Thanks for pointing that out David. 

One more question: When we add-port using vsctl, that gets added to the bridge and lets us map to a physical port right. So, where does vport come in here ? I mean, how does it map with the physical port? I see from the code that vports are used to receive packets coming to the switch (ovs_vport_receive) and to send (ovs_vport_send).

Thanks,
Monica

Hi Monica,

The messaging mechanism that OVS is using is provided by the operating system, OVS doesn't implement it, it just uses and invokes it.

cheers,

David.
