Re: [Lime] I-D Action: draft-ietf-lime-yang-oam-model-02.txt

Dear Authors, et. al,

thank you for updating the model and clarifying its applicability. Below are my notes on the new version that we can discuss on the list and/or at the meeting:

*         I think that the list in the description includes technologies, i.e. mpls, that are not connection-oriented:

"this is the base identy of technology types which are TRILL,mpls,vpls etc";

perhaps mpls-tp would be better.

and s/indent/identity/

*         I think that Interval must have been set of values, not int32 without a range. I believe that anything less than 3.3 millisecond would not be supported by any OAM protocol. But 3.3 msec cannot be configured through current definition of the Interval. That can be done if Interval being expressed in microseconds. But we still don't need range, we need set 3.3 msec, 10 msec, 100msec, 1 sec, 10 sec. 1 minute and 10 minutes are questionable. These are intervals from Ethernet OAM. RFC 7419 recommends somewhat different set of intervals for HW-based implementation of BFD - 3.3 msec, 10 msec, 20 msec, 50 msec, 100 msec, and 1 sec.

I've noticed some Nits and nits in the text. The former

Summary: 1 error (**), 0 flaws (~~), 2 warnings (==), 1 comment (--).

you can fix and check with idnits in verbose mode on Community Tools page. I can help with the latter if you kindly can share MS format of the document.

                Regards,

                                Greg

Abstract:

   This document presents a base YANG Data model for connection oriented

   OAM protocols.  It provides a technology-independent abstraction of

   key OAM constructs for connection oriented protocols.  Based model

   presented here can be extended to include technology specific

   details.  This is leading to uniformity between OAM protocols and

   support nested OAM workflows (i.e., performing OAM functions at

   different levels through a unified interface).
