thanks, seems a bit clearer.

Hi Samii,
Broadly speaking ‘in-band control’ means that the Control-Plane and Data-Plane
share the same transmission ‘channel’.
A typical example can be Rs-232 with XON/XOFF control bytes, which are sent
with data bytes over the same wire.
Or SMTP where the Control messages like ‘HELO’,etc are sent into the same
stream of Data messages (the mail body, for ex.).
The official docs describe this feature in ovs, just search “In-Band Control”
chapter at
http://openvswitch.org/support/dist-docs/DESIGN.md.html
With in-band control there's no separate/dedicated connection for ovs to
communicate with the Controller.
Hope that helps,
Antonio

Are you using in-band control? That's the situation.
