Abstract: 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.

The routing parameters may indicate device capabilities, service class, quality measurements, latency, power usage or any combination thereof.

Abstract: 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.

Route selection may be based on availability of power for power sources of the communication devices. The selection of routes may be based on a current power consumption and/or a history of prior power consumption of the communication devices. The selection of a route which may require least power consumption may be optimized based on the availability of bandwidth.

Abstract: A network node in a vehicular network processes packets based on a prioritization scheme. The prioritization scheme uses packet type, priority, source, destination, or other information to determine a priority of the packets. Packets can be stored in one of multiple queues organized according to packet type, or other criteria. In some cases, only one queue is used. The packets are time stamped when put into a queue, and a time to live is calculated based on the timestamp. The time to live, as well as other factors such as packet type, packet priority, packet source, and packet destination can be used to adjust a packet's priority within the queue. Packets are transmitted from the queues in priority order. In some cases, the network node can identify a top-priority packet, and transmit the top priority packet without first storing the packet in the queue.
