YANG Models for the Northbound Interface of a Transport Network Controller: Requirements and Gap Analysis CCAMP WG, IET97, Seoul draft-zhang-ccamp-transport-yang-gap-analysis-01.txt Xian ZHANG (zhang.xian@huawei.com) Anurag Sharma (ansharma@infinera.com) Sergio Belotti (sergio.belotti.nokia.com) Tara Cummings (tara.cummings@ericsson.com) And Ruiquan JING from China Telecom, Yan SHI from China Unicom, Jeong-dong Ryoo from ETRI, Daniel King from Lancaster Univ. , Yubin Xu from CAICT

Objective and Scope Goal: Non-Goal: focuses on analyzing existing models that can be used by the domain controller and the orchestrator for various use cases identified in transport/TE networks; use cases: single-domain network, multi-domain network, multi-layer network, etc. to identify any modeling gaps (any model missing, any attributes missing in existing models) and providing a sort of guideline both for possible augmentation of existing models or new Yang models; Non-Goal: Controller-device interface protocol(s) (PCEP, NETCONF etc.);

Related Activities and Status Finished single-domain before IETF96; Provided first bunch of comments to TE tunnel model; Submitted otn tunnel model; Finished multi-domain, multi-layer cases before IETF97; Provided second set of comments to TE tunnel model; Held joint discussion with TE Topology authors on multi-layer case; Information and materials available at: https://github.com/TransportModels/IETF-Transport-Modeling This draft captures some key information;

Updates in Version 01 Added references to the github for more detailed materials; Updated the section for multi-layer descriptions; Updated the summary table to point to specific YANG models; Updated to include the discussions related to transitional links for multi-layer description and ongoing path computation discussions.

Next Step Comments? Next-step Plan: Serving as a starting point for CCAMP design team(?); Following different topic on discussion (e.g.path comp.) and help solving relative possible issues; keep on updating to include more information if necessary;
