Abstract: Examples include registering a device driver with an operating system, including registering available hardware offloads. The operating system receives a call to a hardware offload, inserts a binary filter representing the hardware offload into a hardware component and causes the execution of the binary filter by the hardware component when the hardware offload is available, and executes the binary filter in software when the hardware offload is not available.

Abstract: Examples include techniques to use a network service header to monitor Quality of Service (QoS). Examples include implementation of a QoS stamping policy to monitor one or more QoS fields of a network packet routed through nodes arranged to separately provide individual service functions included in a service function chain. A determination is made as to whether the QoS stamping information indicates a consistent QoS configuration in the one or more QoS fields of the network packet at node ingress or node egress of the network packet as routed through the nodes.

Abstract: In one embodiment, a system comprises a network interface controller to determine context information associated with a data packet. The network interface controller may select a receive descriptor profile from a plurality of receive descriptor profiles based upon a first portion of the context information and build a receive descriptor for the data packet based upon a second portion of the context information and the selected receive descriptor profile.

Abstract: Technologies for reordering network packets on egress include a network interface controller (NIC) configured to associate a received network packet with a descriptor, generate a sequence identifier for the received network packet, and insert the generated sequence identifier into the associated descriptor. The NIC is further configured to determine whether the received network packet is to be transmitted from a compute device associated with the NIC to another compute device and insert, in response to a determination that the received network packet is to be transmitted to the another compute device, the descriptor into a transmission queue of descriptors. Additionally, the NIC is configured to transmit the network packet based on position of the descriptor in the transmission queue of descriptors based on the generated sequence identifier. Other embodiments are described herein.

Abstract: Technologies for filtering network packets on ingress include a network interface controller (NIC) to retrieve classification filters based on packet classification identifying information of a network packet received by the NIC, wherein each of the classification filters is usable to identify rules for identifying any operations to be performed on at least a portion of the received network packet. The NIC is further configured to compare the first classification filter to the packet classification identifying information to determine whether the determined packet classification identifying information meets criteria of the first classification filter. Additionally, the NIC is configured to associate a classification filter identifier of the first classification filter with the received network packet and send the received network packet and the classification filter identifier of the first classification filter to a processor of an apparatus associated with the NIC. Other embodiments are described herein.

Abstract: One embodiment provides a network device. The network device includes a a processor including at least one processor core; a network interface configured to transmit and receive packets at a line rate; a memory configured to store a scheduler hierarchical data structure; and a scheduler module. The scheduler module is configured to prefetch a next active pipe structure, the next active pipe structure included in the hierarchical data structure, update credits for a current pipe and an associated subport, identify a next active traffic class within the current pipe based, at least in part, on a current pipe data structure, select a next queue associated with the identified next active traffic class, and schedule a next packet from the selected next queue for transmission by the network interface if available traffic shaping token bucket credits and available traffic class credits are greater than or equal to a next packet credits.
