Claim Text:
1. A non-transitory machine readable medium storing a program, which when executed by at least one processing unit provides a first network controller instance that is part of a network control system comprising a plurality of network controller instances, the program comprising sets of instructions for: generating, based on logical forwarding plane data that specifies a particular logical data path set in terms of logical forwarding behaviors of the particular logical data path set, output physical control plane data that specifies rules for at least a first managed switching element and a second managed switching element, respectively, to follow in order to implement the particular logical data path set, wherein the first network controller instance is a master controller instance for the particular logical data path set and the first managed switching element; and sending (i) the output physical control plane data that specifies rules for the first managed switching element to the first managed switching element and (ii) the output physical control plane data that specifies rules for the second managed switching element to a second network controller instance that manages the second managed switching element.
