Abstract: In one embodiment, the method of carrier handoff includes receiving a measurement report from a mobile providing information regarding path loss as measured at the mobile for a serving one of the multiple carriers on the downlink. The serving carrier is the carrier over which the mobile communicates on the uplink. The method further includes selectively sending an instruction to the mobile to handoff to a non-serving one of the multiple carriers depending on whether a threshold requirement associated with the serving carrier has been met. Meeting the threshold requirement is based on the received measurement report, and each of the multiple carriers has an associated threshold requirement.

Abstract: Technology which facilitates a reduction in time of the presentation of video content after a viewer changes channels is described. Frames of a video stream associated with a channel are analyzed to identify locations of access points in the video stream prior to relaying the video stream to a presentation device. Information indicating the locations of access points is stored. The video stream is then time shifted on a continuous basis and is transmitted to the presentation device which made the request for as long as the presentation device remains tuned to the channel corresponding to the request. A first available frame on or before an access point of the time shifted video stream is selected based on the stored information, which is used to commence the transmission of the time shifted video to the presentation device, which facilitates a more immediate presentation of video content.

Abstract: A coherent optical receiver for a data-frame format in which a data frame has two or more pilot-symbol blocks, each having a cyclic prefix or suffix, and one or more payload-symbol blocks, each of which is concatenated with at least one adjacent block without a guard interval between them. The receiver uses optical signals corresponding to the pilot-symbol blocks to perform data-frame synchronization, frequency-offset correction, and channel-estimation procedures, which are robust even in the presence of certain transmission impairments. The receiver applies block-overlap processing with a sliding window to recover the payload data in a manner that substantially cancels the adverse effects of inter-block interference caused by the absence of guard intervals in the payload portion of the data frame.

Abstract: An access node of a communication system is configured to control crosstalk between channels of the system. Vectoring circuitry in the access node estimates crosstalk between channels of the system, generates a compressed representation of the crosstalk estimates, and generates compensated signals based on the compressed representation of the crosstalk estimates. The compressed representation comprises a value array and an index array, with the value array comprising selected values from each of a plurality of rows of a matrix representation of the crosstalk estimates, and the index array identifying locations of the selected values in the matrix representation of the crosstalk estimates. The compensated signals may be pre-compensated signals or post-compensated signals.

Abstract: A crossconnect for asynchronous OTN signals operates synchronously internally at an internal clock rate. Received OTN signals are synchronized to an internal frame format by stuffing. The synchronized signals are parallelized and switched with a switching matrix comprising synchronously operating integrated circuits that operate at the internal clock rate. At the output, the synchronized signals are again destuffed and are transmitted again at the original bit rate.

Abstract: Systems and techniques to set a new service rate for one or more queues of a router and a new power consumption level for a router is disclosed. The queues are configured to store data packets awaiting transmission from the router. The setting of the new service rate or rates and new power level is based on a service rate of the one or more queues and a power consumption level of the router. The techniques disclosed further include resetting a new service rate for the one or more queues of the router and a new power consumption level of the router. The resetting of the new service rate or rates and new power level is based on a service rate of the one or more queues and a power consumption level of the router. The setting and resetting steps are based differently on the power consumption level of the router.

Abstract: In one embodiment, a method for detecting malicious software agents, such as domain-flux botnets. The method applies a co-clustering algorithm on a domain-name query failure graph, to generate a hierarchical grouping of hosts based on similarities between domain names queried by those hosts, and divides that hierarchical structure into candidate clusters based on percentages of failed queries having at least first- and second-level domain names in common, thereby identifying hosts having correlated queries as possibly being infected with malicious software agents. A linking algorithm is used to correlate the co-clustering results generated at different time periods to differentiate actual domain-flux bots from other domain-name failure anomalies by identifying candidate clusters that persist for relatively long periods of time.

Abstract: Systems and methods are disclosed that monitor the speed that a mobile device is traveling, such as when the user of the mobile device is driving or riding in a vehicle. A speed monitoring system described herein receives a request from a third party to monitor a speed of a mobile device. The system periodically queries a mobile network for a location of the mobile device over a time period, and receives responses from the mobile network indicating locations of the mobile device. The system then determines a speed of the mobile device based on the locations indicated during the time period, and may determine the speed limit the roadway the mobile device is traveling on. The system then sends a notification message to the third party that includes an indication of the speed of the mobile device and possibly the speed limit.
