Abstract: Embodiments are disclosed for a coupling element with embedded modal filtering for a laser and/or a photodiode. An example system includes a laser and an optical coupling element. The laser is configured to emit an optical signal. The optical coupling element is configured to receive the optical signal emitted by the laser. The optical coupling element is also configured to be connected to an optical fiber such that, in operation, the optical signal is transmitted from the laser to the optical fiber via the optical coupling element. Furthermore, the coupling element comprises a tapered section that provides modal filtering of the optical signal.

Abstract: Apparatus for data communication includes a network interface for connection to a packet data network and a host interface for connection to a host computer, which includes a central processing unit (CPU) and a host memory. Packet processing circuitry receives, via the host interface, from a kernel running on the CPU, associations between multiple remote direct memory access (RDMA) sessions and multiple different User Datagram Protocol (UDP) 5-tuple, which are assigned respectively to the RDMA sessions, and receives from an application running on the CPU a request to send an RDMA message, using a selected group of one or more of the RDMA sessions, to a peer application over the packet data network, and in response to the request, transmits, via the network interface, one or more data packets using a UDP 5-tuple that is assigned to one of the RDMA sessions in the selected group.

Abstract: A computer system includes a volatile memory and at least one processor. The volatile memory includes a protected storage segment (PSS) configured to store firmware-authentication program code for authenticating firmware of the computer system. The at least one processor is configured to receive a trigger to switch to a given version of the firmware, to obtain, in response to the trigger, a privilege to access the PSS, to authenticate the given version of the firmware by executing the firmware-authentication program code from the PSS, to switch to the given version of the firmware upon successfully authenticating the given version, and to take an alternative action upon failing to authenticate the given version.

Abstract: Systems, data processing systems, and methods, among other things, are disclosed. An illustrative system includes an encryption orchestrator that analyzes a packet, obtains a tenant identifier (ID) from the packet, determines whether a tenant associated with the tenant ID currently has sufficient encryption credit available, and enables an encryption resource to process the packet using an encryption key associated with the tenant ID in response to determining that the tenant associated with the tenant ID currently has sufficient encryption credit available.
