    摘要: Technologies for supporting concurrency of a flow lookup table at a network device. The flow lookup table includes a plurality of candidate buckets that each includes one or more entries. The network device includes a flow lookup table write module configured to perform a displacement operation of a key/value pair to move the key/value pair from one bucket to another bucket via an atomic instruction and increment a version counter associated with the buckets affected by the displacement operation. The network device additionally includes a flow lookup table read module to check the version counters during a lookup operation on the flow lookup table to determine whether a displacement operation is affecting the presently read value of the buckets. Other embodiments are described herein and claimed.

    摘要: Technologies for distributed table lookup via a distributed router includes an ingress computing node, an intermediate computing node, and an egress computing node. Each computing node of the distributed router includes a forwarding table to store a different set of network routing entries obtained from a routing table of the distributed router. The ingress computing node generates a hash key based on the destination address included in a received network packet. The hash key identifies the intermediate computing node of the distributed router that stores the forwarding table that includes a network routing entry corresponding to the destination address. The ingress computing node forwards the received network packet to the intermediate computing node for routing. The intermediate computing node receives the forwarded network packet, determines a destination address of the network packet, and determines the egress computing node for transmission of the network packet from the distributed router.

    摘要: An embodiment may include circuitry to be comprised in a node. The node may be communicatively coupled to a network and may include a host processor to execute at least one communication protocol-related process. The circuitry may determine, at least in part, whether to buffer, at least in part, at least one packet received from the network based at least in part upon whether a weighted moving average exceeds a first threshold and is less than a second threshold. The average may be determined based at least in part upon one or more time intervals between one or more packet receptions from the network. Many alternatives, variations, and modifications are possible.

    摘要: Technologies for managing network flow lookups of a network device include a network controller and a target device, each communicatively coupled to the network device. The network device includes a cache for a processor of the network device and a main memory. The network device additionally includes a multi-level hash table having a first-level hash table stored in the cache of the network device and a second-level hash table stored in the main memory of the network device. The network device is configured to determine whether to store a network flow hash corresponding to a network flow indicating the target device in the first-level or second-level hash table based on a priority of the network flow provided to the network device by the network controller.
