    摘要: For a logical switching element implemented across several managed switching elements, some embodiments provide a method that receives a packet for processing through a logical processing pipeline of the logical switching element. The method processes the packet through a first set of stages of the logical processing pipeline of the logical switching element. The method generates a set of context tag values for indicating that the packet has been processed through the first set of stages of the logical processing pipeline. The method forwards the packet to a managed switching elements of the several managed switching elements for the managed switching element to further process the packet based on the context tag of the packet.

    摘要: Some embodiments provide a network virtualization apparatus for managing a plurality of managed switching elements that forward data in a network. The network virtualization apparatus comprises a controller for converting logical control plane data to logical forwarding plane data. It also includes a virtualizer for converting the logical forwarding plane data to physical control plane data. In some embodiments, the physical control plane data is subsequently translated into physical forwarding plane data that direct the forwarding of data by the managed switching elements.

    摘要: Some embodiments provide a novel method for forwarding a packet at a first managed interconnection switching element in a managed network of interconnection switching elements. The method receives a packet from a source machine on a first network segment in a first network. The packet identifies a destination machine located on a second network segment in a second, different network. The method removes a context tag that identifies the first network segment. The method uses the identification of the first network segment to determine a logical switching element that connects at least the first and second network segments. The method encapsulates the packet with a logical context identifier that identifies a logical port of the logical switching element. The logical port corresponds to the second network segment. The method transmits the twice-encapsulated packet towards a second managed interconnection switching element at the second network.

    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.
