Editing FCAPS (section)

==The five areas of function of the model==
The OSI network management model categorizes five areas of function, sometimes referred to as the "FCAPS model:"  FCAPS can be seen as the predecessor of the newer FAB model defined in the [[Business Process Framework (eTOM)]]. FAB is short for fulfillment, assurance, billing. As guideline, you can map the two models as follows:

{| class="wikitable" style="margin:1em auto;"
|+ FCAPS and ISO (FAB) models
|-
! FCAPS !! FAB
|-
| Fault || Assurance
|-
| Configuration || Fulfillment
|-
| Accounting || Billing
|-
| Performance || Assurance
|-
| Security || Fulfillment
|}

The FCAPS model can be seen as bottom-up or network-centric. The FAB model looks at the processes more from top-down, is customer/business-centric.  The two standards that have emerged are [[Simple Network Management Protocol]] (SNMP) by [[IETF]] and [[Common Management Information Protocol]] (CMIP) by [[ITU-T]].
