Hi draft-ietf-teas-te-service-mapping-yang authors,

Thanks for updating.

In terms of our requirement discussed in "consideration of 1 VPN to N VNs mapping" thread, as Qin proposed the followings in https://mailarchive.ietf.org/arch/msg/teas/xJx323vJbcqVY7eZKuBOEDswFzk/ ,


>standard profile (such as golden, silver) can not be simply seen as network performance constraint. QoS parameters in custom profile (e.g., latency) should be seen as SLA contract set between customer and operator, which is still a little different from network performance constraints used for path computation.

>target-class-id is used to identify each match flow and have one to one relationship with custom qos profile since class-id is defined under custom case for each class of data flow.

>Secondly, we can map one VPN into one VN with multiple VN members, each VN member describe connective from one site to another destination site and can support different QoS requirement which is similar to using site-network-access to support different QoS requirements.
>Does this satisfy your use case?


How about the following changes in order to map vn-member(VNAP) to a customer profile corresponding to each match flow per site-network-access?

     augment /l3vpn-svc:l3vpn-svc/l3vpn-svc:sites/l3vpn-svc:site
               /l3vpn-svc:site-network-accesses/l3vpn-svc:site-network-access
               /l3vpn-svc:service/l3vpn-svc:qos/l3vpn-svc:qos-profile/l3vpn-svc:classes
               /l3vpn-svc:class:
       +--rw (te)?
          +--:(vn)
             +--rw vn-ap
                     -> /vn:ap/access-point-list/vn-ap/vn-ap-id

Thanks,
Kenichi

Abstract:
   This document provides a YANG data model to map customer service
   models (e.g., the L3VPN Service Model (L3SM)) to Traffic Engineering
   (TE) models (e.g., the TE Tunnel or the Virtual Network (VN) model).
   This model is referred to as TE Service Mapping Model and is
   applicable generically to the operator's need for seamless control
   and management of their VPN services with TE tunnel support.

   The model is principally used to allow monitoring and diagnostics of
   the management systems to show how the service requests are mapped
   onto underlying network resource and TE models.
