摘要： Techniques to secure a time sensitive network are described. An apparatus may establish a data stream between a first device and a second device in a network domain, the network domain includes a plurality of switching nodes, receive messages from the first device by the second device in the network domain, the messages to comprise time information to synchronize a first clock for the first device and a second clock for the second device to a network time for the network domain, update a correction field for a received message with a residence time and time delay value by the second device, determine whether the updated message is benign or malicious, update the correction field for the updated message with an inference time when the updated message is benign, and prevent relay of the updated message to other devices in the network domain when the updated message is malicious.

摘要： Time recovery techniques are described. A method comprises receiving messages from the first device by the second device in the first network domain, the messages to comprise time information to synchronize a first clock for the first device and a second clock for the second device to a network time, determining the second clock is to recover the network time for the second device without new messages from the first device, retrieving a first set of timestamps previously stored for events in the first network domain using the network time from the second clock, retrieving a second set of timestamps previously stored for the events in the first network domain using a redundant time from a third clock, where the third clock is not synchronized with the first and second clocks, and recovering the network time using a regression model and the redundant time from the third clock.

摘要： Systems and methods of generating a synchronized media content presentation using a plurality of media output systems communicably coupled to a respective plurality of network connected platforms are provided. A first network connected platform receives an IEEE 802.1AS master timing signal generated by “Grand Master” timing circuitry disposed in a second network connected platform. IEEE 802.1AS application service circuitry disposed in the first network connected platform determines an offset between a local timing signal and the receive master timing signal. Talker circuitry disposed in the first network connected platform synchronizes a media content presentation to the master timing signal and communicates a media/master timing signal synchronization signal to each of the network connected platforms. The media/master timing signal synchronization signal includes data representative of a media start location and a media start time referenced to the master timing signal.

摘要： Techniques to output a media stream, capture a media stream, or synchronize the output or capture of the media stream at a specified time are described. A media stream output or capture apparatus may include a media processor to receive a media stream to output or a request to capture a media stream and a start time. A buffer generator may be included to generate an input or an output buffer and a media mixer may be included to mix the media stream into the output buffer at the start time or capture the media stream from the input buffer at the start time.

摘要： Various techniques for reducing power consumption of a computing device are described herein. In one example, a method includes detecting that the computing device is to execute a first operation for a first hardware component. The method can also include determining that the computing device is not to execute a second operation for a second hardware component during a period of time. Furthermore, the method can include loading operation data corresponding to the first operation into a processor cache from a non-volatile storage device and detecting that the first operation is not to request memory data from a volatile storage device. The method can also include removing power from at least one storage device.
