Abstract: Embodiments provide techniques for delivering a paced stream of video data packets. One embodiment includes receiving a data stream of video data packets formatted according to a Society of Motion Picture and Television Engineers (SMPTE) standard. A desired rate of delivery for the video data packets at a gateway device is determined. Embodiments generate a padded data stream by inserting one or more pause frames in between the video data packets in the received data stream, based on the desired rate of delivery. The padded data stream is transmitted across a link to a network switch, to be transmitted to the gateway device.

Abstract: In one embodiment, a method for video traffic flow behavioral classification is implemented on a computing device and includes: receiving coarse flow data from a network router, where the coarse flow data includes summary statistics for data flows on the router, classifying the summary statistics to detect video flows from among the data flows, requesting fine flow data from the network router for each of the detected video flows, where the fine flow data includes information on a per packet basis, receiving the fine flow data from the network router, and classifying each of the detected video flows per video service provider in accordance with the information.

Abstract: In one embodiment, a method is described. The method includes: monitoring workloads of a plurality of application classes, each of the application classes describing services provided by one or more applications in a multi-tiered system and comprising a plurality of instantiated execution resources; estimating, for each of the application classes, a number of execution resources able to handle the monitored workloads, to simultaneously maintain a multi-tiered system response time below a determined value and minimize a cost per execution resource; and dynamically adjusting the plurality of instantiated execution resources for each of the application classes based on the estimated number of execution resources.

Abstract: Systems, methods, and computer program products relating to resilient transmission of a media stream over a communication network. A plurality of data packets are received over a communications network. The plurality of data packets relate to a first source video portion transformed using a geometric transform. The geometric transform is configured to modify a location of pixels in the first source video portion such that a plurality of adjacent pixels in the first source video portion are not adjacent after transformation. A received video portion is assembled based on the plurality of data packets. The received video portion is transformed, using an inverse of the geometric transform, to generate a second source video portion. The second source video portion and the first source video portion include a plurality of matching pixels.

Abstract: Real-time metadata about a plurality of video streams, and information associated with a directed stream, is received. The information includes a plurality of time segments, where time segments correspond to a respective video stream selected by a director for display in the directed stream during the time segment. Additionally, it is determined, based on the information, that the directed stream will display a first video stream during a first time segment. Further, a subsidiary stream is generated for a first group of users. This involves determining to substitute a second video stream for the first video stream during the first time segment, based on real-time metadata and further based on a first set of rules associated with the first group of users. When the first time segment begins, the second video stream is outputted for display in the subsidiary stream.

Abstract: A system for collision avoidance includes memory storing instructions which, when executed, cause one or more processors to perform determining a direction of flight of a first drone, causing broadcasting, in the direction of flight based, a beamformed signal of beacon frames, determining a new flight direction of the same first drone, in response to the new flight direction, causing broadcasting of the beacon frames in the new flight direction, detecting second beacon frames from a second drone associated with a direction from which the second beacon frames are arriving; in response, causing the first drone to perform, without input from a pilot, one or more of a change in elevation, heading, speed, or type of operation, directed toward causing the first drone to follow a flight path that is separated from the second drone.
