Thank you very much Mr. Petit for the prompt reply.
Do you know any hand-on example to implement that?

Subject: Re: [ovs-dev] asking the example to use openflow protocol to limit the
flow rate in openvswitch
The configuration of QoS is done through the OVSDB protocol, which handle
switch-level configuration. You can then use OpenFlow to direct flows to
particular queues that you've configured through OVSDB. There are C and Python
bindings to OVSDB (but I don't think NOX makes use of them) or you can use
ovs-vsctl as a CLI interface to OVSDB.
There's an example of configuring QoS towards the end of the ovs-vsctl man
page. The ovs-ofctl man page describes the enqueue and set_queue actions that
can be used to direct flows to the queues you've configured.
