Abstract: Techniques for sampling and capturing central processing unit (CPU)-bound packets in a network device are provided. In one set of embodiments, the network device can receive a command to enable packet sampling for a class of network traffic, where the command specifies one or more sampling parameters. The network device can identify at least one CPU queue in a plurality of CPU queues of the network device to which the class of network traffic is mapped. The network device can then configure a driver of an operating system (OS) of the network device to begin sampling packets from said at least one CPU queue in accordance with the one or more sampling parameters.

Abstract: Embodiments of the present invention produce and define a relationship between local voltage and power measurements at a node of an electrical network and system conditions on a remote branch of the network. These local measurements are used to determine an optimal voltage set point at the node that, if realized by a reactive power resource, would affect the flow of reactive power or line current at one or more particular remote branches of the power system in a manner captured by the derived relationship. The change in reactive power required to obtain this voltage set point is also calculated based on local measurements.
