5 Big data - Concept and application for telecommunications

– analyzing the monitored data and providing reports on the behaviour of the resources, which can
take the form of alerts for behaviour which has a time-sensitive aspect (e.g., the occurrence of a
fault, the completion of a task), or it can take the form of aggregated forms of historical data (e.g.,
resource usage data);

– storing and retrieving monitored data and analysis reports as logging records in the RL resource
repository functional element.

A.3.7 Resource layer fault management functional element
The RL fault management functional element is responsible for fault management of the SDN-RL. It provides
capabilities for:
– detecting anomalous events which cause failure of the underlying virtual and physical resources;
– analyzing a root cause of the failure including the correlated event among virtual and physical
resources;
– generating failure resolving policies and interact with control and provisioning functional
components for the actual healing actions.

A.3.8 Resource layer performance management functional element
The RL performance management functional element is responsible for ensuring performance of the SDN-RL
resources including energy-aware resource management in the SDN-RL It provides capabilities for:
– monitoring and ensuring performance of SDN-RL physical and virtual resources based on the given
KPIs;
– estimating total energy consumption costs of underlying resources (both virtual and physical nodes
and links) with the monitored resource status information;

– calculating energy efficient optimal resource mapping based on the current estimated total energy
consumption costs and the requested KPI.

A.3.9 Resource layer security management functional element
The RL security management is an optional functional element responsible for security management of the
SDN-RL. It provides authentication and authorization capabilities of the SDN-RL and detects and avoids
anomalous attacks of the SDN-RL.
A.3.10 Resource layer resource accounting management functional element

The RL accounting management functional element is responsible for accounting management of the SDN-
RL. It provides capabilities for metering and reporting resource usage data (e.g., for charging purposes).
Resource usage data can be metered per flow or aggregated flows of virtual or physical links. Identifying
correlation information between virtual and physical flows can be performed by the virtual/physical
correlation functional element.
A.3.11 Resource layer multi-layer orchestration support functional element

The RL multi-layer orchestration support functional element provides an internal interface to the multi-layer
orchestration support functional element in the MMO functional component for requesting and receiving
management operations and associated information for multi-layer orchestration specific to the RLM.

A.4 Multi-layer management orchestration functional component

Figure A.4 shows the functional elements of the MMO functional component.
