8.1 Physical Data Plane & Resource Management Functional Component

Physical Data Plane & Resource Management Functional Component manages physical data plane and
resources including compute, storage, and configuration. It provides complete visibility into the physical state
of the data plane and resource at any given time. Handling many devices is achieved providing both device-
centered perspective and network-wide perspective. Connectivity is established over the physical data plane
and resource through its management. All device accesses pass through physical data plane and resource
management such that access and catalogue real-time status information about physical layer data plane
and resource is available at all times. The state of every physical Data Plane & Resource connection is
reported whether or not it is connected, how much bandwidth it can carry and the type with corresponding
mapping and alarming. It manages the entire physical layer, mapping routes, issuing work orders, reserving
available ports, reporting on flow/path information and other physical functions.
This sub-clause describes detailed management functionality in the Physical Data Plane & Resource
Management (PDPRM) functional components. Figure 7 shows its functional components.

Physical Data Plane & Resource Support
The Physical Data Plane & Resource Support (PDPR-S) functional element provides a standard interface to
the PDPR Management Support and Softwarization in the Resource Plane for requesting and receiving
management operations and associated information in ASP.
