Understanding the need for Accounting Management
What is accounting management?
Why do networks require accounting management?
Why is accounting almost a stealth area within network management?
Which problems do accounting management solutions solve?
How can the business use this information for network planning, redesign, and billing?
What aspects make up accounting (data collection, data analysis, reporting, billing, and so on)?
Defining accounting
management
ITU-T definition (M.3400 and X.700, Definitions of the OSI Network Management Responsibilities):
"Accounting management • enables charges to be established for the use of
resources in the OSIE [Open Systems Interconnect Environment], and for
• costs to be identified for the use of those resources”
ITU-T definition (M.3400 and X.700, Definitions of the OSI Network Management Responsibilities):
• "inform users of costs incurred or resources consumed”inform
• "enable accounting limits to be set and tariff schedules to be associated with the use of resources;
limit
• "enable costs to be combined where multiple resources are invoked to achieve a given communication objective."

The Fulfillment, Assurance, and
Billing (FAB) model of TMF's eTOM
Telecommunication Management Forum (TMF) definition: The TMF refers to the ITU-T accounting definition
(M.3400) and provides additional details for billing in the enhanced Telecom Operations Map (eTOM), The Business Process Framework, Document GB921.
The Fulfillment, Assurance, and Billing (FAB) model of TMF's eTOM positions the "Network Data Management" building block between assurance and billing. "Network Data Management:
this process encompasses the collection of usage data and network and information technology events and data for the purpose of network performance and traffic analysis. This data may also be an input to Billing (Rating and Discounting) processes at the Service Management Layer, depending on the service and its architecture." Chapter 3 explains the FAB model in more detail.
IETF definition: Request For Comment (RFC) 2975, Introduction to Accounting Management
the collection of resource
consumption data for the purposes of capacity and
trend analysis, cost allocation, auditing, and
billing.
Accounting management requires that
resource consumption be
measured, rated, assigned, and communicated
between appropriate
parties."
In this book, we use the term accounting management to describe the following processes:
Collecting usage data records at network devices
Optionally preprocessing data produced by the device (for example, filter, sample, aggregate)
Exporting the data from the device toward a collection server
Processing the data at the collection server (for example, filter, sample, aggregate, de-duplicate)
Converting usage records into a common format to be used by higher-layer applications : the mediation procedure
