Abstract: A device includes a transceiver coupled to a processing device. The processing device is to determine a first time for executing an operation associated with a work execution agent of a plurality of work execution agent. The processing device is further to receive a latency measurement associated with the work execution agent responsive to transmitting the request. The latency measurement is calculated after executing a previous operation associated with the work execution agent at the device. The processing device is also to modify the first time to a second time for executing the operation responsive to receiving the latency measurement.

Abstract: A device includes a hardware block to perform a hardware process and internal logic coupled between a processing device, which executes instructions, and the hardware block. The internal logic can one of measure execution time or count clock cycles of at least a portion of the hardware process. The internal logic can further, in response to the measured execution time or the counted clock cycles satisfying a predetermined condition, provide data associated with the one of the execution time measurement or the clock cycles count to the processing device, the data being statistically indicative of a latency of data packets sent by the hardware process over a total time the hardware process executes.

Abstract: A synchronized communication system includes a plurality of network communication devices, one of which is designated as a root device and the others designated as slave devices. Each network communication device includes one or more ports and communications circuitry, which processes the communication signals received by the one or more ports so as to recover a respective remote clock from each of the signals. A synchronization circuit is integrated in the root device and provides a root clock signal, which is conveyed by clock links to the slave devices. A host processor selects one of the ports of one of the network communication devices to serve as a master port, finds a clock differential between the root clock signal and the respective remote clock recovered from the master port, and outputs, responsively to the clock differential, a control signal causing the synchronization circuit to adjust the root clock signal.

Abstract: A method for communication in a packet data network including at least first and second subnets interconnected by routers. The method includes defining at least first and second classes of link-layer traffic within the subnets, such that the link-layer traffic in the first class is transmitted among nodes in the network without loss of packets, while at least some of the packets in the second class are dropped in case of network congestion. The routers are configured by transmitting control traffic over the network in the packets of the second class. Data traffic is transmitted between the nodes in the first and second subnets via the configured routers in the packets of the first class.
