    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 modular forwarding table scalability of a software cluster switch includes a plurality of computing nodes. Each of the plurality of computing nodes includes a global partition table (GPT) to determine an egress computing node for a network packet received at an ingress computing node of the software cluster switch based on a flow identifier of the network packet. The GPT includes a set mapping index that corresponds to a result of a hash function applied to the flow identifier and a hash function index that identifies a hash function of a hash function family whose output results in a node identifier that corresponds to the egress computing node to which the ingress computing node forwards the network packet. Other embodiments are described herein and claimed.

    摘要： A method and apparatus for selectively parking routers used for routing traffic in mesh interconnects. Various router parking (RP) algorithms are disclosed, including an aggressive RP algorithm where a minimum number of routers are kept active to ensure adequate network connectivity between active nodes and/or intercommunicating nodes, leading to a maximum reduction in static power consumption, and a conservative RP algorithm that favors network latency considerations over static power consumption while also reducing power. An adaptive RP algorithm is also disclosed that implements aspects of the aggressive and conservative RP algorithms to balance power consumption and latency considerations in response to ongoing node utilization and associated traffic. The techniques may be implemented in internal network structures, such as for single chip computers, as well as external network structures, such as computing clusters and massively parallel computer architectures. Performance modeling has demonstrated substantial power reduction may be obtained using the router parking techniques while maintaining Quality of Service performance objectives.
