Yeah, that's an interesting one. We currently utilize netflow for this, but you also need to consider that
netflix streaming is just port 80 www traffic. Because netflix uses CDNs, its difficult to pin down the
traffic to specific hosts in the CDN and say that this traffic was netflix, while this traffic was the
latest windows update (remember this is often a shared hosting platform). We've done our own testing and
have come to a good solution which uses a combination of nbar, packet marking, and netflow to come to a
conclusion. On a ~160Mbps link, netflix peaks out between 30-50Mbps around 8-10PM each evening. The rest
of the traffic is predominantly other forms of HTTP traffic (including other video streaming services).

Also checkout Adrian Cockcroft presentations on their architecture which
describes how they use aws and CDns etc
