Application and Service Plane Multi-Plane Management Orchestration Support

The Application and Service Plane Multi-Plane Management Orchestration Support (ASP-MMOS) functional
element provides an internal interface to the Multi-Plane Management Orchestration Support functional
element in the IMT-2020-MP for requesting and receiving management operations and associated
information for multi-plane management orchestration specific to application layer management.

8.5 Multi-Plane Management Orchestration and Slice Lifecycle Management Support Functional
Component
Orchestrator manages automated arrangement, coordination, and management of both physical and virtual
network, control and service resources. Physical and virtual network resources are orchestrated in a manner
best suited to match the network constraints specified by other management plane components. Dynamic
resource selection is determined based on the current physical and virtual network management status
information. It ensures optimized allocation of the necessary resources and connectivity for the best suited
service information from service management. Based on resource availability and load, it coordinates related
resources to assure the network management direction. Therefore, it plays the key role in management plane
for IMT-2020.
This sub-clause describes detailed management functionality in the Multi-Plane Management Orchestration
and Slice Lifecycle Management (MMO-SLM) functional component. Figure 11 shows its functional elements.

Multi-Plane Management Orchestration Support

The Multi-Plane Management Orchestration Support (MMOS) functional element provides an internal
interface to the Multi-Plane Orchestration Support functional element in the ASPM, CPM, RPM functional
components for requesting and receiving management operations and associated information for multi-layer
orchestration.
Virtual/Physical Resource Management Orchestration

The Virtual/Physical Resource Management Orchestration (VPR-MO) functional element provides
orchestration of the coordinated virtual and physical resources provisioning and configuration.

Multi-Plane Management Functions Orchestration
The Multi-Plane Management Functions Orchestration (MMFO) functional element provides functionality for
supporting the lifecycle management of IMT-2020 application/network services across the entire IMT-2020
