What is network management
Network management is the description of all functions and components for monitoring and controlling networks. These functionalities, which are geared towards the operation of the network, are part of the comprehensive IT management and e-management that controls business processes via the Internet.
Network management is the prerequisite for operating a network. Due to the complexity of larger networks, various control and route functions must be carried out by means of a network management system.The tasks of the network management therefore include the collection of information about the use of the network by the connected stations, the creation of reports and statistics for planning, operation, failure and maintenance, the configuration of the network and associated configuration changes, the performance, event and error monitoring. In connection with open communication, the international standardization organization (ISO) defined five functional areas for network management: error management, performance management, configuration management, bandwidth management, billing management and security management.
Error management combines all functions that can be used for error prevention, error detection and troubleshooting in the network.
The configuration management contains tools and functions for planning, expanding and changing the configuration as well as for maintaining the configuration information.
The performance management provides aids and tools for measuring and improving the performance of the network and for network tuning.
The billing management contains means for the proper handling of the use of the network, such as access management, consumer control and billing aids as well as information services.
Security management is responsible for monitoring access rights to networks, LAN segments, services and other resources.
