FCAPS

FCAPS is the ISO model for network management. It forms the cornerstone of current day network management.

It is an acronym for Faults, Configuration, Accounting, Performance, Security, the categories into which the model breaks the various network management tasks.

Overview

Fault Management

The goal of fault management is to recognize, isolate, correct and log faults that occur in the network.

When a fault or event occurs, a network component will often send a notification to the network operator using a proprietary or open protocol such as SNMP.

Configuration Management

The goals of configuration management include:

  • to gather and store configurations from network devices
  • to simplify the configuration of the device
  • to track changes which are made to the configuration
  • to configure ('provision') circuits or paths through non-switched networks

Accounting (Administration)

Accounting is often referred to as billing management. The goal is to gather usage statistics for users.

Using the statistics the users can be billed and usage quota can be enforced.

Examples:

  • Disk usage
  • Link utilisation
  • CPU time

RADIUS, TACACS and DIAMETER are examples of protocols commonly used for accounting.

For non-billed networks, 'Administration' replaces 'Accounting'. The goals of Administration is to administer the set of authorized users, by establishing users, passwords and permissions; and to administer the operations of the equipment such as by performing software backup and synchronization.

Performance Management

Performance management enables the manager to prepare the network for the future.

By collecting and analysing performance data, the network health can be monitored. Trends can indicate capacity or reliability issues before they become service affecting.

Performance thresholds can be set in order to trigger an alarm. The alarm would be handled by the normal fault management process (see above).

Security Management

The first task of security management is the identification of risks. Next these risks need to be secured and managed.

Other models

Other models for network management are available. One example is the ITIL model.
