The 7705 SAR accounting logs collect comprehensive statistics to support several billing models. The 7705 SAR collects accounting data on services and on network interfaces on a per-forwarding class basis.
In addition to gathering information critical for service billing, accounting records can be analyzed to provide insight about customer service trends for potential service revenue opportunities. Accounting statistics on network ports can be used to track link utilization and network capacity planning. This information is valuable for traffic engineering and capacity planning within the network core.
The 7705 SAR also supports SAA accounting policies.
Accounting statistics are collected according to the parameters defined within the context of an accounting policy. Accounting policies are applied to customer Service Access Points (SAPs) and network interfaces. Accounting statistics are collected by counters for individual service queues defined on the customer’s SAPs or by the counters within forwarding class (FC) queues defined on the network ports.
The type of record defined within the accounting policy determines where a policy is applied, which statistics are collected, and the time interval at which to collect statistics.
The only supported destination for an accounting log is a compact flash system device (cf3: on all platforms; also cf1: or cf2: on the 7705 SAR-18). Accounting data is stored within a standard directory structure on the device in compressed XML format.
