Abstract: A system including a receiver and a processing pipeline. The receiver is configured to generate a data block by encapsulating a data packet in a header portion and a tail portion that do not include valid information bits. The processing pipeline is configured to, in a first processing stage, store the data block, and store, separately from the data block, additional information associated with the data block. The processing pipeline is further configured to, without modifying a length of the data block, either add bits to the header portion or the tail portion to increase the length of the data packet or subtract bits from the data packet to decrease the length of the data packet, and modify the additional information in accordance with the bits added to the header portion or the tail portion or the bits subtracted from the data packet.

Abstract: Systems and methods are provided for counting a number of received packets and a number of bytes contained in the received packets. A system includes a first memory disposed in an integrated circuit, the first memory being configured as a first combination counter having a first set of bits for storing a subtotal of received packets, and a second set of bits for storing a subtotal of bytes contained in the received packets. A second memory is external to the integrated circuit. The second memory is configured to store a total number of received packets and a total number of bytes contained in the received packets. Update circuitry is configured to update the total number of packets stored in the second whenever either of the first set of bits or the second set of bits overflows in the first memory.

Abstract: A network device that processes a stream of packets has an ingress front end. The ingress front end determines whether the packets are handled in a bounded latency path or in a best-effort path. The bounded latency path packets are granted a resource with a higher priority than the best-effort path packets. As the packets are processed through a number of processing stages, with processing engines, the bounded latency packets are processed within a period of time corresponding to a guaranteed rate. Resources are granted to the best-effort path packets only when the processing engines determine that the resource grant will not impact the latency bounds with respect to the first packets.

An example gas turbine engine frame may include a generally annular outer casing disposed coaxially about a hub; a plurality of circumferentially spaced apart struts joined to the hub and the outer casing, individual struts extending radially outwardly from the hub to the outer casing; and a stiffening rail monolithically formed with the outer casing circumferentially between two of the struts. The stiffening rail may extend radially inward beyond the inner surface of the outer casing between the struts.

Abstract: The disclosed embodiments relate to a packet-processing system. This system includes an input which is configured to receive packets, wherein the packets include control-message (CM) packets and traffic packets. It also includes a pipeline to process the packets, wherein the pipeline includes access points for accessing an engine which services requests for packets, wherein CM packets and traffic packets access the engine through different access points. The system additionally includes an arbiter to schedule packets entering the pipeline. While scheduling the packets, the arbiter is configured to account for empty slots in the pipeline to ensure that when CM packets and traffic packets initiate accesses to the engine through different access points, the accesses do not cause an overflow at an input queue for the engine.

Abstract: The invention is directed to a switch assembly which can be used in situation in which the switch accommodates the flow of high voltage current. An actuator assembly with moveable contacts is moved by a motor driven armature. The moveable contacts are in electrical engagement with the stationary contacts when the armature is in the first position, and the moveable contacts are spaced from the stationary contacts when the armature is in the second position. By angling the stationary contacts and moveable contacts, the linear motion of the armature causes the moveable contacts to move across the surface of the stationary contacts as the armature approaches the first position. As all of the movements of the assembly are in a direction parallel to the axis of the armature, the assembly can be manufactured and operated reliably in a relatively small space. In addition, the linear movement on the angled contact provides for a positive electrical connection even in adverse environments.
