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： Methods and apparatus for facilitating efficient Quality of Service (QoS) support for software-based packet processing by offloading QoS rate-limiting to NIC hardware. Software-based packet processing is performed on packet flows received at a compute platform, such as a general purpose server, and/or packet flows generated by local applications running on the compute platform. The packet processing includes packet classification that associates packets with packet flows using flow IDs, and identifying a QoS class for the packet and packet flow. NIC Tx queues are dynamically configured or pre-configured to effect rate limiting for forwarding packets enqueued in the NIC Tx queues. New packet flows are detected, and mapping data is created to map flow IDs associated with flows to the NIC Tx queues used to forward the packets associated with the flows.

摘要： Apparatus, methods, and systems for tuple space search-based flow classification using cuckoo hash tables and unmasked packet headers are described herein. A device can communicate with one or more hardware switches. The device can include memory to store hash table entries of a hash table. The device can include processing circuitry to perform a hash lookup in the hash table. The lookup can be based on an unmasked key include in a packet header corresponding to a received data packet. The processing circuitry can retrieve an index pointing to a sub-table, the sub-table including a set of rules for handling the data packet. Other embodiments are also described.

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.
