Abstract:
1. A method, comprising: filtering, by a filtering module of a network interface controller device configured to provide an interface between a network and a host interface, a network packet received from the network and comprising a graceful power control command, wherein the network packet is intercepted by the filtering module; interpreting, by the network interface controller device, the network packet to obtain the graceful power control command; storing, by the network interface controller device, the graceful power control command into a shared memory located in the network interface controller device; notifying, by the network interface controller device in an arrival notification, a power management agent service of arrival of the graceful power control command in the shared memory; and providing, by the network interface controller device, the graceful power control command from the shared memory to the power management agent service via the host interface in response to receipt of the arrival notification by the power management agent service, wherein an operating system function corresponding to the graceful power control command is invoked by the power management agent service.
