Re: [TICTOC] New Version Notification for draft-jiang-tictoc-syncphy-yang-00.txt

[Lvjingfei <[e-mail]>]

Dear Tal,

I’m attending Q13 (ITU-T Study Group 15 Question 13) meeting, until now, there is no documents about Sync YANG model (including physical layer sync and PTP sync).

As you know, Yuanlong and others finished PTP yang model (RFC 8575) at the past years. This reminded me whether IETF can have a document to define physical layer sync YANG model. Then Yuanlong helped to prepare this original document.

I think if TicToc group thinks this is an useful topic, and some liaisons between TicToc and Q13 may be helpful. Then, some Q13 experts can involve in this work if they’re interested.

Thanks,

Best regards,

Jingfei

Dear Tal,



In general, Q14 in ITU-T SG15 is responsible for developing the standards on transport equipment specific management requirements and information model, and then mapping the UML model into YANG using some tools.

There are some work items projected on data models for Ethernet transport network element, MPLS-TP, and even a work item on synchronization management data model based on G.7721.

But the models in ITU-T are top-down, and usually are based on the ONF core model. G.7721 is targeted at telecom equipment with full-fledged synchronization capability.

As shown in the following figure for G.7721:

While the data models developed in the IETF are bottom-up, and are not dependent on the ONF core model. Just as the model in this Sync-PHY shows, it is simple, independent, and decoupled from other models such as PTP models.

Thus it is more convenient to be integrated and implemented by smaller devices such as those in the industrial internet.



One of our coauthors, Jingfei, is also a regular attendee for Q13/SG15, maybe he has more to say on this topic.



Thanks,

Yuanlong

Hi Yuanglong,



Thanks for putting this draft together.

In general, does the ITU-T publish YANG models?

Anyway, it would be interesting to hear the feedback of the people at

Q13 in the ITU-T.



Cheers,

Tal.
