Sam,

OVER HERE!  LOOK HERE!  PICK ME!

:)  Seriously though, take a look at NetFlow.  Nice flow based accounting
exported at flow conclusion by the router to a 'collector'.  It records, on
a per-flow basis, src AS, src IP, src port, dst AS, dst IP, dst port, pkts
in flow, B in flow, start time, stop time, etc, etc, etc.  I'm sure you get
the idea; this is pretty powerful stuff!

You can have your collector aggregate all the flow exports over a given time
period, or you can have your router do it before it sends the info to the
collector.  Cisco sells their own commercial products to collect and analyze
and they also partner with 3rd party commercial vendors to provide you with
collectors and analyzers.  The best stuff though, IMHO, are the tools from
the open source community.  Cisco acknowledges these tools and even lists
where you can get them on their website, however, they are obviously not
supported.

Start here:

http://net.doit.wisc.edu/~plonka/FlowScan/

http://www.splintered.net/sw/flow-tools/

http://www.columbia.edu/acis/networks/advanced/CUFlow/


There are good examples of implementations here:

http://wwwstats.net.wisc.edu/

http://www.canet3.net/stats/map.html


And of course, although they have no relation to NetFlow, no disscussion of
network monitoring tools is complete without Tobi's Tools:

Sam,

Have you taken a look at NBAR? Take a look at the
Cisco IOS Quality of Service Solutions Configuration Guide
it should work for you.
