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: The present disclosure is directed to systems and methods for rate limiting network traffic generated by virtual machines (VMs) having multiple attached SR-IOV virtual functions. The network interface circuitry includes a plurality of offload circuits, each performing operations associated with a specific VF. Each VM attached to network interface circuitry is assigned a unique identifier. The unique identifier associated with a VM is inserted into the header of data packets originated by the VM. The packets are queued using a dedicated memory queue assigned to the VM. The aggregate data transfer rate for the VM is determined based upon counting the data packets originated by the VM and processed across the plurality of offload circuits. If the aggregate data transfer rate exceeds a data transfer rate threshold, traffic control circuitry limits the transfer of data packets from the memory queue associated with the VM to the plurality of offload circuits.

Abstract: Examples may include a method of instantiating a virtual machine; instantiating a virtual device to transmit data to and receive data from assigned resources of a shared physical device by receiving input data requesting assigned resources for the virtual device, allocating assigned resources to the virtual device based at least in part on the input data, and mapping a page location in an address space of the shared physical device for a selected one of the assigned resources to a page location in a memory-mapped input/output (MMIO) space of the virtual device; and assigning the virtual device to the virtual machine, the virtual machine to transmit data to and receive data from the physical device via the MMIO space of the virtual device.

Abstract: Technologies for remote direct memory access (RDMA) queue pair quality of service (QoS) management are disclosed. In the illustrative embodiment, several queue pairs associated with a virtual machine on a compute sled may be created in a network interface controller of the compute sled. A QoS parameter such as a class of service identifier or a weighting may be assigned to each queue pair such that each queue pair has a different available bandwidth. The compute sled may also predict future RDMA queue pair bandwidth usage and adjust RDMA queue pair bandwidth allocation based on the prediction.

Abstract: Devices and techniques for hardware accelerated packet processing are described herein. A device can communicate with one or more hardware switches. The device can detect characteristics of a plurality of packet streams. The device may distribute the plurality of packet streams between the one or more hardware switches and software data plane components based on the detected characteristics of the plurality of packet streams, such that at least one packet stream is designated to be processed by the one or more hardware switches. Other embodiments are also described.
