Is it Possible to create two instance of Controller in OFTest

[AshaSinghP]

Hi,

I am using OFtest for testing Openflow 1.3 switches.
I use Cpqd softswitch (of13softswitch) for this Purpose.

In Openflow 1.3 there is Multiple Controllers,

(for ex:) In Openflow 1.3 Specification It tells
"Asynchronous messages may need to be send to multiple controllers, the message is duplicated for each eligible OpenFlow channel and each message sent when the respective controller connection allows it."

Suppose I want to test the above statements, How should i use/create Multiple Controllers in OFTest.

Can Someone Help me out with this ..

Thanks
Asha
