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).Martin Hepworth wrote the following on 12/3/2011 2:36 AM:Also checkout Adrian Cockcroft presentations on their architecture whichdescribes how they use aws and CDns etc Martin
