I.e. don't include "input" and for (2), I think that this isn't allowed. The key text being section 6.4.1 or RFC 7950 ## 4 11:20 10 Title: Yang model update > Draft: > https://tools.ietf.org/html/draft-ietf-teas-te-service-mapping-yang-04 > https://tools.ietf.org/html/draft-ietf-teas-actn-pm-telemetry-autonomics-03 > https://tools.ietf.org/html/draft-ietf-teas-actn-vn-yang-09 > Presenter: Dhruv Dhody Tarek Saad: Is the path computed by "template" in TE-Service mapping, stateful in nature? Dhruv Dhody: This is just the constraints and optimization criteria and nothing to do with the statefulness of path. Daniele Ceccarelli: This comes from the OSS layer, which doesn't care about how it is provided via te tunnels, just that the service characteristics are met ## 5 11:30 10 Title: DT Intro, IETF Definition of Transport Slice > Draft: > https://tools.ietf.org/html/draft-nsdt-teas-transport-slice-definition-03 > Presenter: Jari Arkko + Reza Rokui Actual Start Time: 11:42 Lou Berger: Expect an adoption call on the list. ## 6 11:40 10 Title: Framework for Transport Network Slices > Draft: > https://tools.ietf.org/html/draft-nsdt-teas-ns-framework-04 > Presenter:Eric Gray > Actual Start Time: 11:53 Daniele Ceccarelli: in ACTN we have defined the interface between MDSC and CNC as a boundary between a customer and the operator. We are now lacking of a reference point between the MDSC and another entity within the operator. We have identified a similar issue in the context of POI. On the MDSC role, I agree with the interpretation. Lou Berger: Any objections to adoption? <none></none> Please expect an adoption call on list. ## 7 11:50 10 Title: Transport Network Slice YANG Data Model > Draft: https://tools.ietf.org/html/draft-liu-teas-transport-network-slice-yang-01 > Presenter: Xufeng Liu Actual Start time: 12:10 ## 8 12:00 10 Title: A Yang Data Model for Transport Slice NBI > Draft: > https://tools.ietf.org/html/draft-wd-teas-transport-slice-yang-02 > Presenter: Bo Wu Actual Start Time: 12:18 (From Jabber) Vishnu Beeram: Note that the previous presentation ties the modeling of a transport network slice to existing network topology models while the current presentation focuses on the service view of a slice. Please chime in with your views on these 2 approaches (either here or on the list).. There seems to be a case being made (by both sets of authors) to make room for both -- please discuss if you have any objections... Lou Berger: Please take comments/discussion to list ## 9 12:10 10 Title: Network Slicing with Flexible Traffic Engineering > Draft: https://tools.ietf.org/html/draft-zzhang-teas-network-slicing-with-flex-te-00 > Presenter: Jeffrey Zhang Actual Start Time: 12:26 Please take comments/discussion to list ## 10 12:20 10 Title: Packet Network Slicing using Segment Routing > Draft: https://tools.ietf.org/html/draft-peng-teas-network-slicing-03 > Presenter: Ran Chen Actual Start Time: 12:31 Please take comments/discussion to list ## 11 12:30 10 Title: A YANG Data Model for MPLS-TE Topology > Draft: https://tools.ietf.org/html/draft-busizheng-teas-yang-te-mpls-topology-00 > Presenter: Italo Busi > Actual Start Time: 12:36 Please take comments/discussion to list ## Adjourn 12:40 >
