Abstract: Some embodiments provide a method for a global manager that manages a logical network spanning multiple physical sites. The method receives a set of data describing a modification to a definition of the logical network. From multiple queues that each correspond to a different one of the physical sites spanned by the logical network, the method identifying a set of queues to which to store the received set of data. The method stores the received set of data in the identified set of queues. From each respective queue in the identified set of queues, the method sends the set of data through a respective channel between the global manager and a respective local manager at the respective physical site corresponding to the respective queue.

Abstract: Some embodiments provide a method for a global manager that manages a logical network configuration for multiple datacenters that each have a local manager for managing the logical network configuration within the datacenter. Based on detecting that a connection to a particular local manager of a particular datacenter has been restored after a period of unavailability, the method identifies a portion of the logical network configuration that is relevant to the particular datacenter. In a series of transactions, the method transfers the identified portion of the logical network configuration to the particular local manager. During the series of transactions, the method identifies modifications to the identified portion of the logical network configuration to be included in the series of transactions. Upon completion of the series of transactions, the method transfers a notification to the particular local manager indicating completion of the series of transactions.
