Fcaps Model

Fcaps Model. The FCAPS model is a universal paradigm that is utilized for Element Management Systems (EMS) Network Management Systems (NMS) and Operation Support Systems (OSS) Users have distinct preferences and not all management and monitoring systems are created equal Users of monitoring and management systems require a reference model to determine.

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 Accounting BillingFault AssuranceConfiguration FulfillmentPerformance Assurance.

Fault ManagementConfiguration ManagementAccounting ManagementPerformance ManagementSecurity ManagementThe Tmn FrameworkFault management is a set of functions that enable the detection isolation and correction of abnormal operation of the telecommunication network The quality assurance measurements for fault management include component measurements for Reliability Availability and Survivability (RAS) Fault management consists of the following functions 1 RAS quality assuranceestablishes the reliability criteria that guide the design policy for redundant equipment (a responsibility of configuration management) and the policies of the other function groups in this area 2 Alarm surveillancedescribes the capability to monitor network element failures in nearreal time 3 Fault localizationdescribes where the initial failure information is insufficient for fault localization It has to be augmented with information obtained by additional failure localization routines at the application level 4 Fault correctiontransfers data concerning the repair of a fault and the control of procedures that Configuration management provides functions to identify collect configuration data from exercise control over and provide configuration data to network elements Configuration management supports the following functions 1 Installing the physical equipment and logical configurations 2 Service planning and negotiation which addresses planning for the introduction of new services changing deployed service features and disconnecting existing services 3 Provisioning which consists of necessary procedures to bring equipment into service but does not include installation As soon as the unit is ready for service the supporting programs are initialized via the TMN The state of the unit (in service out of service standby or reserved) and selected parameters may also be controlled by provisioning functions 4 Status and control where the TMN provides the capability to monitor and control certain aspects of the network element (NE) on demand Examples include checking or cha Accounting management lets you measure the use of network services and determine costs to the service provider and charges to the customer for such use It also supports the determination of charges for services Accounting management includes the following functions 1 Usage measurement— Consists of the following subfunctions 11 Planning and management of the usage measurement process 12 Network and service usage aggregation correlation and validation 13 Usage distribution 14 Usage surveillance 15 Usage testing and error correction 16 Measurement rules identification 17 Usage shortterm and longterm storage 18 Usage accumulation and validation 19 Administration of usage data collection 110 Usage generation 2 Tariffing and pricing—A tariff is used to determine the amount of payment for services usage 3 Collections and finance—Functionality for administering customer accounts informing customers of balances and payment dates and recei Performance management provides functions to evaluate and report on the behavior of telecommunication equipment and the effectiveness of the network or network element Its role is to gather and analyze statistical data for the purpose of monitoring and correcting the behavior and effectiveness of the network network elements or other equipment and to aid in planning provisioning maintenance and quality measurement Performance management includes the following functions 1 Performance quality assurance—Includes quality measurements such as performance goals and assessment functions 2 Performance monitoring— This component involves the continuous collection of data concerning the performance of the network element Acute fault conditions are detected by alarm surveillance methods Very low rate or intermittent error conditions in multiple equipment units may interact resulting in poor service quality and may not be detected by alarm surveillance Performance monitoring i Security is required for all functional areas Security management consists of two main functions 1 Security services for communications provide authentication access control data confidentiality data integrity and nonrepudiation These may be exercised in the course of any communications between systems and between users or customers and systems In addition a set of pervasive security mechanisms are defined that are applicable to any communication such as event detection security audittrail management and security recovery 2 Security event detection and reporting reports activities that may be construed as a security violation (unauthorized user physical tampering with equipment) on higher layers of security applications Security management includes the following functions 1 Prevention 2 Detection 3 Containment and recovery 4 Security administration The framework shown in Figure 33 brings it all together The different logical layers sit on top of each other each layer is responsible for implementing the FCAPS functionality and passes the collected information to the next layer From a customer&#39s applicability perspective after identifying and prioritizing the requirements you can map various network management products to this matrix and identify what is required to meet your needs From the perspective of this book relevant layers of the TMN architecture are the Network Element Layer (NEL) the Element Management Layer (EML) related to similar device types the Network Management Layer (NML) related to mediation and the Service Management Layer (SML) related to service monitoring and accounting The Business Management Layer (BML) is outside the scope of this book If you&#39re interested you&#39re encouraged to study the ITUT M series for more details Note that the FCAPS model describes the conceptual model of function.
