Physical controllers for converting universal flows

摘要

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.

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.
