Abstract
Techniques for communications based power management are described. An apparatus may comprise a managed power system having a communications sub-system and a computing sub-system, the communications sub-system to include a network state module operative to determine communications power state information, and send a power management message with the communications power state information. The apparatus may further comprise a power management module to receive the power management message, retrieve the communications power state information from the power management message, and manage power states for the computing sub-system based on the communications power state information. Other embodiments are described and claimed.
Claims25
An apparatus, comprising:
- a managed power system comprising:
- a communications sub-system;
- and a computing sub-system,
- the communications sub-system to include a media access controller and a PHY to provide a communications connection, a network state module operative to (a) determine communications power state information based on, at least in part, on at least one of (1) a status of the communications connection, or (2) at least one communication element of the communications sub-system and (b) send a power management message with the communications power state information;
- and
- a power management module to couple to the managed power system, the power management module to receive the power management message, retrieve the communications power state information from the power management message, and manage power states for the computing sub-system based on the communications power state information.
A method, comprising:
- receiving a power management message with communications power state information over a communications bus by a power management module from a communications sub-system of a managed power system, the communications sub-system having a media access controller and a PHY to provide a communications connection, the power management message based on at least one characteristic of the communications sub-system;
- determining a computing power state and a computing power state duration period for a computing sub-system of the managed power system based on the communications power state information;
- and
- switching the computing sub-system to the computing power state for the computing power state duration period.
An article comprising a non-transitory computer-readable medium containing instructions that if executed enable a system to:
- receive a power management message with communications power state information over a communications bus by a power management module from a communications sub-system of a managed power system, the communications sub-system having a media access controller and a PHY to provide a communications connection, the power management message based on at least one characteristic of the communications sub-system;
- determine a computing power state and a computing power state duration period for a computing sub-system of the managed power system based on the communications power state information;
- and
- switch the computing sub-system to the computing power state for the computing power state duration period.
