Abstract: System, methods, and devices for sharing time information between machines are provided. In one example, a system includes a Precision Time Protocol (PTP) Hardware Clock (PHC) and an application. The application receives time information from the PHC along with contextual metadata associated with the time information, analyzes the contextual metadata associated with the time information, and determines a context in which the PHC is disciplined. The context in which the PHC is disciplined may control a manner in which the application uses the time information.

Abstract: A Direct Memory Access (DMA) device includes an interface and a DMA engine. The interface is configured to communicate with a first memory and with a second memory. The DMA engine is configured to (i) receive a request to transfer data between the first memory and the second memory in accordance with a pattern of offsets to be accessed in the first memory or in the second memory, and (ii) transfer the data in accordance with the request.

Abstract: A method for data transfer includes transmitting a sequence of data packets from a first computer over a network to a second computer in a single RDMA data transfer transaction. Upon receipt of a second packet in the sequence without previously having received the first packet, the second computer sends a NAK packet over the network to the first computer, indicating that the first packet was not received. A retransmission mode is selected responsively to the type of the transaction, such that when the transaction is of a first type, the first packet is retransmitted from the first computer to the second computer in response to the NAK packet without retransmitting the second packet, and when the transaction is of a second type, both the first and second packets are retransmitted from the first computer to the second computer in response to the NAK packet.

Abstract: A networking device and system are described, among other things. An illustrative system is disclosed to include a packet parser and a state machine that includes a NULL header state. The packet parser references the state machine to enter the NULL header state automatically in response to parsing a packet header of a predetermined type and then, while in the NULL header state, analyzes a subsequent set of bytes without advancing a parser pointer.

Abstract: A method includes receiving a network packet into a hardware pipeline of a network device; parsing and retrieving information of the network packet; determining, by the hardware pipeline, a packet-processing action to be performed by matching the information to a data structure of a set of flow data structures; sending, by the hardware pipeline, an action request to a programmable core, the action request being populated with data to trigger the programmable core to execute a hardware thread to perform a job, which is associated with the packet-processing action and that generates contextual data; retrieving the contextual data updated by the programmable core; and integrating the contextual data into performing the packet-processing action.

Abstract: An apparatus, system, and method include, for each of two or more switches of a communication network, identifying a set of routing paths from the switch to a destination node based on a topology associated with the communication network. The set of routing paths include a first subset of routing paths and a second subset of routing paths. The topology includes an indication of a convergence of the first subset of routing paths at a node between the switch and the destination node. The apparatus, system, and method include allocating a data flow to a first routing path of the first subset of routing paths and a second routing path of the second subset of routing paths according to a target data flow rate common to the first routing path and the second routing path.

Abstract: A System-On-Chip (SoC) includes a set of registers, a processor, and Out-Of-Order Write (OOOW) circuitry. The processor is to execute instructions including write instructions. After issuing a first write instruction to any of the registers in the set, the processor is to await an acknowledgement for the first write instruction before issuing a second write instruction to any of the registers in the set. The OOOW circuitry is to identify the write instructions issued by the processor to the registers in the set, to perform the identified write instructions in the registers irrespective of acknowledgements from the registers, and to send to the processor imitated acknowledgements for the identified write instructions.

Abstract: A system can include an optical receiver. The optical receiver can have an optical delay component and at least one electrical component (e.g., diode, resistor and/or transistor) operatively coupled to (e.g., integrated within) the optical delay component. The system can further include a processing device, operatively coupled to a memory, that can tune an amount of optical delay implemented by the optical delay component in a low loss and/or low dispersion manner. For example, the processing device can adjust, based on optical delay tuning data (e.g., built-in self-test (BIST) data), the at least one electrical component to modify at least one property of the at least one optical delay component.
