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.

In one embodiment, the present invention includes a method for obtaining file information regarding a file to be downloaded from a remote location to a computing device, creating at least one empty file in a destination storage based on the file information and communicating block information regarding the empty file to a network interface, and receiving a data packet of the file in the network interface and directly sending a payload of the data packet from the network interface to the destination storage according to the block information, while a host processor of the computing device is in a low power state. Other embodiments are described and claimed.

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:
Methods and apparatus for implementing active interconnect link power management using an adaptive low-power link-state entry policy. The power state of an interconnect link or fabric is changed in response to applicable conditions determined by low-power link-state entry policy logic in view of runtime traffic on the interconnect link or fabric. The low-power link-state policy logic may be configured to include consideration of operating system input and Quality of Service (QoS) requirements for applications and devices employing the link or fabric, and device latency tolerance requirements.

Embodiments of an apparatus, system and method are described for input/output (I/O) device assisted platform power management. An apparatus may comprise, for example, power management logic operative to receive idle duration information from one or more input/output (I/O) devices and to modify a power state for one or more components based on the idle information. Other embodiments are described and claimed.
摘要:
Systems and methods may provide for aggregating a first idle duration from a first device associated with a platform and a second idle duration from a second device associated with the platform. Additionally, an idle state may be selected for the platform based at least in part on the first idle duration and the second idle duration. In one example, the idle durations are classified as deterministic, estimated or statistical.

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.
