FCAPS is an acronym for Fault, Configuration, Administration/Accounting, Performance, and Security.
A network manager’s ability or rather responsibility is to maintain and administer a computer network. Network management is the execution of the set of functions required for planning, allocating, deploying, controlling, coordinating and monitoring the resources of a network.
TMN identifies five functional level of telecommunications management from top to bottom as – Business Management, Service Management, Network Management, Element Management and Network Element. In addition to representing the flow of information from a management layer to the layers above and below it, the ITU-T has also splitted the functionality offered by management systems into the five key areas of Fault, Configuration, Accounting, Performance and Security.
You can find a very good article on TMN Model here.
Now, let’s get into the details of each functional area:
Fault Management: Allows management systems to discover faults in managed devices, find out the root cause and take necessary corrective action. Fault management provides mechanisms to:
- Report the occurrence of faults
- Perform diagnostic tests
- Log Reports
- Acknowledge / Correct faults
Configuration Management: Allows to monitor network and provide the abilities to:
- Initialize the managed devices
- Configure the managed devices
- Re-configure the managed devices
- Operate on the managed devices
- Stop the managed devices
Accounting: Allows to measure network utilization of individual users or groups. For system where accounting is not applicable “A” stands for administration. Accounting management provides the abilities to:
- Provide billing information
- Help keep network performance at an acceptable level
Performance Management: Allows to measure various aspects of network performance including the gathering and analyzing statistical data such as PM, about the system so that it may be maintained at an acceptable level. Performance management provides the ability to:
- Obtain the utilization of network devices
- Obtain the error rates of network devices
- Provide a consistent level of performance by ensuring that devices have a sufficient capacity.
Security Management: Allows to control access to network resources so that information is secured and can not be obtained without authorization by:
- Limiting access to network resources
- Providing notification of security breaches and attempts
TMN model partitions the functional areas of management into layers. Thus, FCAPS have a different set of tasks at each layer.
