I don't know of an in-depth discussion. I'll point out, though, that
the architecture of the controller makes a great difference. If the
controller is reactive, that is, if it sets up flows in reaction to
traffic (received via packet-ins), then it will be affected much more by
the RTT to the switch than if it is proactive.

You can use Google or another search engine to search, if you specify
"site:openvswitch.org". Works quite well.
