Since we have implemented the prototype on OVS, it had to be layered on OVSDB. 
Otherwise, OVS does not have any other way to be configured other than OVSDB 
interface when applicable - we would also have to use vsctl commands for some 
configuration data. 

Other OpenFlow-capable virtual switch implementations (such as LINC - no OVSDB 
or any DB) may have native support for OFConfig to work.

It's interesting.  I have always contended that layering OF-CONFIG over OVSDB 
would be a reasonable approach.  I guess this prototype demonstrates that it is 
possible.
