A virtual machine (VM) can provision a region of memory for a queue to receive packet header, packet payload, and/or descriptors from the network interface. A virtual switch can provide a routing rule to a network interface to route a received packet header, packet payload, and/or descriptors associated with the VM to the provisioned queue. A direct memory access (DMA) transfer operation can be used to copy the received packet header, packet payload, and/or descriptors associated with the VM from the network interface to the provisioned queue without copying the packet header or payload to an intermediate buffer and from the intermediate buffer to the provisioned queue. A DMA operation can be used to transfer a packet or its descriptor from the provisioned queue to the network interface for transmission.

Techniques for network packet classification, transmission and receipt

Particular embodiments described herein provide for a network element that can be configured to receive a link monitoring message, determine one or more resources associated with the link monitoring message, determine a status of each of the one or more resources, and send a response that provides an indication of the status of each of the one or more resources. In an example, the link monitoring is part of a bidirectional forwarding detection packet.

Resource monitoring

Methods and systems of managing radio based power may include a mobile platform having a plurality of radios and logic to detect changes in location for the mobile platform. The logic may also deactivate at least one of the plurality of radios in response to the changes in location. The changes in location may be detected based on location information obtained from one or more active radios in the plurality of radios and connection losses with respect to active radios in the plurality of radios.

Radio based location power profiles

Examples include techniques for a configuration mechanism of a virtual switch. Example techniques include monitoring a database including parameter to configure a virtual switch at a computing platform hosting a plurality of virtual machines or containers. Changes to one or more parameters may cause changes in allocations of computing resources associated with supporting the virtual switch.

Techniques for a configuration mechanism of a virtual switch

An input/output (I/O) device arranged to receive an information element including a payload, determine control information from the information element, classify the information element based on the control information, and issue a write to one of a plurality of computer-readable media based on the classification of the information element, the write to cause the payload to be written to the one of the plurality of computer-readable media.

Techniques for cache delivery

Systems and methods for tracking cache line consumption. An example system may comprise: a cache comprising a plurality of cache entries for storing a plurality of cache lines; a processing core, operatively coupled to the cache; and a cache control logic, to: responsive to detecting an update operation with respect to a cache line of the plurality of cache lines, set a cache line access tracking flag associated with the cache line to a first state indicating that the cache line has been produced; and responsive to detecting a read operation with respect to the cache line, set the cache line access tracking flag associated with the cache line to a second state indicating that the cache line has been consumed.

Tracking cache line consumption

Technologies for filtering network packets on ingress include a network interface controller (NIC) to retrieve classification filters based on packet classification identifying information of a network packet received by the NIC, wherein each of the classification filters is usable to identify rules for identifying any operations to be performed on at least a portion of the received network packet. The NIC is further configured to compare the first classification filter to the packet classification identifying information to determine whether the determined packet classification identifying information meets criteria of the first classification filter. Additionally, the NIC is configured to associate a classification filter identifier of the first classification filter with the received network packet and send the received network packet and the classification filter identifier of the first classification filter to a processor of an apparatus associated with the NIC. Other embodiments are described herein.

Technologies for filtering network packets on ingress

An embodiment may include circuitry to be included, at least in part, in at least one node in a network. The circuitry may generate, at least in part, and/or receive, at least in part, at least one packet. The packet may be received, at least in part, by at least one switch node in the network. The switch node may designate, in response at least in part to the packet, at least one port of the switch node to be used to facilitate, at least in part, establishment, at least in part, of at least one path for propagation of at least one flow between at least two other nodes in the network. The packet may be generated based at least in part upon (1) at least one application classification, (2) at least one allocation request, and (3) network resource availability information.

Generating and/or receiving at least one packet to facilitate, at least in part, network path establishment

Examples may include a host computing platform having a multi-core processor capable of supporting a host operating system and a plurality of virtual machines (VMs). Support may include processing elements or cores for the multi-core processor being capable of separately supporting individual VMs. The individual VMs may be capable of executing separate applications used to process packets for a service chain flow. In some examples, techniques for routing the packets for the service chain flow between the individual VMs may include distributing at least some switch logic between the individual VMs.
