Network Management is a part of Operations Support Systems, or O S S, that is used to monitor, measure and optimize the performance of a telecom network. It involves activities like:
ITU-T defined Telecom Management Network model (TMN) as a protocol for management of open-systems in any telecom network. TMN is a support network that interfaces the telecom networks, to provide means for transporting and processing operations, administration, maintenance, provisioning and management information. It basically provides a framework, for achieving interconnectivity and communication across heterogeneous operation systems, and telecommunications networks.
The course includes details on F CAPS which plays a key role in any telecommunication network. These management functions help in management of network, for deriving optimum performance. Shortly,
F → Fault Management
C → Configuration Management
A → Accounting Management
P → Performance Management
S → Security Management
The course includes Southbound and Northbound interfaces.
The Southbound Interfaces, or SB eyes are those that help the Network Management Systems connect to the Network Elements, and manage them. Its main objective is to provide communication, and management between the network's SDN controller, and physical or virtual switches and routers.
The Northbound Interfaces, or NB eyes are those that help the Network Management Systems, connect to OSS systems. They are used to enable Alarm, Performance, Inventory, Provisioning, Configuration, and Security related information of the Network Elements, and forwards it to the high-level management systems, typically referred to as the OSS systems.
Some of the concepts covered in the learning are TACACS, LDAP, SNMP, CORBA, XML, MTOSI, SOAP and important APIs in telecom.
