Hi Sergio,

This should be good. We already got the slides from Dieter, and we will add it as an example. Since you are doing this already, can you send me the YANG mapping once you get it done?

Thanks,

- Xufeng

Hi Xufeng, Igor
May be it would be good , based on slides Dieter shown last time, to add a "model mapping" to see real yang entities   involved for TL definition .
We are trying to do this job in Transport Design Team in CCAMP for specific use cases.

What do you think?

Thanks
Sergio

Subject: IETF TE Topology YANG Model Design Meeting Notes - 2017-02-15

Attendees:
Xufeng, Igor, Pavan, Carlo, Sergio, Tarek, Pawel Ka, Dieter

- Continued discussion on multi-layer topologies covering more than 2 layers.
  > Discussed the modeling transformation by using transitional link.
  > A 3-layer hybrid node might be decomposed into 3 logical nodes.
  > Dieter presented the use case of a multi-layer topology with 3 layers.
  > We have confirmed that the existing model can support such a
    modeling transformation.

- Comments from Ievgen seem to be related to TE model (not this
  model). Will respond to the email.

- Draft text
  > Discussed the clarification on customized topology vs. abstract topology
  > Will add more clarification texts in the draft

- Logistics
  > We will move the weekly meeting one hour earlier to resolve some conflicts.

Thanks,

- Xufeng

Note: Please drop me an email if you need an invite for joining the weekly call.
