Concept
FCAPS
Summary
FCAPS is the ISO Telecommunications Management Network model and framework for network management. FCAPS is an acronym for fault, configuration, accounting, performance, security, the management categories into which the ISO model defines network management tasks. In non-billing organizations accounting is sometimes replaced with administration.
The ISO, under the direction of the OSI group, has created a network management model as the primary means for understanding the major functions of network management systems. The model in question is interchangeably called either the OSI network management model or ISO network management model so the full name could be the OSI/ISO network management model.
The comprehensive management of an organization's information technology (IT) infrastructure is a fundamental requirement. Employees and customers rely on IT services where availability and performance are mandated, and problems can be quickly identified and resolved. Mean time to repair (MTTR) must be as short as possible to avoid system downtimes where a loss of revenue or lives is possible.
In the early 1980s the term FCAPS was introduced within the first Working Drafts (N1719) of ISO 10040, the Open Systems Interconnection (OSI) Systems Management Overview (SMO) standard. At that time the intention was to define five separate protocol standards, one for each functional area. Since initial experiences showed that these protocols would become very similar, the ISO working group responsible for the development of these protocols (ISO/TC97/SC16/WG4, later renamed into ISO-IEC/JTC1/SC21/WG4) decided to create a single protocol for all five areas instead. This protocol is called common management information protocol (CMIP). In the 1990s the ITU-T, as part of their work on Telecommunications Management Network (TMN), further refined the FCAPS as part of the TMN recommendation on Management Functions (M.3400). The idea of FCAPS turned out to be very useful for teaching network management functions; most textbooks therefore start with a section that explains the FCAPS.
