Design Team’s Goals and Deliverables:

– Develop use cases and gap analysis

Identjfy a set of technologies use cases and providing a gap analysis against

existjng models

– Identjfy missing models or capability – Coordinate requirements with appropriate WGs

Including TEAS, RTGWG and CCAMP itself

– Providing guidelines in terms of how all the related models can be used in a step-wise manner

Using a couple of well identjfjed transport network use cases
Working methods

– Mailing lists & Conference calls – GitHub: htups://github.com/danielkinguk/transport-nbi

Applicability Statement Updates

Major updates since IETF 103

– Agreed defjnitjon of “Domain” – Further describes the control of access links which support difgerent technology confjguratjon (e.g., STM-64, 10GE or OTU2) depending on the type of service – Completed Ethernet service and topology descriptjon – Updated “Protectjon and Restoratjon Confjguratjon” sectjon – Improved overall readability – drafu-ietg-ccamp-transport-nbi-app-statement-05

Next Steps

Document has a number of enhancements queued

– htups://github.com/danielkinguk/transport-nbi/issues – Editors, authors and contributors need to agree which are useful, nice to have, unnecessary

Face-to-face DT meetjng planned during IETF 104

– Review open issues and enhancements – Wednesday 13:30-15:00 (Karlin 1/2)

Submit for Last Call in June
