摘要: 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 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 further 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.

摘要: In a hierarchical switching architecture that includes at least one lower level managed switching element that connects to several higher level managed switching elements, some embodiments provide a method of identifying a higher level managed switching element to which the lower level managed switching element forwards a packet for further processing. The method computes a distribution metric based on a set of attributes of the packet. The method performs a lookup on a hierarchy traversal table that specifies (1) a set of primary higher level managed switching elements and (2) a set of secondary higher level managed switching element. The lookup is for determining a higher level managed switching element specified in the hierarchical traversal table to forward the packet for further processing. The method forwards the packet to the determined higher level managed switching element.
