[ovs-discuss] how does tos/dscp mechanism work on ovs?

[Justin Pettit]

OVS doesn't automatically do anything with those fields itself.  If you want to do that, you can configure queues and then write flows that match on those fields and output to a particular queue.

I mean the packets are outputted according to the priority of their TOS/DSCP bits when there is congestion at the specified out port.
