Network management

Under Network management refers to the management, operation and maintenance and monitoring of IT networks and telecommunications networks. The English term for these activities is OAM Operation, Administration and Maintenance.

The ISO has the FCAPS model developed to describe the functional tasks of network management:

  • (F) Fault Management / error management: Identifying, logging, reporting and fixing error states
  • (C ) Configuration Management / Configuration Management: detection of all components ( configuration items ) that need to be monitored
  • (A) Accounting Management / Payroll Management: detecting the use of the network, so that invoices can be made
  • (P ) Performance Management Performance Management /: Collect market values ​​/ performance data and maintain statistics specify limits
  • (S ) Security Management / Security Management: user authentication, authorization of access and use

Many of these tasks is supported by computer-based network management systems. However, real network management systems typically support only some of these tasks.

IP networks are often managed and monitored by means of Simple Network Management Protocol (SNMP) and / or Windows Management Instrumentation (WMI). In larger networks, other protocols such as SAA or Netflow can be used. In the national and international telecommunication networks, proprietary protocols with higher performance are used in Germany for example, QD2, in the U.S. Transaction Language 1 (TL1 ). Because of the much higher in comparison with a private network number of network elements, protocols can not be used based on the polling. In Europe, OSI protocols are used.

The Telecommunications Management Network ( TMN ) is the set of ITU- T standards for the management of large telecommunication networks.

Under network monitoring refers to the monitoring and regular monitoring of networks whose hardware (such as servers, routers, switches ) and services ( such as Web servers, DNS services, email services). A distinction is made between external and internal monitoring. For external monitoring, an additional monitoring device is connected to the network, not the internal monitoring. Further characterization is made active and passive with the terms. In active monitoring, additional packets are sent into the network, the passive is only " overheard ".

The TeleManagement Forum has as part of the New Generation Operations Systems and Software program ( NGOSS ) is a model among other things, developed for the above-mentioned fields of activity, which has been found in the service provider sector -wide distribution.
