- Define model/attributes for slice and its relationship to underlying VNF/Resources
- Design parameters needed for use by ONAP Optimization Framework (HAS) for decomposition and placement of resources needed for the slice
Design recipes/models for instantiating slices, modifying / expanding / shrinking slices, etc.
Design recipes/models for instantiating dedicated resources (e.g. AR / VR server)
Question (Stephen Terrill): what constitutes a dedicated resource? I agree we need to do this, but how to treat e.g. transport tin this context.- Create an abstracted view of the services provided by the RAN, Transport, Core network functions, and create configuration parameters for these
- Author policy definitions and their enforcement points (VNF, Controllers, DCAE / SO, etc.)
- Specify fault, performance and log data collection, Analytics, thresholds for violations, and associated corrective action
The ONAP execution framework should support the following activities.
- The Orchestrator executes the E2E Slice creation / modification recipe
- Instantiate any new VNF needed for the slice
- Pass configuration specifications, as per abstraction standards, to the RAN controller for radio slice creation, and packet core for core slice creation
- Pass QoS, bandwidth, resiliency requirements for transport network to SDN-Controller
- Configure the vEPC using App-C, orchestrated by EPC resource and service orchestration
- Start data collection and service monitoring at the relevant DCAE locations
- Track inventory/topology of slices and their states with AAI
- Collect data and perform the needed analytics about the various slices
- Trigger corrective / remedial actions for detected network impairments and service level violations
- Closed loop action initiated using SO and / or controllers
Note: ONAP also needs to be able to instantiate the required ONAP components to support the slice.

Post-Condition
The Network slice instance is operational. ONAP is actively collecting measurement information for the slice. All related Policies are deployed and active across the ONAP components.
