2. Introduction A Yang Data Model for ACTN VN operations
This is for CMI i.e. CNC – MDSC Interface (service Model)
Support for VN views
As set of E2E tunnels (VN-Member)
As abstract topology
Support for Access Point (AP) as per the ACTN framework
MDSC translates and maps the VN request into specific network centric-models (e.g., TE-tunnels [TE-Tunnel], TE-topology [TE-TOPO], etc.) to coordinate the multi-domain network operations with PNCs.

3. Updates in this version
Support for Pre-Instantiation
VN-compute (stateless)
Support for Multi-Source and Multi-Destination
i.e. ability of MDSC to select one of the source / destination among a given set based on current conditions
In case of failure another source / destination could be selected
Others
Optional Reference to abstract topology state in [TE-Topology] and tunnel state in [TE-tunnel]
Support for Objective Functions and Metrics as per the [Info-Model].
TEAS WG, IETF Seoul

4. Pre-instantiation
RPC to take input as source, destinations, OF, metric, etc to get an output VN after computation
TEAS WG, IETF Seoul

5. Multi-source, multi-destination
Mark a source as a candidate for multi-source
Mark a destination as a candidate for multi-destination
The selected source and destination as reference to VN-member

6. Yang TREE Objective function as defined in [Info-Model] [PCEP-Yang]
Metric List
Limit
Optimize

7. Yang TREE Reference to tunnel state in [TE-tunnel] for a VN-member
TEAS WG, IETF Seoul

8. Yang TREE Reference to abstract topology in [TE-topology]

9. Next Step
Continue to enhance the VN Model to meet all requirements of ACTN
Keep align with all ACTN documents including [Info-Model]
