Hi Young,

IMO this augmentation has issues:

     augment /nw:networks/nw:network/nw:node/tet:te/tet:tunnel-termination-point:
       +-rw supported-operational-modes*    layer0-types:operational-mode
       +-rw configured-operational-modes?   layer0-types:operational-mode
       +-rw supported-fec-types*            identityref
       +-rw supported-termination-types*    identityref
       +-rw supports-bit-stuffing?          boolean
       +-rw is-tunable?                     boolean
       +-rw max-subcarrier-channel-num?     uint8

supported-operational-modes should be ro

configured-operational-modes should be configured-operational-mode (without "s", singular)

supported-fec-types is normally included in the supported-operational-modes

max-subcarrier-channel-num:  I thought that in case of inverse multiplexing, a termination-point is needed for each (sub-)carrier. There might be carrier-specific
properties that differ from (sub-)carrier to (sub-)carrier. It needs to be clarified also whether the tunnel-termination-point is encompassing all (sub-)carriers that are
forming an inverse multiplexing group.

supports-bit-stuffing: meaning is unclear and the description below doesn't say anything where and how bit-stuffing is applied. This is a property of the
mapping function that maps a client signal into a server layer frame, I suppose.

    leaf supports-bit-stuffing {
       type boolean;
       description
         "Indicates whether bit stuffing is supported by this TTP";


Thanks,
Dieter

Hi,

This revision, we hope, incorporated all comments from Tom and others. The co-authors believe that it is ready for WG LC.

Thanks & best regards,

        Date            : 2018-12-05

Abstract:
   This document provides a YANG data model for the routing and
   wavelength assignment (RWA) TE topology in wavelength switched
   optical networks (WSONs). The YANG data model defined in this
   document conforms to the Network Management Datastore Architecture
   defined in RFC 8342.
