I see no mention of UDP in this article, which is what 99% (if not more) voice and video traffic is transmitted as (omitting stuff wrapped in HTTP). Can it also detect flows of UDP?
TCP and UDP packets look pretty much the same as far as this design is concerned. It's all IPv4 where the IP header has IP source/dest address and a TCP/UDP bit. The source/dest _ports_ are in the first 32 bits of the TCP or UDP portion of the message. So it should be trivial to include UDP, but that probably wasn't mentioned because it would be "too technical" for this level of ad.
