| 6 | CPS Overview |
| 7 | ============ |
| 8 | |
| 9 | The Configuration Persistence Service (CPS) is a platform component that is designed to serve as a |
| 10 | data repository for runtime data that needs persistence. |
| 11 | |
| 12 | Types of data that is stored: |
| 13 | |
| 14 | - **Configuration Parameters** |
| 15 | |
| 16 | These are configuration parameters that are used by xNFs during installation & commissioning. Configuration |
| 17 | parameters are typically used before the xNF has been brought up or is operational. For example, a 5G Network |
| 18 | configuration parameter for a PNFs that sets the mechanical tilt which is a configuration setting upon |
| 19 | installation. |
| 20 | |
| 21 | - **Operational Parameters** |
| 22 | |
| 23 | This operational information could be either an actual state or configuration of a network service or device. |
| 24 | These are parameters that are derived, discovered, computed that are used by xNFs during run time AFTER the |
| 25 | xNF becomes operational i.e. AFTER it has "booted up", been installed or configured. For example, in 5G Network, |
| 26 | 5G PNFs may need to adjust a tower electrical antenna tilt. These operational parameters are Exo-inventory |
| 27 | information, meaning it is information that doesn't belong in A&AI. In principle, some parameters might be both |
| 28 | configuration and operational parameters depending on how they are used. |

| 31 | -------------- |
| 32 | |
| 33 | CPS-Core |
| 34 | ######## |
| 35 | This is the component of CPS which encompasses the generic storage of Yang module data. |
| 36 | |
| 37 | **NCMP** |
| 38 | |
| 39 | The Network Configuration Management Proxy (NCMP) provides access to network configuration data and is a part of CPS-Core. |
| DylanB95EST | 3fcf869 | 2021-10-11 16:29:16 +0100 | [diff] [blame] | 40 | NCMP accesses all network Data-Model-Inventory (DMI) information via NCMP-DMI-Plugins. The ONAP0-DMI-Plugin described in the next section is one such plugin. |

| 42 | **Note:** This documentation will often refer to "CPS-NCMP" which is the component (container image) that contains both CPS-Core and NCMP since NCMP is not a stand-alone component |
| 43 | even though CPS-Core could be deployed without the NCMP extension. |

| DylanB95EST | 3fcf869 | 2021-10-11 16:29:16 +0100 | [diff] [blame] | 48 | The Data-Model-Inventory (DMI) Plugin is a rest interface used to synchronize CM-Handles data between CPS and DMI through the DMI-Plugin. |
| lukegleeson | 9249661 | 2021-09-29 11:43:34 +0100 | [diff] [blame] | 49 | This is built previously from the CPS-NF-Proxy component. |

| 54 | This service is responsible to provide a time oriented perspective for |
| 55 | operational network data. It provides features to store and retrieve sequences |
| 56 | of configurations or states along with the associated times when they occurred |
| 57 | or have been observed. |
