Physical Data Plane & Resource Performance Management

The Physical Data Plane & Resource Performance Management (PDPR-PM) functional element is responsible
for ensuring performance of the physical data plane & resources including energy-aware data plane &
resource management and provides capabilities for:
• monitoring and ensuring performance of the physical data plane & resources based on the given
KPIs
• estimating total energy consumption costs of underlying physical data plane & resources (physical
nodes and links) with the monitored data plane & resource status information
• Calculating energy efficient optimal data plane & resource mapping based on the current estimated
total energy consumption costs and the requested KPI
Physical Data Plane & Resource Security Management functional element

The Physical Data Plane & Resource Security Management (PDPR-SM) functional element is an optional
functional element responsible for security management of physical data plane & resources and provides
authentication and authorization capabilities and detecting and avoiding anomalous attacks of physical data
plane & resources.

Physical Data Plane & Resource Charging Management
The Physical Data Plane & Resource Charging Management (PDPR-CM) functional element is responsible for
accounting management of physical data plane & resources and provides capabilities for:
• metering and reporting data plane & resource usage data for charging. Data Plane & Resource usage
data can be metered per flow or aggregated flows of physical links
Physical Data Plane & Resource Multi-Plane Management Orchestration Support

The Physical Data Plane & Resource Multi-Plane Management Orchestration Support (PDPR-MMOS)
functional element provides an internal interface to the Multi-Plane Orchestration support functional
element in the MMOS functional component for requesting and receiving management operations and
associated information for multi-layer orchestration specific to resource layer management.

8.2 Virtual Data Plane & Resource Management Functional Component
Virtual Data Plane & Resource Management (VDPRM) functional component manages virtual infrastructure
data plane and resources. Management of virtual data plane and resource function packages supports
subsequent instantiation of a virtual data plane and resource function and validation. Instantiation of VDPRM
is managed based on present mandatory virtual infrastructure information. Validation and authorization of
virtual infrastructure resource is handled in response to network service request. Virtual infrastructure
resource is managed across operator’s infrastructure domain including distribution, reservation, and
allocation for network service instances and VDPRM instances. It also collects usage information of virtual
infrastructure resources and forward required information for update.
This sub-clause describes detailed management functionality in the VDPRM. Figure 8 shows its functional
elements.
