I am a puzzled by the orthodoxy that seems to prevail around the value "flows" as a measure of network traffic in packet switched networks.
What platforms actually do real unsampled netflow today, and do it well for multi-10gigabit worth of typical Internet traffic?
Most of the platforms I know of do sampled netflow at 1:100-1:1000 or so, and then I don't really see the fundamental difference in doing the flow analysis on the router itself (classic netflow) or doing the same but at the sFlow collector.
