If it is a distributed controller environment, i would like to know, how controllers discover each other ? Does this handles by openflow it self ? Highly appreciate your thoughts..

Some controllers support active/standby model but as i understand there is no distributed controller support in openflow controllers. There may be SDN controllers which supports distributed controllers to create virtual networks.
