Re: limits - For Cisco/Juniper it's in the low hundreds of thousands of flows/sec per chipset/linecard for 1:1 NetFlow/IPFIX, I think. Then of course, as has been mentioned, you'll need to be able to send it and receive it to something - and store+query. Avi Freedman CEO, Kentik

Around here they are currently voting on a law that will require unsampled 1:1 netflow on all data in an ISP network with more than 100 users. Then store that data for 1 year, so the police and other parties can request a copy (with a warrant but you are never allowed to tell anyone that they came for the data and the judges will never say no).
My routers can apparently actually do 1:1 netflow and the documentation does not state any limits on that. So maybe I am lucky?
To the original question: in this country sFlow only is apparently about to become illegal.
