Abstract: In some examples, for process-to-process communication, such as in function linking, a virtual channel can be provisioned to provide virtual machine to virtual machine communications. In response to a transmit request from a source virtual machine, the virtual channel can cause a data copy from a source buffer associated with the source virtual machine without decryption or encryption. The virtual channel provisions a key identifier for the copied data. The destination virtual machine can receive an indication data is available and can cause the data to be decrypted using a key accessed using the key identifier and source address of the copied data. In addition, the data can be encrypted using a second, different key for storage in a destination buffer associated with the destination virtual machine. In some examples, the key identifier and source address is managed by the virtual channel and is not visible to virtual machine or hypervisor.

Abstract: In the present disclosure, functions associated with the central office of an evolved packet core network are co-located onto a computer platform or sub-components through virtualized function instances. This reduces and/or eliminates the physical interfaces between equipment and permits functional operation of the evolved packet core to occur at a network edge.

Abstract: A computer-implemented method can include receiving a queue depth for a receive queue of a network interface controller (NIC), determining whether a power state of a central processing unit (CPU) core mapped to the receive queue should be adjusted based on the queue depth, and adjusting the power state of the CPU core responsive to a determination that the power state of the CPU core should be adjusted.

Abstract: Technologies for dynamically managing a batch size of packets include a network device. The network device is to receive, into a queue, packets from a remote node to be processed by the network device, determine a throughput provided by the network device while the packets are processed, determine whether the determined throughput satisfies a predefined condition, and adjust a batch size of packets in response to a determination that the determined throughput satisfies a predefined condition. The batch size is indicative of a threshold number of queued packets required to be present in the queue before the queued packets in the queue can be processed by the network device.

Abstract: Technologies for providing information to a user while traveling include a mobile computing device to determine network condition information associated with a route segment. The route segment may be one of a number of route segments defining at least one route from a starting location to a destination. The mobile computing device may determine a route from the starting location to the destination based on the network condition information. The mobile computing device may upload the network condition information to a crowdsourcing server. A mobile computing device may predict a future location of the device based on device context, determine a safety level for the predicted location, and notify the user if the safety level is below a threshold safety level. The device context may include location, time of day, and other data. The safety level may be determined based on predefined crime data. Other embodiments are described 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.
