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