Abstract
Some embodiments provide a network control system for generating physical control plane data for managing first and second managed forwarding elements that implement forwarding operations associated with a first logical datapath set. The system includes a first controller instance for converting logical control plane data for the first logical datapath set to universal physical control plane (UPCP) data. The system includes a second controller instance for converting UPCP data to customized physical control plane (CPCP) data for the first managed forwarding element but not the second managed forwarding element. Each controller instance includes a network information base (NIB) storage for storing data and exchanging data with the other controller instance.
