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.
A method for a device controller configuring a managed hardware forwarding element (HFE) in a network comprising (i) a plurality of managed software forwarding elements (SFEs) implementing a logical forwarding element along with the managed HFE and (ii) a set of central controllers, the method comprising:
A non-transitory machine readable medium storing a program for a device controller which, when executed by at least one processing unit of a computing device, configures a managed hardware forwarding element (HFE) in a network comprising (i) a plurality of managed software forwarding elements (SFEs) implementing a logical forwarding element along with the managed HFE and (ii) a set of central controllers, the program comprising sets of instructions for:
