[ovs-discuss] ovs-ofctl queue-get-config issue

[fatt 3issam]

Thank you.If I understood, No version of OpenFlow can tell me max and min rates of a queue on an OVS and I totally can't force a link-rate  nor a port speed by any means in OVS because they are virtual interfaces. What should I do then to limit the bandwidth in a simulated network of Open VSwitches?!
