Abstract: Data center network architectures that can reduce the cost and complexity of data center networks. The data center network architectures can employ optical network topologies and optical nodes to efficiently allocate bandwidth within the data center networks, while reducing the physical interconnectivity requirements of the data center networks. The data center network architectures also allow computing resources within data center networks to be controlled and provisioned based at least in part on a combined network topology and application component topology, thereby enhancing overall application program performance.

The one or more collectors are configured to receive network traffic data from a plurality of network elements and extract metadata from the network traffic data. The network manager is configured to receive metadata from the one or more collectors. The network manager identifies a network control objective for the network, identifies a programmable parameter of the programmable network element to achieve the network control objective, and programs the programmable network element. The network manager further determines whether the network control objective is met after programming the programmable network element and applies a control loop based on the network control objective to program the programmable network element.

Abstract: Among other things, a method performed by a first access point is described. The method includes outputting signals. At least some of the signals interfere with communication between a device and a second access point. The method also includes determining whether to output the signals in a predefined mode based on dynamically calculated values of a parameter. The parameter is related to signal interference at the device. If it is determined to output the signals in the predefined mode, for a time period, the first access point outputs signals in the predefined mode.

Abstract: A communication network topology is determined by evaluating costs of states each representing a possible assignment of hubs and remote nodes to nodes of the communication network. The hubs connect to a central network, the remote nodes connect wirelessly to the hubs and obtain connectivity to the central network through the hubs. The cost of each state is determined based on costs for configuring each node as a hub or a remote node, uplink frequencies for sending data from the remote nodes to corresponding hubs, and downlink frequencies for sending data from the hubs to corresponding remote nodes.
