Cisco ISG Accounting Accuracy for LNS Sessions
The ISG Accounting Accuracy for LNS Sessions feature improves the accuracy of reported statistics for the
LNS sessions and traffic classes in the Stop Accounting messages. Because of the distributed nature of the
Cisco ASR 1000 Series Aggregation Services Routers, subscriber statistics are collected periodically every
10 seconds to balance the impact to statistics accuracy, and call setup and teardown rates. Statistics reports
that are generated using this collection are therefore up to 10 seconds old. When the Accounting Accuracy
feature is enabled, the most recent statistics are retrieved for particular subscribers in specific conditions,
such as when a session is torn down or stopped.
