  • Patent number: 10880850
    Abstract: In one aspect, a first device determines transmitter location information indicating a location for each of one or more transmitters that provide synchronization signals. The first device inserts the transmitter location information in a time synchronization IE and transmits the time synchronization IE to a second device. The second device receives the transmitter location information from the first device and determines one or more propagation delays of a synchronization signal received from a transmitter based on the transmitter location information received for the transmitter in the IE. The second device uses the determined one or more propagation delays to compensate for a timing difference between the first device and a transmitter of the synchronization signal.

  • Patent number: 10877670
    Abstract: Some embodiments of the invention provide a network forwarding element that can be dynamically reconfigured to adjust its data message processing to stay within a desired operating temperature or power consumption range. In some embodiments, the network forwarding element includes (1) a data-plane forwarding circuit (“data plane”) to process data tuples associated with data messages received by the IC, and (2) a control-plane circuit (“control plane”) for configuring the data plane forwarding circuit. The data plane includes several data processing stages to process the data tuples. The data plane also includes an idle-signal injecting circuit that receives from the control plane configuration data that the control plane generates based on the IC's temperature. Based on the received configuration data, the idle-signal injecting circuit generates idle control signals for the data processing stages.

  • Patent number: 10789199
    Abstract: Distributed computing systems, devices, and associated methods of packet routing are disclosed herein. In one embodiment, a computing device includes a field programmable gate array (“FPGA”) that includes an inbound processing path and outbound processing path in opposite processing directions. The inbound processing path can forward a packet received from the computer network to a buffer on the FPGA instead of the NIC. The outbound processing path includes an outbound multiplexer having a rate limiter circuit that only forwards the received packet from the buffer back to the computer network when a virtual port corresponding to the packet has sufficient transmission allowance. The outbound multiplexer can also periodically increment the transmission allowance based on a target bandwidth for the virtual port.
