For a virtual distributed network environment employing physical forwarding elements that includes both software forwarding elements and third party devices serving as hardware forwarding elements, a scalable method for synchronizing configuration data of logical forwarding elements that are distributed across the various physical forwarding elements is provided. The method generates and updates the configuration data at a set of central controllers and then distributes the configuration data to the physical forwarding elements. The method delivers the updated configuration data to some of the physical forwarding elements by (i) determining a delta/differential between the updated configuration data held at the central controller and the obsolete configuration data held at those physical forwarding elements and (ii) delivering the determined differential configuration data to the physical forwarding elements.
