Method and apparatus for using a network information base to control a plurality of shared network infrastructure switching elements

摘要

Some embodiments provide a program for managing several switching elements. The program receives, at a network information base (NIB) data structure that stores data for managing the several switching elements, a request to modify data stored in at least one particular switching element. The program modifies at least a first set of data tuples stored in the NIB for managing the particular switching element. The program sends a request to the particular switching element to modify at least a second set of data tuples for managing the particular switching element's operation.
