    摘要： Aspects of a method and system for determination and exchange of network timing information are provided. In this regard, for each network hop traversed by a packet, a propagation delay of said network hop may be determined. Moreover, the propagation delay, and/or a hop length calculated utilizing the propagation delay, may be appended to the packet. The packet may, for example, be a MMRP registration packet or a SRP reservation packet. The packet may be dropped in instances that the propagation delay and/or length of a one or more traversed network hops is outside a determined range. The hop length may be determined by multiplying the propagation delay by a speed of propagation on the hop. The speed of propagation may be determined based on the physical layer technology associated with the network hop. Digital rights management may be implemented for media communicated on the network hop based at least in part on the hop length or the propagation delay. In this regard, use of media content may be restricted to a specified location.

    摘要： A network switch is disclosed having at least one data port interface for receiving data and at least one link interface configured to transmit the data between the network switch and other network switches. The switch contains a data processor, having a segmented ring with a plurality of dedicated modules designed to process the data connected through that ring. A programmable ring dispatcher dispatches at least a portion of the data along a segmented ring to at least one of the dedicated modules. The data processor also has a command processor for processing commands received from the dedicated modules. The programmable ring dispatcher determines the first dedicated module to receive the portion of the data and that first dedicated module thereafter determines the next destination for the data potion. Because the dedicated modules can be added to or taken out the switch architecture based on the network environment, the switch is scalable and adaptable.

    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.
