Presentation Start Time Duration Information

0 13:00 15 Title: Administrivia - WG Status - Reporting on WG drafts not
being presented - Milestones Update - Charter Update

                 Presenter:        Chairs Gabriele Galimberti (draft-ietf-dwdm-if-lmp): No updates (draft-ietf-ccamp-dwdm-if-param-yang) : Also no updates, see dependencies to a few works include layer0-types.  Scott Mansfield (from chat): the two drafts carved out of MW topology will be progressed between now and Prague, now that MW topology is almost done. Daniel King: (draft-ietf-transport-nbi-app-statement): the updates captured changes in content/references.  (T-NBI design team): we are updating the charter and members, side meeting is scheduled tomorrow, to align the objectives. Objectives include not only the draft but also create the guidelines to use ccamp models, to be published as wiki.  Daniele Ceccarelli: the design team is going to have a separate mailing list. (what John said?)

1 13:15 20 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 (discussion during the impairment draft, 13:26) Daniel Ceccarelli: anything need to be added towards new applications (e.g., pluggable)? Sergio Belotti: the model is already there and suppose to work in new scenarios.  Daniele Ceccarelli: aligned with my understanding. Please authors include these applicabilities considerations and we can move forward.

2 13:36 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: any chances that ietf-network-slice-topology is not going to be adopted? It seems to be needed for many applications. Aihua Guo: Yes, that's what we think. Discussion in TEAS has raised a lot of comments. Need to work out how much ability we give the customer to customised the connection types and the topology. Daniele Ceccarelli: in any case, the topology will be used as read-write or read-only for provisioning only?  Aihua Guo: it depends on the scenario and user's demand, technically both works.  Daniele Ceccarelli: let's check the teas progress, we do expect teas to adopt that work.

3 13:45 10 Title: A YANG Data Model for Flexi-Grid Optical Networks

                 Draft:       https://datatracker.ietf.org/doc/html/draft-ietf-ccamp-flexigrid-yang

                  Presenter:        Daniel King (Remote) Adrian Farrel: Regarding te-link-bandwidth, is it teas concept? Probably the guideline should be coordinated with teas work and announced jointly as well.  Daniel King: Yes a valid comment. This is already some concensus and we can update the TE tutorial.  Aihua Guo: a follow up regarding TE tunnels and WSON/Flexi-grid. Once we have multi-tech single-instance topology it could allow people to set up tunnel across multi-layers. These would be important when we commonly design the WSON/Flexi-grid tunnel. Path computation is the same.  Daniel King: Great point. From operator's perspective the less amount of state that needs to be modeled and maintained is always good, to reduce the cost on operation.  Daniele Ceccarelli: How to document the guideline would need discussions. It may impact the publication of RFC if we have other document to be published. Pointing to an unpublished document will be push back. We are considering using Wiki as well.

4 14:03 15 Title: Update on Microwave Topology YANG Model

                 Draft:       https://datatracker.ietf.org/doc/draft-ietf-ccamp-mw-topo-yang/ No Discussion.

                  Presenter: Italo Busi

5 14:10 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: Would it be useful to add a parameter to say whether
it was manually introduced (provisioned)?
Italo Busi: Yes. Currently structured so that discovered and configured
are in different parts of the tree.

7 14:17 10 Title: Integrating YANG Configuration and Management into an
Abstraction and Control of TE Networks (ACTN) System for Optical
Networks
TAKEN OUT OF ORDER

                 Draft:       https://datatracker.ietf.org/doc/draft-gstk-ccamp-actn-optical-transport-mgmt/

                 Presenter:        Daniel King (Remote) Luis Contreras: clarify the FCAPS info collected from PNC or MDSC?  Daniel King: Applies in both scenario, The MDSC will have end-to-end requirements, the PNC will have device/domain specfic requirements. The OSS may manage a PNC via a NMS to EMS (legacy), or MDSC may talk to a controller. Communication and models we are inetersted in are below the MDSC.  Luis Contreras: in deployment the optical and packet may have different OSS.  Daniel King: true. Coordination is required, sometimes a NMS might coordinate across EMS's, or you may have to operate each EMS in isolation.  Daniele Ceccarelli: Relationship consideration. Assurance work done in teas? This work is a tech-specific to that one?  Daniel King: I think this can feed into the TEAS POI service assurance, its complimentary not competition.  Adrian Farrel: we need bigger map. This is clearly below MDSC. Another work may relate would be incident. The other piece would be non-optical. We do need coordinate with packet people for packet-specific parameters (such as ippm).  Oscar Gonzalez de Dios: align with opsawg would be needed. Not sure how related with assurances. The design could be completely decoupled or somehow joint.  Italo Busi: ACTN POI assurance is more focusing on multi-layer collaboration, and should be considered as complementary with this work.  Daniele Ceccarelli: please include the explicit relationship in the draft.

6 14:35 15 Title: ACTN POI Pluggable

                 Draft:       https://datatracker.ietf.org/doc/html/draft-poidt-ccamp-actn-poi-pluggable/

                 Presenter: Oscar Gonzales de Dios Reza Rokui: option 1, there is no either or relationship here, both need to work together. Need to be careful who is looking at the end-to-end services. Lots of details need to be clear, which entities are responsible for configuration, provisioning and diagnosis. Aihua Guo: For the time being, IP PNC managing optical is awkward. Any consideration besides netconf/yang? For example protocol?  Oscar Gonzalez de Dios: preferring netconf/YANG but see some protocol work Daniele Ceccarelli: any info about protocol so far? Oscar Gonzalez de Dios: Protocol needs to have inter-op among multiple pieces and also have similar problem.  Luis Contreras: organizing poll.  (poll result shows half-half on this work, will take to the list)

8 14:55 10 Title: A YANG Data Model for Optical Network Performance
Monitoring

                   Draft:       https://datatracker.ietf.org/doc/draft-yu-performance-monitoring-yang/

                 Presenter:        Aihua Guo No Discussion.

9 15:02 5 Title: Architecture for control of photonic plugs in devices
with packet functions

                   Draft:       https://datatracker.ietf.org/doc/draft-davis-ccamp-photonic-plug-control-arch/

                 Presenter:        Nigel Davis Daniele Ceccarelli: this work is related with previous POI, and willing to see further discussion.
