Try looking for "netflow". It's a traffic accounting protocol invented
by Cisco and supported by most Cisco routers and Linux via ntop or
nprobe. Mostly used by ISPs.
Accounts ip-proto,address,port,as-number,tcpflags,num_packets,num_bytes.
It is normally installed on the border routers of the ISP facing the
customer and the upstream providers interfaces (i.e. backbone traffic
is not accounted) but you can alter this setup.
