Abstract: Technologies for programming flexible accelerated network pipelines include a comping device with a network controller. The computing device loads a program binary file that includes a packet processing program and a requested hint section. The binary file may be an executable and linkable format (ELF) file with an extended Berkeley packet filter (eBPF) program. The computing device determines a hardware configuration for the network controller based on the requested offload hints and programs the network controller. The network controller processes network packets with the requested offloads, such as packet classification, hashing, checksums, traffic shaping, or other offloads. The network controller returns results of the offloads as hints in metadata. The packet processing program performs actions based on the metadata, such as forwarding, dropping, packet modification, or other actions. The computing device may compile an eBPF source file to generate the binary file. Other embodiments are described and claimed.

Abstract: Methods, apparatus, and systems for implementing in Network Interface Controller (NIC) flow switching. Switching operations are effected via hardware-based forwarding mechanisms in apparatus such as NICs in a manner that does not employ use of computer system processor resources and is transparent to operating systems hosted by such computer systems. The forwarding mechanisms are configured to move or copy Media Access Control (MAC) frame data between receive (Rx) and transmit (Tx) queues associated with different NIC ports that may be on the same NIC or separate NICs. The hardware-based switching operations effect forwarding of MAC frames between NIC ports using memory operations, thus reducing external network traffic, internal interconnect traffic, and processor workload associated with packet processing.
