Abstract: Examples described herein relate to a reliable transport protocol for packet transmission using an Address Family of an eXpress Data Path (AF_XDP) queue framework, wherein the AF_XDP queue framework is to provide a queue for received packet receipt acknowledgements (ACKs). In some examples, an AF_XDP socket is to connect a service with a driver for the network device, one or more queues are associated with the AF_XDP socket, and at least one of the one or more queues comprises a waiting queue for received packet receipt ACKs. In some examples, at least one of the one or more queues is to identify one or more packets for which ACKs have been received. In some examples, the network device is to re-transmit a packet identified by a descriptor in the waiting queue based on non-receipt of an ACK associated with the packet from a receiver.

Abstract: Devices and techniques for accelerated packet processing are described herein. The device can match an action to a portion of a network data packet and accelerate the packet-processing pipeline for the network data packet through the machine by processing the action.

Abstract: Examples described herein relate to a network interface device comprising: a device interface; at least one processor; a direct memory access (DMA) device; and a packet processing circuitry. In some examples, the at least one processor, when operational, is configured to: in connection with a first operation: perform a format translation of a first descriptor from a first format associated with an emulated device to a second format associated with the packet processing circuitry and provide, to the packet processing circuitry, the translated first descriptor. In some examples, the at least one processor, when operational, is configured to: in connection with a second operation: perform a descriptor format translation of a second descriptor from the second format associated with the packet processing circuitry to the first format associated with the emulated software device and provide, to the emulated device, the translated second descriptor.

Abstract: Examples described herein relate to offload reliable transport management to a network interface device and store packets to be resent, based on received packet receipt acknowledgements (ACKs), into one or more kernel space queues that are also accessible in user space.
