Abstract:
1. A distributed network control system for controlling a plurality of managed switching elements that forward data in a network, the distributed network control system comprising: a first controller executing a first control application, the first control application for receiving a first set of input logical control plane data that specifies a first set of logical data path (LDP) sets and converting the first set of input logical control plane data into a first set of output logical forwarding plane data that defines the first set of LDP sets in terms of a first set of logical forwarding rules, the first set of output logical forwarding plane data for translation into a first set of physical forwarding rules that directs the forwarding for a first set of managed switching elements of the plurality of managed switching elements; and a second controller executing a second control application, the second control application for receiving a second set of input logical control plane data that specifies a second set of LDP sets and converting the second set of input logical control plane data into a second set of output logical forwarding plane data that defines the second set of LDP sets in terms of a second set of logical forwarding rules, the second set of output logical forwarding plane data for translation into a second set of physical forwarding rules that directs the forwarding for a second set of managed switching elements of the plurality of managed switching elements.
