7.4.1 Resource layer management functional component
The RLM functional component is responsible for the management of physical and/or virtual resources in the
SDN-RL. The RLM functional component provides capabilities for discovering and activation of virtual and
physical resources to make them ready for operation. The RLM functional component includes support for
FCAPS and SDN-RL orchestration (e.g., coordinated resource reconfiguration) that is provided by the MMO
functional component. The MMO functional component provides the capabilities for provisioning of SDN-RL
resources and the RLM functional component keeps track of the overall state of allocated and available
resources in the SDN-RL.

The RLM functional component is also responsible for managing the configuration relationship between
virtual and physical resources (e.g., interface ID mapping between virtual and physical resources),
performance correlation between virtual and physical resources, and faults by considering the relationship
between virtual and physical resources, and finally isolation and control of any anomaly concerning SDN
network resources, as well as authentication and authorization of the network resources.

By providing the overall resource status information monitored as an input to the RLM functional component,
energy efficient resource management capability and other management capabilities can be realized by e.g.,
turning off of unused resources.

7.4.2 Control layer management functional component
The CLM functional component includes management of resources used to deploy SDN-CL functions
(hardware, software platforms, links connecting control plane with other planes) in order to ensure high
availability and scalability of the SDN-CL, performance, fault and security management of control traffic
generated between SDN-CL entities and SDN-RL or SDN-AL entities. It can activate SDN-CL entities or their
components, monitor performance of SDN-CL entities in terms of reliability, utilization, detection, root cause
analysis, and correction of faults of the SDN-CL: detection, isolation, and control of SDN-CL related traffic and
authentication and authorization management functionality of SDN-CL entities. Policy management can
include business, technical, security, privacy and certification policies that apply to CL services and their usage
by SDN applications.
The CLM functional component can also provide energy-aware CL resource management. Mechanisms used
by the RL energy-aware resource management can be applied in the CL as well.
