ITU-T Focus Group IMT-2020 Deliverables 3

• storing and providing APIs for query the contents generated by the VDPR-RMA

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

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

Virtual/Physical Correlation
The Virtual/Physical Correlation (VPC) functional element is responsible for correlating the relationship
between virtual and physical resources in RP and provides the following capabilities for:
• identifying correlation information among virtual and physical resources in the underlying IMT-2020
networks for efficient provisioning, performance monitoring and fault detection and root-cause
analysis
• identifying correlation information between virtual and physical flows for charging purpose

• storing correlation information in a common resource information repository and providing
programming interfaces to other functional components which need correlation information

Virtual Data Plane & Resource Monitoring and Analytics

The Virtual Data Plane & Resource Monitoring and Analytics (VDPR-MA) functional element is responsible for
collecting the status and events of virtual data plane & resources and analyzing them for the purpose of
FCAPS and provides capabilities for:
• monitoring the activities, status, anomalous events of the virtual data plane & resources in the
underlying IMT-2020 networks
• analyzing the monitored data and providing reports on the behavior of the 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 Virtual Data
Plane & Resource Repository functional element.
Virtual Data Plane & Resource fault management

The Virtual Data Plane & Resource Fault Management (VDPR-FM) functional element is responsible for fault
management of the VDPR and provides capabilities for:
• detecting anomalous events which cause failure of the underlying virtual data plane & resources.
• analyzing a root cause of the failure including the correlated event among virtual data plane &
resources
• generating failure resolving policies and interact with control and provisioning functional
components for the actual healing actions.

Virtual Data Plane & Resource Performance Management

The Virtual Data Plane & Resource Performance Management (VDPR-PM) functional element is responsible
for ensuring performance of the virtual data plane & resources including energy-aware resource
management and provides capabilities for:
• monitoring and ensuring performance of the virtual data plane & resources based on the given KPIs
