Hi Geetha, For OpenVSwitch, you can configure quality of service with ovs-vsctl. Check the manpage [1] under the "configuration cookbook" section -- there is an example titled "Quality of Service (QoS)".
For tc queueing configuration, there is a neat example and tutorial on using hierarchical token buckets in http://luxik.cdi.cz/~devik/qos/htb/manual/userg.htm [1] http://openvswitch.org/cgi-bin/ovsman.cgi?page=utilities%2Fovs-vsctl.8 Good luck!
