[ovs-dev] Traffic Separation with OpenFlow

[Justin Pettit]

[Please keep this on the list.]

I don't think you need to use queues.  Just rules of the form:

	ovs-ofctl add-flow <br> priority=100,in_port=1,tcp,tp_dst=5001,output=3
	ovs-ofctl add-flow <br> priroity=50,in_port=1,output=2
	ovs-ofctl add-flow <br> priroity=50,in_port=2,output=1
	ovs-ofctl add-flow <br> priority=50,in_port=3,output=1

These weren't tested, but it should at least be enough to get you pointed in the right direction
