5 Big data - Concept and application for telecommunications

The ERM functional component provides management functionality to interwork with external management
entities. External management entities can be a legacy OSS/BSS, management and orchestration entities [b-
MANO], cloud management entities, or other management functionality which can be defined in the future.
The ERM functional component plays a role of the representative interface of SDN management toward the
external management entities. Its main functionality includes abstraction of SDN management information
for the exchange and request/reply of management operations with external management entities. It can be
used for policy management, data analytics, accounting, etc.

The ERM functional component is also responsible for MMF to interact with an external DevOps system to
enable efficient development of SDN functionality by providing developer environment setup processes,
build and test management, and deployment.

A.5.1 External management interworking support functional element
The external management interworking support functional element provides an MMFO reference point to
OSS/BSS for requesting and receiving management operations and associated information to/from OSS/BSS.

A.5.2 Management information abstraction functional element
The management information abstraction functional element provides abstraction of SDN management
information for the exchange with external management entities for inter-domain management information
hiding purpose.

A.5.3 Request/reply with external management functional element

The request/reply with external management functional element provides functionality associated with
request/reply management operations with external management entities.

A.5.4 External SDN policy management functional element
The external SDN policy management functional element provides external SDN policy exchanges involved
between MMF and external management entities, data analytics, accounting, and interaction with an
external DevOps system to enable efficient development of SDN functionality by providing developer
environment setup processes, build and test management, and deployment.

A.5.5 Multi-layer management orchestration support functional element
The multi-layer management orchestration support functional element provides an internal interface to the
multi-layer orchestration support functional element in the MMO functional component for the purpose of
inter-domain orchestration between SDN MMF and OSS/BSS.
