Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for maintaining, by a cloud controller, data representing a topology of a network of nodes; receiving, at the cloud controller from the first group of nodes, one or more requests to connect to the network; selecting, by the cloud controller, a first node in the first group of nodes that sent the request; and generating, by the cloud controller, instructions configured to cause the first node to communicate a timestamp of the first node to each neighboring node of the first node and to cause each neighboring node to communicate the timestamp of the first node to each other neighboring nodes of the neighboring node; and sending the instructions to the first node, thereby synchronizing the nodes in the network to the timestamp of the first node.

Abstract: A method includes receiving one or more node connections from a mesh network external to the data processing hardware. The mesh network includes a network of nodes each operative to transmit and/or receive directional beams containing packets of data. The method also includes identifying a route within the mesh network for providing a data packet from a source to a destination and determining schedule information associated with the identified route, the schedule information coordinating wireless communication between at least a first node and a second node along the route to transfer the data packet. The method also includes providing the schedule information to the first node and the second node.

Abstract: In a network including a plurality of network nodes interconnected via a plurality of primary links and a controller in communication with the plurality of network nodes, the controller is configured to provide an event profile to the plurality of network nodes, the event profile indicating routing changes to be implemented in a variety of link loss scenarios. Each of the plurality of nodes is configured to determine that a particular link loss event occurred, determine, based on the event profile, routing changes for the particular link loss event, and implement the determined routing changes.
