Feel free to contact peering () netflix<dot>com - we're happy to provide
you with delivery statistics for traffic terminating on your network.

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
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
