  • Patent number: 10623311
    Abstract: 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.

  • Patent number: 10462059
    Abstract: The present disclosure describes a process and apparatus for improving insertions of entries into a hash table. A large number of smaller virtual buckets may be combined together and associated with buckets used for hash table entry lookups and/or entry insertion. On insertion of an entry, hash table entries associated with a hashed-to virtual bucket may be moved between groups of buckets associated with the virtual bucket, to better distribute entries across the available buckets to reduce the number of entries in the largest buckets and the standard deviation of the bucket sizes across the entire hash table.

  • Patent number: 10394784
    Abstract: Technologies for managing lookup tables are described. The lookup tables may be used for a two-level lookup scheme for packet processing. When the tables need to be updated with a new key for packet processing, information about the new key may be added to a first-level lookup table and a second-level lookup table. The first-level lookup table may be used to identify a handling node for an obtained packet, and the handling node may perform a second-level table lookup to obtain information for further packet processing. The first lookup table may be replicated on all the nodes in a cluster, and the second-level lookup table may be unique to each node in the cluster. Other embodiments are described herein and claimed.

    Abstract: 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.

  • Patent number: 10237171
    Abstract: 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.

  • Patent number: 10218647
    Abstract: Methods and apparatus to support multiple-writer/multiple-reader concurrency for software flow/packet classification on general purpose multi-core systems. A flow table with rows mapped to respective hash buckets with multiple entry slots is implemented in memory of a host platform with multiple cores, with each bucket being associated with a version counter. Multiple writer and reader threads are run on the cores, with writers providing updates to the flow table data. In connection with inserting new key data, a determination is made to which buckets will be changed, and access rights to those buckets are acquired prior to making any changes. For example, under a flow table employing cuckoo hashing, access rights are acquired to buckets along a full cuckoo path.
