Abstract: In certain exemplary embodiments, a switching device is provided, including an input interface configured to communicate with a packet source, an output interface configured to communicate with a packet destination, and packet processing circuitry. The packet processing circuitry is configured to receive a plurality of packets from the packet source via the input interface, each of the plurality of packets being associated with a packet descriptor, at least one of the packet descriptors being a transmission time packet descriptor including a desired physical transmission time for the packet associated with the transmission time packet descriptor, to receive an indication of a clock time, and for each packet associated with a transmission time packet descriptor, to physically transmit the packet associated with the transmission time packet descriptor, via the output interface, at a clock time corresponding to the desired physical transmission time. Related apparatus an methods are also provided.
