Looking for a reliable bandwidth utilization NetFlow billing or NetFlow accounting system? If you are already using Cisco NetFlow technology for network monitoring and management, then it’s just one more simple step to extending that to bandwidth billing.
Using the Advanced Reporting Module for Scrutinizer NetFlow & sFlow Analyzer and a customized Billing configuration, you can monitor the bandwidth usage of your customers and also provide a data export to your current billing application.
The Advanced Reporting Module allows you to restrict your customers to view specific devices and/or interfaces in Scrutinizer. The “Scrutinizer v7 NetFlow and sFlow Analyzer: Using the Service Provider Module” blog has more information on this module’s features.
The Billing configuration is generally a customized solution using the enhanced features of the Advanced Reporting Module and importing that data into your billing application.
A custom data file (i.e. saved report filter) is created and exported every hour, giving the most granular data (1 minute intervals) available. The data file can include but is not limited to:
- Time Stamp
- Rate: bytes / second
- Peak: same as above when reporting at 1 minute intervals
- Totals: total bytes per minute
Any NetFlow or sFlow exported field can be included (bits, packets, percent, IP/MAC addresses, VLAN ID, applications, ToS, Autonomous System, etc.) if required. The billing application or script can then read in the files exported by Scrutinizer at a definable interval.
You should also know that Flexible NetFlow using a Permanent Cache can also be used for importing data into your billing application.
If your billing application is based on 95th percentile measurements, this information is also available in the Traffic Volume report displayed below.
95th percentile billing allows for the top 5% of spikes in a given period to be dropped from the utilization reported. In the example above, 95th percentile for Inbound is 99.78% and Outbound is 24.81%. This report is based on a one hour timeframe, providing both Inbound and Outbound traffic for the T1 interface.
