Chassis controllers for converting universal flows
First Claim
1. A network control system for generating physical control plane data for managing a set of managed forwarding elements that implements forwarding operations associated with a logical datapath set, the system comprising:
- a plurality of host computers, each of the plurality of host computers executing a managed forwarding element;
a first controller computer comprising (i) one or more processing units, (ii) a memory for storing a first controller instance executable by the one or more processing units of the first controller computer, and (iii) a network information base (NIB) storage, the first controller instance comprising sets of instructions for;
receiving input data defining the logical datapath set and performing a first conversion of data for the logical datapath set to generate intermediate data tuples for the logical datapath set;
storing the intermediate data tuples in the NIB storage; and
distributing the intermediate data tuples from the NIB storage to a set of the plurality of host computers that executes the set of managed forwarding elements; and
a second controller instance executing on a particular one of the plurality of host computers, the second controller instance comprising sets of instructions for;
receiving the intermediate data tuples for the logical datapath set from the NIB storage; and
converting the intermediate data tuples into physical control plane data for use by a managed forwarding element executing on the particular one of the plurality of host computers.

Abstract
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 is described. The system includes (1) a first controller for converting logical control plane data for the first logical datapath set to universal physical control plane (UPCP) data, (2) a second controller for converting UPCP data to customized physical control plane (CPCP) data for the first managed forwarding element but not the second managed forwarding element, and (3) a third controller for receiving UPCP data generated by the first controller instance, identifying the second controller as the controller instance responsible for generating the CPCP data for the first managed forward element, and supplying the received UPCP data to the second controller. Each controller includes a network information base (NIB) storage for exchanging data with another controller instance.

16. A non-transitory machine readable medium of a host machine storing a first controller application executable by at least one processor of the host machine, the first controller application for managing a managed forwarding element that executes on the host machine, the first controller application comprising sets of instructions for:
-
receiving, from a second controller application that executes on a separate controller computer having one or more processing units for executing the second controller application and a memory for storing the second controller application, a set of intermediate data tuples for a logical datapath set implemented by the managed forwarding element, wherein the intermediate data tuples are generated by a third controller application based on input data that defines the logical datapath set; converting the intermediate data tuples for the logical datapath set into physical control plane data for use by the managed forwarding element on the host machine; and distributing the physical control plane data to the managed forwarding element within the host machine, wherein the first controller application uses a network information base (NIB) storage for receiving the set of intermediate data tuples and distributing the physical control plane data. - View Dependent Claims (17, 18, 19, 20, 21, 22)
