[ovs-discuss] connection to the controller

[dsainz at CS.technion.ac.il]

Hi all,

I'm trying to figure out how a switch is connected to the controller
inside of a network with several OVS. The switch has ports, and according
to the specification, also channels to connect to the controllers. My
question is whether each switch has a channel with a "direct" connection
to the controller or on the other hand that channel is but another OF
port.

What I'm trying to ask is, given a network created with several OVS and a
controller, when the controller sends a message to a switch, and to reach
that switch in the network you have to go through other switches, does
that message go routed through the OF switches of the network, passing
through flow tables etc like any other packet? Or that message has a
different kind of connection that doesn't go through the OF ports of the
switches?

Thanks in advance,

David.
