-dbwb-opsawg-sap-00.txt

Hi, all,

I have read this short draft and it is well written. I support the adoption of it since it provides a good management tool for service attachment management. A few suggestions to this drafts:

1. If the customer want to open a new line, can we add an usage example to show what kind of capability can be exposed from domain controller to the upper layer application?

2. I think we should emphasize L3NM or L2NM used to configure VPN while this model is used for capability exposure.

3. if L3VPN service is allocated to an logical interface, for instance, an ethernet sub-interface, how do we support this interface type? e.g., extend  if:interface-type to support such interface type? or reference IANA Interface Type defined in RFC7224?

It can be used to build a network topology to be consumed by an orchestrator to handle a service request. SAPs can be the PE endpoint facing a CE or a peer PE (for services such as inter-AS VPN).

> Abstract:
>   This document defines a YANG data model for representing an abstract
>   view of the provider network topology containing the points from
>   which its services can be attached (e.g., basic connectivity, VPN,
>   network slices).  The data model augments the 'ietf-network' data
>   model by adding the concept of service attachment points (SAPs).  The
>   service attachment points are the points to which network services
>   (such as L3VPN or L2VPN) can be attached.  The customer endpoint of
>   an attachment circuits are not covered in the SAP network topology.
