For this to work though, you need a reliable data gathering method.
Netflow on high-speeds only do samples, if I remember with 5% deviation
of actual traffic. Question arises if that is accurate enough to use as
billing data....

In the IETF the ip-fix WG was supposed to create a protocol that would
solve this, they are now in the MPLS swap trying to figure out how to
generate statistics on MPLS sign of intelligent life.

If I remember correctly, Lasse Hanson (that I think is on the list)
told me that the problem with high-speed interfaces is not to generate
the data, it's to get it shipped off the router. So what we would need
is a protocol that would let you

a) from a few parameters choose what to generate stats for (source,
dest, packets, bytes, ports?)
b) Aggregate it on the router
c) Send in batch

Who writes the draft? :)
