Physical Data Plane & Resource Plane Resource Discovery and Bootstrapping

The Physical Data Plane & Resource Discovery and Bootstrapping (PDPR-DB) functional element is
responsible for discovering and bootstrapping physical Data Plane & resources and provides capabilities for:
• discovering technology specific physical data plane & resources. The discovered resources are
stored in the PDPR resource repository. Note that control layer is responsible for abstract resource
discovery which is common across any underlying heterogeneous technology specific physical data
plane & resources.
• bootstrapping of physical data plane & resources to make them ready for operation based on the
bootstrapping policies.

Physical Data Plane & Resource Repository

The Physical Data Plane & Resource Repository (PDPR-R) functional element is responsible for storing the
contents discovered by the PDPR-DB and managing the lifecycle of the contents in the repository and
provides capabilities for:
• storing and providing APIs for query the contents discovered by the PDPR-DB
• storing and providing APIs for query the contents generated by the PDPR-RMA

• Lifecycle management of the contents in the repository (e.g., creation by storing, modification,
deletion, etc.)

Physical Data Abstraction
The Physical Data Abstraction (PDA) is responsible for generating abstractions of technology specific physical
resources into technology independent common information and provides capabilities for:
• converting device dependent resource data into independent abstracted information
• storing abstracted information in PDPR-R and providing APIs to other functional components which
need abstraction information

Physical Data Plane & Resource Monitoring and Analytics
The Physical Data Plane & Resource Monitoring and Analytics (PDPR-MA) functional element is responsible
for collecting the status and events of physical Data Plane & resources and analyzing them for the purpose
of FCAPS and provides capabilities for:

• monitoring the activities, status, anomalous events of the physical data plane & resources in the
underlying IMT-2020 networks
• analyzing the monitored data and providing reports on the behavior of the data plane & resources,
which can take the form of alerts for behavior which has a time-sensitive aspect (e.g., the occurrence
of a fault, the completion of a task), or it can take the form of aggregated forms of historical data
(e.g., resource usage data)
• storing and retrieving monitored data and analysis reports as logging records in the Physical Data
Plane & Resource Repository functional element.

Physical Data Plane & Resource Fault Management
The Physical Data Plane & Resource Fault Management (PDPR-FM) functional element is responsible for fault
management of the PDPR and provides capabilities for:
• detecting anomalous events which cause failure of the underlying physical data plane & resources.

• analyzing a root cause of the failure including the correlated event among physical data plane &
resources
• generating failure resolving policies and interact with control and provisioning functional
components for the actual healing actions.
