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.

Abstract: Examples described herein relate to an apparatus comprising: a descriptor format translator accessible to a driver. In some examples, the driver and descriptor format translator share access to transmit and receive descriptors. In some examples, based on a format of a descriptor associated with a device differing from a second format of descriptor associated with the driver, the descriptor format translator is to: perform a translation of the descriptor from the format to the second format and store the translated descriptor in the second format for access by the device. In some examples, the device is to access the translated descriptor; the device is to modify content of the translated descriptor to identify at least one work request; and the descriptor format translator is to translate the modified translated descriptor into the format and store the translated modified translated descriptor for access by the driver.

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.
