Network management is the process of administering and managing computer networks. Services provided by this discipline include fault analysis, performance management, provisioning of networks and maintaining quality of service. Network management software is used by network administrators to help perform these functions.
Viewing: Network data can be viewed in a graphical web-based frontend. Acknowledging: Users can interact with the software through the web-based frontend to acknowledge alarms or manipulate other notifications. Reporting: Specific reports on network data can be configured by the user and executed through the web-based frontend.
Within the field of network management, event correlation is performed in a management platform typically known as a Network Management Station or Network Management System (NMS). For example, events may notify that a device has just rebooted or that a network link is currently down.
A big issue of network and service management is the ability to manage and control the network elements of the access and core networks. Historically, many efforts have been spent in standardization fora (ITU-T, 3GPP) in order to define standard protocol for network management, but with no success and practical results.
Traditionally, the logical network inventory has been a separate product but in most modern systems the functionality is built in the GIS serving both the functionality of the physical network and logical network. Water network information system typically manages the water network components, such as ducts, branches, valves, hydrants ...
Monitoring: This function enables the network management software to monitor the network for problems and to suggest improvements. [2] [3] The software may poll the devices periodically or register itself to receive alerts from network devices. One mechanism for network devices to volunteer information about itself is by sending an SNMP Trap ...
In electricity distribution circuits, Active Network Management (ANM) describes control systems that manage generation and load for specific purposes. This is usually done to keep system parameters (voltage, power, phase balance, reactive power and frequency) within predetermined limits. ANM generally refers to automated systems.
A network operating system (NOS) is a specialized operating system for a network device such as a router, switch or firewall.. Historically operating systems with networking capabilities were described as network operating systems, because they allowed personal computers (PCs) to participate in computer networks and shared file and printer access within a local area network (LAN).
