Abstract
Some embodiments provide a method for a first network controller located at a first domain that manages a logical network spanning several physical domains including the first domain. Upon reconnection to a second network controller located at a second physical domain of the several physical domains after a period of disconnect, the method receives a first set of updates indicating modifications to logical network state from the second network controller. The method reconciles any conflicts between (i) the logical network state stored at the first controller, (ii) the first set of updates received from the second network controller, and (iii) updates received from other network controllers located at different physical domains of the several physical domains. The method transmits a second set of updates to the second controller indicating modifications to the logical network state based on the reconciliation of conflicts.
