Abstract
Examples described herein relate to technologies for reliable packet transmission. In some examples, a network interface includes circuitry to: receive a request to transmit a packet to a destination device, select a path for the packet, provide a path identifier identifying one of multiple paths from the network interface to a destination and Path Sequence Number (PSN) for the packet, wherein the PSN is to identify a packet transmission order over the selected path, include the PSN in the packet, and transmit the packet. In some examples, if the packet is a re-transmit of a previously transmitted packet, the circuitry is to: select a path for the re-transmit packet, and set a PSN of the re-transmit packet that is a current packet transmission number for the selected path for the re-transmit packet. In some examples, a network interface includes circuitry to process a received packet to at least determine a Path Sequence Number (PSN) for the received packet, wherein the PSN is to provide an order of packet transmissions for a path associated with the received packet, process a second received packet to at least determine its PSN, and based on the PSN of the second received packet not being a next sequential value after the PSN of the received packet, cause transmission of a re-transmit request to a sender of the packet and the second packet.
