Abstract
Techniques for collaborative power management for heterogeneous networks are described. An apparatus may include a first node having a managed power system and a power management module to manage power states for the managed power system. The power management module may be operative to communicate power state information with a second node over a communications connection, and manage the power states for the managed power system based on power state information for the second node. Other embodiments are described and claimed.
Claims23
An apparatus, comprising:
- a first node having a managed power system and a power management module to manage power states for the managed power system, the power management module operative to communicate power state information with a second node over a communications connection, and manage the power states for the managed power system based on power state information for the second node, the managed power system to include a communications sub-system and a computing sub-system, the power management module having a power management controller operative to control varying levels of power provided to the communications sub-system and the computing sub-system based on an idle duration parameter and a resume latency parameter of the power state information for the second node, the power management module to modify a power level for the communications sub-system or the computing sub-system from a first power level to a second power level based on the idle duration parameter and resume latency parameter for the second node.
A system, comprising:
- a first node having a managed power system and a power management module, the managed power system comprising a digital electronic display, a communications sub-system and a computing sub-system, the power management module operative to communicate power state information with a second node over a communications connection, and manage power states for the communications sub-system or the computing sub-system based on power state information for the second node, the managed power system to include a communications sub-system and a computing sub-system, the power management module having a power management controller operative to control varying levels of power provided to the communications sub-system and the computing sub-system based on an idle duration parameter and a resume latency parameter of the power state information for the second node, the power management module to modify a power level for the communications sub-system or the computing sub-system from a first power level to a second power level based on the idle duration parameter and resume latency parameter for the second node.
A method, comprising:
- communicating power state information between a first node and a second node over a communications connection;
- determining a power state and a power state duration period based on the power state information for the second node;
- switching a managed power system of the first node to the determined power state for the power state duration period, the managed power system to include a communications sub-system and a computing sub-system;
- controlling varying levels of power provided to the communications sub-system and the computing sub-system based on an idle duration parameter and a resume latency parameter of the power state information for the second network device;
- and
- modifying a power level for the communications sub-system or the computing sub-system from a first power level to a second power level based on the idle duration parameter and resume latency parameter for the second network device.
