LOGICAL ROUTER PROCESSING BY NETWORK CONTROLLER

摘要

Some embodiments provide a network controller for managing a logical network implemented across several managed network elements. The logical network includes at least one logical router. The network controller includes an input interface for receiving configuration state for the logical router. The network controller includes a table mapping engine for generating data tuples for distribution to the managed network elements in order for the managed network elements to implement the logical router. The network controller includes a route processing engine for receiving a set of input routes from the table mapping engine based on the configuration state for the logical router, performing a recursive route traversal process to generate a set of output routes, and returning the set of output routes to the table mapping engine. The table mapping engine uses the set of output routes to generate the data tuples for distribution to the plurality of managed network elements.

1. A network controller for managing a logical network that is implemented across a plurality of managed network elements, the logical network comprising at least one logical router, the network controller comprising:
an input interface for receiving configuration state for the logical router; a table mapping engine for generating data tuples for distribution to the plurality of managed network elements in order for the managed network elements to implement the logical router; and a route processing engine for (i) receiving a set of input routes from the table mapping engine based on the configuration state for the logical router, (ii) performing a recursive route traversal process to generate a set of output routes, and (iii) returning the set of output routes to the table mapping engine, wherein the table mapping engine uses the set of output routes to generate the data tuples for distribution to the plurality of managed network elements.
