2. 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.);

3. 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:
This draft captures some key information;

4. 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.

6. 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;
