Hi Kim, I found an email that indicates OVS doesn't have built-in support. But it was a year ago, not sure whether it's supported now. http://openvswitch.org/pipermail/discuss/2011-July/005400.html
For sFlow, to me, it is similar to NetFlow, and usually used to track dynamic traffic in a network with the help of flow collector. There're lots of different collectors. What you can get through sFlow depends on what features the collector provides, not OVS. Not sure if there's a collector provides topology things. Maybe someone who is familiar with collector could give us some advice. Thanks.
