    摘要: 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.

    摘要: A method is provided in one example and can include receiving a source data stream, generating a base layer sub-stream from the source data stream, and generating an enhancement layer sub-stream from the source data stream. The method further includes communicating the base layer sub-stream to a client device using a first communication protocol, and communicating the enhancement layer sub-stream to the client device using a second communication protocol. In a particular example, the one-to-many communication protocol is a multicast communication protocol and the second communication protocol is a unicast communication protocol. In another example, the base layer sub-stream is sent to the client device via a first network connection and the enhancement layer sub-stream is sent to the client device via a second network connection.

    摘要: A statistical transition map is built based on mobile wireless device user mobility history data. This data is useful to assist various wireless local area network applications. Received signal strength and location trace information associated with movements of mobile wireless devices in a wireless network is collected. The received signal strength and location trace information is converted to a sequence of natural language pseudo-location word labels representing pseudo-locations of each mobile wireless device as each mobile wireless device moves about with respect to a plurality of wireless access point devices in the wireless network. A statistical transition map is generated for each mobile wireless device from the sequence of natural language pseudo-location word labels using a natural language model. A probability of a next pseudo-location for a particular mobile wireless device is computed based on its current location and its statistical transition map.

    摘要: The present invention provides improved methods and devices for managing network congestion. Preferred implementations of the invention allow congestion to be pushed from congestion points in the core of a network to reaction points, which may be edge devices, host devices or components thereof. Preferably, rate limiters shape individual flows of the reaction points that are causing congestion. Parameters of these rate limiters are preferably tuned based on feedback from congestion points, e.g., in the form of backward congestion notification (“BCN”) messages. In some implementations, such BCN messages include congestion change information and at least one instantaneous measure of congestion. The instantaneous measure(s) of congestion may be relative to a threshold of a particular queue and/or relative to a threshold of a buffer that includes a plurality of queues.

    摘要: A device includes a multistage filter and an elephant trap. The multistage filter has hash functions and an array. The multistage filter is operable to receive a packet associated with a candidate heavy network user and send the packet to the hash functions. The hash functions generate hash function output values corresponding to indices in the array. The elephant trap is connected to the multistage filter. The elephant trap includes a buffer and probabilistic sampling logic. The probabilistic sampling logic is operable to attempt to add information associated with the packet to the buffer a particular percentage of the time based in part on the result of the multistage filter lookup. The buffer is operable to hold information associated with the packet, counter information, and timestamp information.

    摘要: In one embodiment, a device (e.g., a transmitter) determines a level of error protection of each bit position within symbols of a particular constellation map used for modulation-based communication, and also determines priority levels of application data bits to be placed into a communication frame. Application data bits may then be placed into symbols of the communication frame, where higher priority application data bits are placed into bit positions with greater or equal levels of protection than bit positions into which lower priority application data bits are placed. The communication frame may then be transmitted to one or more receivers with an indication of how to decode the placement of the application data bits within the symbols. In another embodiment, the particular constellation map may be dynamically selected from a plurality of available constellation maps, such as based on communication channel conditions and/or applications generating the data.
