As I mentioned, I would store it in the database and pull it using the OVSDB
protocol. Your controller would need to support OVSDB, which is defined here:
http://tools.ietf.org/html/draft-pfaff-ovsdb-proto
Alternatively, you could use one of the OVSDB utilities (e.g., ovs-vsctl or
ovsdb-client) to pull the data over a TCP/SSL socket onto the system running
your controller.
