Abstract: Systems and techniques are provided for video frame playback scheduling. A presentation time for a frame of a video may be received. An offset for the frame of video may be determined based on succeeding frames of the video and Vsync pulse times. The presentation time for the frame of the video may be adjusted based on the offset to generate an adjusted presentation time that is closer to a halfway point between a first Vsync pulse and a second Vsync pulse than the presentation time. A cumulative time correction may be tracked based on adjustments made to the presentation times for frames of the video. A magnitude of the cumulative time correction may be determined to exceed the magnitude of a positive or negative threshold. The cumulative time correction may be added to or subtracted from based on the determination that the magnitude exceeds the positive or negative threshold.

Abstract: This disclosure provides systems, methods, and apparatus for mitigating the effects of interference signals on optical signals received at a direct-detection optical receivers. The optical receivers are capable of attenuating interference noise signals resulting from the interference between a transmitted optical signal transmitted from a transmitter to the optical receiver and one or more additional signals received at the optical receiver. The interference can be due to multi-path interference or due to in-band interference. The receivers include a tunable filter for filtering the received optical signal to remove the interference. A frequency offset module processes the received optical signal to determine a frequency offset indicative of the difference between the carrier frequencies of a modulated optical signal and an interference optical signal.

Abstract: In some implementations, a system and corresponding method for load balancing data traffic addressed to an anycast address include maintaining, by each of a plurality of load balancing (LB) devices a data structure including entries associated with application instances in a group of application instances served by the LB device. The frequency with which each served application instance is included in the data structure is indicative of a weight value associated with a capacity of the corresponding served application instance. Upon receiving a data packet, originally addressed to an anycast address, the LB device uses one or more header fields of the received data packet to identify a virtual Internet protocol (IP) address of one of the served application instances in the data structure maintained by the LB device. The LB device then forwards the data packet to the identified application instance.
