    Abstract: A network control system for generating physical control plane data for managing first and second managed forwarding elements that implement forwarding operations associated with a first logical datapath set is described. The system includes a first controller instance for converting logical control plane data for the first logical datapath set to universal physical control plane (UPCP) data. The system further includes a second controller instance for converting UPCP data to customized physical control plane (CPCP) data for the first managed forwarding element but not the second managed forwarding element. The system further includes a third controller instance for receiving UPCP data generated by the first controller instance, identifying the second controller instance as the controller instance responsible for generating the CPCP data for the first managed forward element, and supplying the received UPCP data to the second controller instance.

    Abstract: For a logical switching element implemented across several managed switching elements, some embodiments provide a method that receives a packet for processing through the logical switching element. The method performs a set of logical forwarding operations for determining a particular destination at the logical switching element to forward the packet. Based on the particular destination at the logical switching element, the method performs a set of physical forwarding operations for determining a destination at a managed switching element of the several managed switching elements that corresponds to the particular destination at the logical switching element. The method forwards the packet to the destination at the managed switching element.

    CPC classification number: H04L45/745

    Abstract: For a network that includes several managed edge switching elements and several managed non-edge switching elements that are for implementing a logical switching element, some embodiments provide a method of distributing packet processing across the several managed non-edge switching elements. The method receives a packet for processing through the logical switching element. Based on a determination that the packet needs to be processed by a managed non-edge switching element, the method determines a particular managed non-edge switching element of the several managed non-edge switching elements to forward the packet. The method forwards the packet to the particular managed non-edge switching element for the particular managed non-edge switching element to process the packet.
