Abstract:
1. A network control system for generating physical control plane data for managing a set of managed forwarding elements that implement forwarding operations associated with a first logical datapath set, the system comprising: a first controller computer comprising a first network information base (NIB) storage, the first controller computer for (i) receiving logical control plane data that define the logical datapath set, (ii) converting the logical control plane data to universal physical control plane (UPCP) data that define a first set of forwarding behaviors that is common between every managed forwarding element in the set of managed forwarding elements, and (iii) storing the UPCP data in the first NIB storage; and a second controller computer comprising a second NIB storage, the second controller computer for (i) receiving the UPCP data from the first NIB storage, (ii) converting the UPCP data to customized physical control plane (CPCP) data that define a second set of forwarding behaviors for a particular managed forwarding element in the set of managed forwarding elements, and (iii) storing the CPCP data in the second NIB storage.
