RE: Why do you use Netflow

What are you looking at when you analyze this data?  I've 
seen uses 
such as top 10 destination AS's for peering evaluations.  
What else?  
Billing?

Also to get some application-specific bandwidth utilization numbers.

I wonder how do you map your netflow data to applications?
(if I understood correctly what you´re saying)

The caveat is that Netflow is useful for this purpose on a
smallish test/research network, in which port numbers and/or
combinations of port numbers and server addresses correllate to 
an application, which is what I happen to be doing.  Naturally 
on a public backbone you'd want to substitute "port-specific" 
for "application-specific".
