ELEMENT SYNC - Software keeps the A&AI elements with the elements in the RunTime DB in Sync.
- A&AI - A&AI is still the master of valid entities in the network and provides a dynamic view of the assets (xNFs) available to ONAP
- CPS (xNF Proxy) - The CPS is the owner (within ONAP) of the associate (exo-inventory) data associated with the xNFs.
- DYNAMIC VIEW - When a xNF appears or is removed from the system, CPS records will be added/removed based on A&AI entries.
3.1 Concepts
A dataspace is a logical separation of data within the CPS. Dataspaces are specified by data owners.
An anchor is a logical separation of data instances compliant to the same model (set of YANG modules). Anchors are created by data owners.
Anchors and dataspaces are described here
An owner is an ONAP component that is responsible for data in the CPS. Responsibility includes deciding how data is exposed to other ONAP components. Options being:
- Data is exposed via µService APIs – no direct access to data via CPS interfaces
- Data is exposed via CPS interfaces – requires registration/discovery and access control to be implemented (FUTURE)
