If a network administrator wants to tabs between any two Autonomous Systems, it would usually be a time-consuming work to get the values from each router. The accuracy is also not very guaranteed.
NetFlow Analyzer uses the BGP information exported from the router, to show the AS name, AS number, and the IN/OUT traffic.
To enable the AS View in NetFlow Analyzer:
Navigate to Settings>NetFlow>Storage Settings>AS View
The AS view tab shows the current autonomous systems details such as, AS name, AS number, IN traffic, and OUT traffic.
Once an autonomous system is clicked on, you can see additional details like source, destination, application, port, protocol, and traffic consumed.
