Abstract
Some embodiments provide a novel network control system that provides publications for managing different slices (e.g., logical and/or physical entities) of a network. The publications are published from publisher controllers in the network control system to subscriber controllers. The network control system uses publications with generation numbers and buffered subscribers to implement the fixed points in order to help maintain a consistent network state. The information published with a publication is useful for resolving conflicts in the network control system when multiple publisher controllers provide conflicting inputs to a subscriber controller.
