摘要： Some embodiments provide a distributed control system for controlling managed switching elements of a network. The distributed control system comprises a first network virtualizer for converting a first set of input logical forwarding plane data to a first set of output physical control plane data. It also includes a second network virtualizer for converting a second set of input logical forwarding plane data to a second set of output physical control plane data. In some embodiments, the physical control plane data is translated into physical forwarding behaviors that direct the forwarding of data by the managed switching elements.

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.

摘要： For a network control system that receives, from a user, logical datapath sets that logically express desired forwarding behaviors that are to be implemented by a set of managed switching elements, a controller for managing several managed switching elements that forward data in a network that includes the managed switching elements is described. The controller includes a set of modules for detecting a change in one or more managed switching elements and for updating logical datapath set based on the detected change. The logical datapath set is for subsequent translation into a set of physical forwarding behaviors of the managed switching elements.
