Abstract: In one embodiment, a router operating in a hierarchically routed computer network may receive collected data from one or more hierarchically lower devices in the network (e.g., hierarchically lower sensors or routers). The collected data may then be converted to aggregated metadata according to a dynamic schema, and the aggregated metadata is stored at the router. The aggregated metadata may also be transmitted to one or more hierarchically higher routers in the network. Queries may then be served by the router based on the aggregated metadata, accordingly.

Abstract: A system includes an on-board unit (OBU) in communication with an internal subsystem in a vehicle on at least one Ethernet network and a node on a wireless network. A method in one embodiment includes receiving a message on the Ethernet network in the vehicle, encapsulating the message to facilitate translation to Ethernet protocol if the message is not in Ethernet protocol, and transmitting the message in Ethernet protocol to its destination. Certain embodiments include optimizing data transmission over the wireless network using redundancy caches, dictionaries, object contexts databases, speech templates and protocol header templates, and cross layer optimization of data flow from a receiver to a sender over a TCP connection. Certain embodiments also include dynamically identifying and selecting an operating frequency with least interference for data transmission over the wireless network.

Abstract: A method for communicating optically between nodes of an optical network, including forming, between a first node and a second node of the network, a set of lightpaths, each of the set of lightpaths having a respective configuration, and transferring communication traffic between the first and second nodes via the set of lightpaths. The method also includes forming a determination for the set of lightpaths that a communication traffic level associated therewith is less than a predetermined threshold, and in response to the determination, removing a lightpath having a given configuration from the set of lightpaths to form a reduced set of lightpaths. The method further includes transferring the communication traffic between the first and second nodes via the reduced set of lightpaths, while reducing a level of power consumption in the removed lightpath and while maintaining the given configuration of the removed lightpath.
