R7 COMPONENT DESCRIPTION

ARC Configuration & Persistency Service (CnPS) Component Description - Guilin (R7) Release

BUSINESS DRIVER

EXECUTIVE SUMMARY - The Data Persistency Service is a new platform component that is designed to serve as a data repository for Run-time data that needs to be persistent. As a stand-alone ONAP component, this project provides data layer services to other ONAP platform components and use cases that require persistent configuration or operational data. The R6 development will be enhanced as well.      

BUSINESS IMPACT - The ability for service operators to visualize and manage data in a RAN network (PNFs, VNFs, and logical constructs) with ONAP is a critical business function because they are key Life Cycle Management (LCM) and OA&M operations. The project has business impacts to enhance the operation of data-handling within ONAP by providing efficient data layer services.

BUSINESS MARKETS - This project applies to any domain (wireless, transport, optical, and wireline) that ONAP may manage. It is not a market or geographical specific capability. It is expected that scaled ONAP installations such as Edge & Core ONAP deployments will also deploy the database across each installation.

FUNDING/FINANCIAL IMPACTS - This project represents a large potential Operating Expense (OPEX) savings for operators because of the ability to configure networks saving time and expenses.

ORGANIZATION MGMT, SALES STRATEGIES - There is no additional organizational management or sales strategies for this use case outside of a service providers "normal" ONAP deployment and its attendant organizational resources from a service provider.



ROADMAP

The roadmap for CPS and what will be delivered in the upcoming releases:

Updated C&PS ROADMAP Jun 26, 2020 

C&PS 1.0 - This is the evolution of ConfigDB in the CC-SDK / SDN-C. this solution was initially coded in R3 for the OOF/SON/PCI Use Case and was referred to as "ConfigDB" using a MariaDB ITDM solution. Because in R7 GuiLin planning, there is some clarity needed to identify the different tracks of development, the notation is introduced here, "C&PS 1.0" to allow people to have a common "language" to refer to a body of work. This was done in the R6 time frame.

C&PS 1.1 - This is the continuation of the C&PS 1.0 solution (see above). Updates will involve schema and interface changes for additional data supported in the C&PS database. This will be introduced in the R7 Guilin time frame. Thus, when someone refers to C&PS, in the R7 time frame they are referring to the C&PS 1.1 solution. Additionally, there are two C&PS related PoC going on the Model-Driven C&PS and State Management PoC (Bell Canada) and when referring to R7 C&PS, work done in these PoC are also included.

C&PS 2.0 - C&PS 2.0 is the stand-alone project. In R8 Honolulu, the goal is to have C&PS become its own stand-alone project. Thus, a presentation to the Architecture S/C and TSC will be made again to petition for a stand-alone project.

Description

Configuration Persistence Service is a platform component that is designed to serve as a data repository for Run time data that needs to be persistent. It is characterized by the following.

    DATA REPOSITORY -  The types of data that is stored in the Run-Time data storage repository for:

  1.    CONFIGURATION PARAMETERS - These are configuration parameters that are used by xNFs during PnP, installation, commissioning.

  2.    OPERATIONAL PARAMETERS - These are parameters that are derived, discovered, computed that are used by xNFs during run time AFTER the xNF becomes operational i.e. AFTER it has "booted up", been installed, configured. These operational parameters are Exo-inventory information, meaning it is information that doesn't belong in A&AI.

  3.    NETWORK ELEMENT POLICY INFORMATION - NE policy type information used by micro-service.

  4.    APPLICATION INFORMATION - Information related to operational parameter.

    DATA LAKE - Architecturally, the Configuration Persistence Service is designed to be a common services data layer which can serve as a data lake to other run time entities (ONAP components or external tools).

    C&PS FUNCTIONS - The Configuration Persistence Service enables functionality to be performed by other entities. It will ENABLE the capability of another components or external tools within/or external to ONAP to perform the functions.

  •         CONFIGURATION MANAGEMENT FUNCTIONS - Enables OSS configuration, optimization, and LCM operations.

  •         SYNCING - The Configuration Persistence Service enables the ability to sync data between initial and delta changes ONAP & the xNFs.

  •         DATA RECOVERY - It will allow for the recovery of data once a source of truth is defined.

  •         UPDATES - It will allow for updates, delta changes, and incremental updates to be performed.

  •         DATA HISTORY - See a history of changes in data including versioning of the data, updates, roll back, restoration, and time series management.

  •         AUDITING - Auditing of parameters against a "golden" template. It itself stores & provides the data for auditing. Consistency checks.

  •         ROLL BACK - It will allow for rollback back of entire DB to "save points" or recovery points.

  •         RESTORATION - It will allow for the recovery and restoration of data records to a fall back point.

  •         ACCESS CONTROL - A security topic, which allows the definition of policies, of who and what they can update.

  •         TOPOLOGY TRAVERSAL - It will enable the ability for something to traverse the relationship between data elements.

  •         MODEL ADAPTION - Allows for the adaptation or transformation of models from other sources (e.g. ORAN or 3GPP models).
