    摘要： For a managed network including first and second managed switching elements that implement logical data path sets, some embodiments provide a method that establishes, from the first managed switching element, a network tunnel through a network to the second managed switching element. The network includes a set of unmanaged switching elements. Through the network tunnel, the network forwards logical network data to the set of unmanaged switching elements for the set of unmanaged switching elements to forward to the second managed switching element. The logical network is hidden from the set of unmanaged switching elements when the logical network data is forwarded through the tunnel.

    摘要： 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.
