A.3.1 Resource layer support functional element

The RL support functional element provides a MMR reference point to the RL-MS functional component (see
clause 7.3.4) which is used for requesting and receiving management operations and associated information
from/to the SDN-AL.

A.3.2 Resource layer resource discovery and bootstrapping functional element
The RL resource discovery and bootstrapping functional element is responsible for discovering and bootstrapping
physical and virtual resources in the SDN-RL. It provides capabilities for:
– discovering technology specific physical and virtual resources. The discovered resources are stored
in the RL resource repository functional element. The SDN-CL is responsible for abstract resource
discovery which is common across any underlying heterogeneous technology specific physical and
virtual resources;
– bootstrapping of physical and virtual resources to make them ready for operation based on the
bootstrapping policies.

A.3.3 Resource layer resource repository functional element
The RL resource repository functional element is responsible for storing the contents discovered by the
resource discovery and bootstrapping and managing the lifecycle of the contents in the repository. It provides
capabilities for:
– storing and providing APIs for querying the contents discovered by the RL resource discovery and
bootstrapping functional element;

– storing and providing APIs for querying the contents generated by the RL resource monitoring and
analytics functional element:
– ensuring lifecycle management of the contents in the repository (e.g., creation by storing,
modification, deletion).

A.3.4 Data/information abstraction functional element
The data/information abstraction functional element is responsible for generating abstractions of technology
specific physical and virtual resources in the SN-RL into technology independent common information. It
provides capabilities for:
– converting device dependent resource data into independent abstracted information;
– storing abstracted information in RL resource repository functional element;
– providing APIs to other functional components which need abstraction information.

A.3.5 Virtual/physical correlation functional element
The virtual/physical correlation functional element is responsible for correlating the relationship between
virtual and physical resources in RL and provides the following capabilities for:
– identifying correlation information among virtual and physical resources in the underlying SDN
networks for efficient provisioning, performance monitoring and fault detection and root-cause
analysis;
– identifying correlation information between virtual and physical flows for accounting purpose;

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

A.3.6 Resource layer resource monitoring and analytics functional element

The RL resource monitoring and analytics functional element is responsible for collecting the status and
events of SDN-RL resources and analyzing them for the purpose of FCAPS management. It provides
capabilities for:
– monitoring the activities, status, anomalous events of the virtual and physical resources in the
SDN-RL;
