    Abstract: Technologies for packet flow classification on a computing device include a hash table including a plurality of hash table buckets in which each hash table bucket maps a plurality of keys to corresponding traffic flows. The computing device performs packet flow classification on received data packets, where the packet flow classification includes a plurality of sequential classification stages and fetch classification operations and non-fetch classification operations are performed in each classification stage. The fetch classification operations include to prefetch a key of a first received data packet based on a set of packet fields of the first received data packet for use during a subsequent classification stage, prefetch a hash table bucket from the hash table based on a key signature of the prefetched key for use during another subsequent classification stage, and prefetch a traffic flow to be applied to the first received data packet based on the prefetched hash table bucket and the prefetched key. The computing device handles processing of received data packets such that a fetch classification operation is performed by the flow classification module on the first received data packet while a non-fetch classification operation is performed by the flow classification module on a second received data packet.

    Abstract: Technologies for scalable packet reception and transmission include a network device. The network device is to establish a ring that is defined as a circular buffer and includes a plurality of slots to store entries representative of packets. The network device is also to generate and assign receive descriptors to the slots in the ring. Each receive descriptor includes a pointer to a corresponding memory buffer to store packet data. The network device is further to determine whether the NIC has received one or more packets and copy, with direct memory access (DMA) and in response to a determination that the NIC has received one or more packets, packet data of the received one or more packets from the NIC to the memory buffers associated with the receive descriptors assigned to the slots in the ring.

    Abstract: A round-robin network security system implemented by a number of peer devices included in a plurality of networked peer devices. The round-robin security system permits the rotation of the system security controller among at least a portion of the peer devices. Each of the peer devices uses a defined trust assessment ruleset to determine whether the system security controller is trusted/trustworthy. An untrusted system security controller peer device is replaced by another of the peer devices selected by the peer devices. The current system security controller peer device transfers system threat information and security risk information collected from the peer devices to the new system security controller elected by the peer devices.

    Abstract: Technologies for network packet processing include a computing device that receives incoming network packets. The computing device adds the incoming network packets to an input lockless shared ring, and then classifies the network packets. After classification, the computing device adds the network packets to multiple lockless shared traffic class rings, with each ring associated with a traffic class and output port. The computing device may allocate bandwidth between network packets active during a scheduling quantum in the traffic class rings associated with an output port, schedule the network packets in the traffic class rings for transmission, and then transmit the network packets in response to scheduling. The computing device may perform traffic class separation in parallel with bandwidth allocation and traffic scheduling. In some embodiments, the computing device may perform bandwidth allocation and/or traffic scheduling on each traffic class ring in parallel. Other embodiments are described and claimed.
