The network controller is located at a particular one of the several physical domains. The network controller includes a first storage for storing network state information that is local to the particular physical domain. The network controller includes a second storage for storing a first type of global network state information for the logical network. The network controller includes a third storage for storing a second type of global network state information for the logical network. The network controller includes an interface for communicating with other network controllers located at the other physical domains in the several physical domains spanned by the logical network. The interface is for sharing the first and second types of global network state information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Storing network state at a network controller","description":"Some embodiments provide a network controller for managing a logical network that spans several physical domains.
