Absolutely. That could be sufficient, in simple cases. Just set up a
flow that matches the traffic you want and enqueue it to where it should
However there are at least two problems:
- OpenFlow 1.0 doesn't allow enqueuing to the NORMAL port (or
even to the FLOOD port), so you have to know the correct
output port. (Open vSwitch could allow enqueuing to other
ports as an extension, but currently it doesn't.)
- ovs-ofctl does not support the "enqueue" action that is
required to take advantage of QoS. That's just an oversight.
I'll add fixing it to my to-do list.
