Abstract: An apparatus includes an input interface to receive incoming packets from a first network device and an output interface to send outgoing packets to a second network device. Media access control security (MACsec) circuitry is coupled between the input interface and the output interface. Bypass flow-control (FC) circuitry is coupled between the input interface and the MACsec circuitry. The bypass FC circuitry is to detect an FC packet in the incoming packets and pass the FC packet passively to the output interface to enable end-to-end flow control directly between the first network device and the second network device.

Abstract: A communication apparatus includes a host interface, connected to a peripheral component bus so as to communicate with a CPU and a memory of a host computer. A network interface is connected to a network. Packet processing circuitry is configured to receive from a first interface a data packet including a set of one or more headers that include header fields having respective values, to identify, responsively to at least one of the header fields, a corresponding entry in a header modification table that specifies a header modification operation, to modify the set of headers in accordance with the header modification operation, to check whether the entry specifies an additional header modification operation, to output the modified set of headers if the entry does not specify an additional header modification operation, and, if the entry specifies an additional header modification operation, to feed-back the modified set of headers.

Abstract: A universal replaceable fan unit and method of reversing an airflow direction of a universal replaceable fan unit is provided. The universal replaceable fan unit includes a fan assembly designed to create an airflow from an intake end to an output end. The universal replaceable fan unit also includes a fan mounting that receives and secures the fan assembly in an operable position. The fan mounting includes a frame member and a securing member. The fan mounting is designed to allow the fan assembly to be moved between a first position defining a first airflow direction and a second position defining a second airflow direction. The first airflow direction is opposite the second airflow direction. The universal replaceable fan unit further includes an electrical connector removably attached to the fan assembly. The electrical connector allows electricity to be provided to the fan assembly for operation.

Abstract: Devices, methods, and systems are provided. In one example, a device is described to include a bandwidth-constrained resource and a controller that dynamically allocates a proportional consumption of storage to the bandwidth-constrained resource thereby enabling the bandwidth-constrained resource to provide bandwidth to a consuming entity. The controller may allocate the proportional consumption of the storage to the bandwidth-constrained resource based on a current state of the bandwidth-constrained resource.

Abstract: A network element one or more network ports, network time circuitry and packet processing circuitry. The network ports are configured to communicate with a communication network. The network time circuitry is configured to track a network time defined in the communication network. In some embodiments the packet processing circuitry is configured to receive a definition of one or more timeslots that are synchronized to the network time, and to send outbound packets to the communication network depending on the timeslots. In some embodiments the packet processing circuitry is configured to process inbound packets, which are received from the communication network, depending on the timeslots.

Abstract: A passive dual polarization unit and coherent transceiver and/or receiver including one or more passive dual polarization units are provided. An example passive dual polarization unit includes a polarization splitter configured to split an input signal into a TE mode and TM mode signals; TE/TM splitters each designed to split the TE/TM mode signals into first TE/TM signals and second TE/TM signals; a first TE signal polarization rotation component for receiving the first TE signal and providing a third TM signal having the same magnitude and time dependence as the first TE signal; a first TM signal polarization rotation component for receiving the first TM signal and providing a third TE signal having the same magnitude and time dependence as the first TM signal; and TE/TM couplers that couple the second TE/TM signals and the third TE/TM signals to generate output TE/TM signals.
