No... It's action based. You can send it a different route, you can
replicate it, you can drop it, you can mutate it... You can send it to a
different destination for stateful filtering when it doesn't match an
expected pattern!

SDN is not just QoS routing, please stop saying that.

Anyway, prioritization needs more, not less,

to the top 50 doing traffic and default route the rest of the traffic. Less
