摘要:
Some embodiments provide a virtualizer for managing a plurality of managed switching elements that forward data through a network. The virtualizer comprises a first set of tables for storing input logical forwarding plane data and a second set of tables for storing output physical control plane data. It also includes a table mapping engine for mapping the input logical forwarding plane data in the first set of tables to output physical control plane data in the second set of tables by performing a set of database join operations on the input logical forwarding plane data in the first set of tables. In some embodiments, the physical control plane data is subsequently translated into physical forwarding behaviors that direct the forwarding of data by the managed switching elements.

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.

Some embodiments provide a method for managing several managed switching elements in a network. The method determines configurations for the several managed switching elements to implement a first logical data path set. Based on the determined configurations, the method configures a first set of the several managed switching elements to implement the first logical data path set. The method configures a second set of the several managed switching elements to implement a second logical data path set.
