    Abstract: A method includes detecting, by an accelerator of a networking device, a serial number of a first data packet is out of order with respect to a previous data packet within a first flow of data packets associated with a packet communication network, wherein the serial number is assigned to the first data packet according to a transport protocol. The method includes reconstructing context data associated with the first flow of data packets, wherein the context data comprises encoding information for encoding of data records containing data conveyed in payloads of data packets in the first flow of data packets according to a storage protocol. The method includes using, by the accelerator, the reconstructed context data in processing a data record associated with a second data packet within the first flow, wherein the second data packet is subsequent to the first data packet in the first flow of data packets.

    Abstract: A peripheral device coupled to a host includes a network interface, a packet processor, and a Data Processing Unit (DPU). The packet processor receives from a communication network, via the network interface, packets that originated from a source in an original order and received at the peripheral device in as order different from the original order. The packet processor splits the received packets into headers and payloads, sends the payloads for storage in a host memory and sends the headers without the payloads for storage in a DPU memory, and based on the headers produces a hint indicative of processing to be applied to the headers, by the DPU, for identifying the original order. Based on the hint, the DPU identifies the original order of the packets by applying the processing indicated by the hint to respective headers in the DPU memory, and notifies the host of the original order.

    Abstract: Embodiments are disclosed for facilitating an end-to-end link channel with one or more lookup tables for equalization. An example system includes a first transceiver and a second transceiver. The first transceiver includes a clock data recovery (CDR) circuit configured to receive communication data from a switch and to manage a lookup table associated with equalization of the communication data. The first transceiver also includes a first driver circuit communicatively coupled to the CDR circuit and configured to generate an electrical signal associated with the communication data. The second transceiver includes a second driver circuit, communicatively coupled to the first transceiver, that is configured to receive the electrical signal from the first transceiver and to modulate a laser source based on the electrical signal to generate an optical signal via the laser source.

    Abstract: A system includes a host processor, which has a host memory and is coupled to store data in a non-volatile memory in accordance with a storage protocol. A network interface controller (NIC) receives data packets conveyed over a packet communication network from peer computers containing, in payloads of the data packets, data records that encode data in accordance with the storage protocol for storage in the non-volatile memory. The NIC processes the data records in the data packets that are received in order in each flow from a peer computer and extracts and writes the data to the host memory, and when a data packet arrives out of order, writes the data packet to the host memory without extracting the data and processes the data packets in the flow so as to recover context information for use in processing the data records in subsequent data packets in the flow.
