Abstract: A method for data communication includes submitting from a host processor to a network interface controller (NIC) during a first time period first work items instructing the NIC to transmit over a network packets containing respective data. The first work items include pointer-based work items, which contain a pointer to the respective data in a memory of the host processor, and inline work items, which contain the respective data. The performance of the NIC is measured in transmitting the packets during the first time period. During a second time period, subsequent to the first time period, the host processor submits second work items to the NIC while deciding automatically, under control of software running on the host processor and based on the measured performance during the first time period, how many of the second work items are to be pointer-based and how many are to be inline work items.

Abstract: A Network Interface (NI) includes a host interface, which is configured to receive from a host processor of a node one or more work requests that are derived from an operation to be executed by the node. The NI maintains a plurality of work queues for carrying out transport channels to one or more peer nodes over a network. The NI further includes control circuitry, which is configured to accept the work requests via the host interface, and to execute the work requests using the work queues by controlling an advance of at least a given work queue according to an advancing condition, which depends on a completion status of one or more other work queues, so as to carry out the operation.

Abstract: A host computer connects to a data network via a host interface to a network interface controller A sideband interface connects the network interface controller to a baseboard management controller having a management network port for connection to a management network. A path is established in the network interface controller between the host interface the basement management controller via the sideband interface of the network interface controller to conduct data selectively between the management network and either the host central processing unit and the or internally in the network interface controller.

Abstract: A method includes, in a processor, receiving first and second operations for periodic execution with respective specified time periods. Respective actual time periods having no common divisor are derived from the specified time periods. The first and second operations are executed periodically with the respective actual time periods.

Abstract: Communication apparatus includes a host interface and a network interface, which receives at least first and second redundant packet streams, each including a sequence of data packets, which include headers containing respective packet sequence numbers and data payloads of a predefined, fixed size containing respective slices of the data segment. Redundant first and second copies of each slice are transmitted in respective packets in the first and second packet streams. Packet processing circuitry receives the data packets from the network interface, maps the data packets in both the first and second packet streams, using the packet sequence numbers, to respective addresses in a buffer, and writes the data payloads to the respective addresses via the host interface while eliminating redundant data so that the buffer contains exactly one copy of each slice of the data segment, ordered in accordance with the packet sequence numbers.

Abstract: Network communication is carried out by transmitting messages in accordance with a predefined data exchange protocol among nodes that include a master domain and a plurality of client domains. A list of expected messages has a tail portion in the master domain and respective head portions in the client domains. A search is conducted for a match between the tag of a received message to tags in a list of unexpected messages that is maintained in the master domain. Upon a failure to find the match the receive is added to the list of expected messages. If a match is found then data in the message is written into a data buffer.

Abstract: Networking systems and methods of assembly are described that provide a modular system that includes a main networking box and a detachable module. The main networking box and the detachable module are configured to be connected to each other on a datacenter rack via board-to-board connectors to provide the desired connections to the network, but can also be unlocked and detached from each other, such as to allow the main networking box to be replaced. In this way, the main networking box can be replaced in the field to provide a repair, or the detachable module can be replaced to provide a different connection type, without requiring the other component and/or its connections to be disturbed.

Abstract: A method for steering packets includes receiving a packet and determining parameters to be used in steering the packet to a specific destination, in one or more initial steering stages, based on one or more packet specific attributes. The method further includes determining an identity of the specific destination of the packet in one or more subsequent steering stages, governed by the parameters determined in the one or more initial stages and one or more packet specific attributes, and forwarding the packet to the determined specific destination.

Abstract: An apparatus and method of assembly are described that provide an improved printed circuit board (PCB) assembly for an electro-optical interface, where more accurate positioning and alignment of electro-optical components can be achieved in an active part of the PCB assembly that is used for the electro-optical interface to meet tighter tolerances in an easier and more cost efficient manner. In particular, a photonic integrated circuit (PIC) is received in a cavity defined in a PCB that includes conductive elements for transmitting electrical signals. An optoelectronic transducer is connected to the PIC to convert between the optical signals and the corresponding electrical signals, and an optical coupler is secured to the optoelectronic transducer and supported by the PIC and/or PCB, where the optical coupler is configured to transmit the optical signals between the optoelectronic transducer and an optical fiber.
