Scott Mansfield: Liaison response to JCA will be reviewed in April
meeting.
Oscar Gonzalez de Dios: ETSI liaison will be discussed in teas.

1 09:43 15 Title: A YANG Data Model for Optical Impairment-aware
Topology
Draft:
https://datatracker.ietf.org/doc/draft-ietf-ccamp-optical-impairment-topology-yang

Draft: https://datatracker.ietf.org/doc/draft-ietf-ccamp-rfc9093-bis/
Presenter: Sergio Belotti (Remote)
Daniele: We will take the action to YANG Doctor Review for
impairment draft.

2 10:04 10 Title: Framework and Data Model for OTN Network Slicing
Draft:
https://datatracker.ietf.org/doc/draft-ietf-ccamp-yang-otn-slicing/
Presenter: Aihua Guo
Daniele Ceccarelli: (for model dependency) Option 1 is preferred.
Bo Wu: Network Slice framework only talks SDP so far without
including node/link defined in this Network Slice Topology, more
discussion & clarification is needed.
Aihua Guo : Okay.

3 10:13 20 Title: Update on Flexi-Grid drafts
Draft:
https://datatracker.ietf.org/doc/html/draft-ietf-ccamp-flexigrid-yang
Draft:
https://datatracker.ietf.org/doc/draft-ietf-ccamp-flexigrid-tunnel-yang/

Presenter: Daniel King
Dan King: Hair lost during Flexi-grid work:)
Aihua Guo: the changes introduced now is due to additional use cases
from multiple implementers.
Dan King: We do have operators help work on multi-tech, and we want
to align with the WG for future proof.
Daniele Ceccarelli: Please send a mail to the list, for better
advertisment, to announce the benefits. Request may be copied to other
relevant WGs (e.g. TEAS) to solicit comments.

4 10:31 10 Title: Update on Microwave Topology YANG Model
Draft: https://datatracker.ietf.org/doc/draft-ietf-ccamp-mw-topo-yang/
Draft:
https://datatracker.ietf.org/doc/draft-ietf-ccamp-if-ref-topo-yang/
Draft: https://datatracker.ietf.org/doc/draft-ietf-ccamp-bwa-topo-yang/

Presenter: Scott Mansfield
Bo Wu: Any consideration on schema amount?
Scott Mansfield: Evaluated but may not work well, Open to that.
Daniele Ceccarelli: How can the microwave topology YANG model be
independent from the two other drafts?
Scott Mansfield: They follow: Microwave -> TE-> Network
augmentation.
Daniele Ceccarelli: the next question is whether the generic part
fits into ccamp, probably netmod or other better home?
Robert Wilton: Keen to see the work done. Please notify the netmod
meeting (send email to chairs) and see their feedback, will bring it to
Netmod on Friday.
Daniele Ceccarelli: we can continue working, and decide in the next
meeting.
Robert Wilton: recommend the schema amount for model reference,
please feel free to report problem to netmod.
Oscar Gonzalez de Dios: generic part can be brought to opsawg as
well.

5 10:41 10 Title: A YANG Data Model for Network Inventory
Draft:
https://datatracker.ietf.org/doc/draft-ietf-ccamp-network-inventory-yang/

Presenter: Italo Busi
Daniele Ceccarelli: the geo info looks sensitive, security please
emphasize.
Daniele Ceccarelli: please be aware of the inventory-yang mailing
list for cross-WG coordination. A short WG may be created (NIMBY), the
current progress is people are preparing the charter. It will belong to
the OPSAWG.
Robert Wilton: will bring the proposal to IESG on Friday.
Nigel Davis: clarifying not using topo RFC8345 is reasonable? (to
check offline).

6 10:51 5 Title: DWDM Interface Parameter YANG
Draft:
https://datatracker.ietf.org/doc/draft-ietf-ccamp-dwdm-if-param-yang/
Presenter: Gabriele Galimberti (Remote)
No discussion.

7 10:56 7 Title: ACTN POI
Draft:
https://datatracker.ietf.org/doc/html/draft-poidt-ccamp-actn-poi-pluggable/

Presenter: Gabriele Galimberti (Remote)
Yi Lin: More options (e.g. channelized OTN) besides the wavelength
on routers, could be more generalized.
Gabriele Galimberti: can be done.
Oscar Gonzalez de Dios: multi-layer management should be
investigated, separate from IP over OTN. Try to involve more operators.

8 11:07 7 Title: A YANG Data Model for Optical Network Performance
Monitoring
Draft:
https://datatracker.ietf.org/doc/draft-yu-performance-monitoring-yang/
Presenter: Chaode Yu
Oscar Gonzalez de Dios: is it optical specific?
Chaode Yu: prefer to be optical-specific even though the current
data model contains some generic features.
Nigel Davis: T-API worked on similar issues, identity & string, can
be referenced in this work as well.
Dieter Beller: reference to data planes (ITU-T) will be useful, will
send the reference to mailing list.

9 11:17 7 Title: Performance Monitoring for Client Signals
Draft:
https://datatracker.ietf.org/doc/draft-zheng-ccamp-client-pm-yang/
Presenter: Haomian Zheng

Wu Bo: The module name is ietf-service-pm which is quite confusing.

Haomian Zheng: We will fix that.

poll has shown interest in moving forward this work: to be confirmed on
the mailing list

Daniele Ceccarelli: The last two drafts belong to other WGs (OPSAWG
and TEAS WG) and they are presented as an heads-up to CCAMP WG

10 11:23 7 Title: Incident Management
Draft:
https://datatracker.ietf.org/doc/draft-feng-opsawg-incident-management/

Presenter: Chaode Yu

be in the ccamp.

11 11:28 7 Title: IETF Network Slice Topology YANG Data Model
