Abstract: This disclosure describes techniques for performing communications between devices using various aspects of Ethernet standards. As further described herein, a protocol is disclosed that may be used for communications between devices, where the communications take place over a physical connection complying with Ethernet standards. Such a protocol may enable reliable and in-order delivery of frames between devices, while following Ethernet physical layer rules, Ethernet symbol encoding, Ethernet lane alignment, and/or Ethernet frame formats.

Abstract: A highly-programmable access node is described that can be configured and optimized to perform input and output (I/O) tasks, such as storage and retrieval of data to and from storage devices (such as solid state drives), networking, data processing, and the like. For example, the access node may be configured to execute a large number of data I/O processing tasks relative to a number of instructions that are processed. The access node may be highly programmable such that the access node may expose hardware primitives for selecting and programmatically configuring data processing operations. As one example, the access node may be used to provide high-speed connectivity and I/O operations between and on behalf of computing devices and storage components of a network, such as for providing interconnectivity between those devices and a switch fabric of a data center.

Abstract: Techniques are described for providing a scaled-out transport supported by interconnected data processing units (DPUs) that operates as a single system bus connection proxy for device-to-device communications within a data center. As one example, this disclosure describes techniques for providing a Peripheral Component Interconnect Express (PCIe) proxy for device-to-device communications employing the PCIe standard. The disclosed techniques include adding PCIe proxy logic on top of a host unit of a DPU to expose a PCIe proxy model to application processors, storage devices, network interface controllers, field programmable gate arrays, or other PCIe endpoint devices. The PCIe proxy model may be implemented as a physically distributed Ethernet-based switch fabric with PCIe proxy logic at the edge and fronting the PCIe endpoint devices. The interconnected DPUs and the distributed Ethernet-based switch fabric together provide a reliable, low-latency, and scaled-out transport that operates as a PCIe proxy.
