    摘要： Embodiments allow for the use of the SS modulation technique (and thus for significant reduction of EMI due to clock transmission) in scenarios involving tight synchronization requirements between two devices. In particular, embodiments can be used in high-speed communication networks (e.g., high-speed Ethernet) where a clock signal embedded in the data stream at the transmitter and recovered from the data stream at the receiver is the only source for synchronization between the transmitter and the receiver (i.e., no other synchronization channel available). Embodiments are also especially useful in communication systems utilizing echo cancellers.

    摘要： Aspects of a method and system for implementing redundancy for streaming data in audio video bridging networks are provided. Network resources may be reserved over a plurality of network paths. Reserved resources may be utilized for the transmission and/or reception of a corresponding plurality of data streams, wherein one or more of the streams may comprise redundant data. A plurality of data streams may be transmitted and/or received by a plurality of network interface hardware devices. Similarly, a plurality of data streams may be transmitted and/or received by a plurality of ports integrated into a single network interface hardware device. Each of the plurality of data streams may be assigned a unique identifier and the identifier of a first data stream may differ by one bit from an identifier of a data stream comprising data redundant to the first data stream.

    摘要： Aspects of a method and system for determining and securing proximity information over a network are provided. In this regard, data transmitted over a network may be time-stamped upon entering and/or exiting a network node. By taking the total time to travel between two network nodes and subtracting out any latency internal to one or more intermediate nodes, the time to traverse the physical links (the propagation time) between the two network nodes may be determined. Accordingly, if the speed at which data propagates over each link of the network is known, then a distance from the source node to the destination node may be determined. Additionally, aspects of the invention may enable one or more of authentication, validation, and encryption of timing and/or proximity information transmitted over a network.
