Power management system to select a power state for a network computer system based on load
First Claim
Patent Images
1. A computer system comprising:
- a network interface coupled with a network to receive an increased network load comprising load portions for each of an increased plurality of connections with electronic network access devices;
a power state selection system coupled with the network interface to receive at least a representation of the increased network load, to select a higher power state that consumes more power by comparing the representation with a predetermined threshold to determine that the representation is greater than the threshold, and to assert a power state selection signal that corresponds to the higher power state;
a power state implementation system coupled with the power state selection system to receive the asserted power state selection signal and to assert a corresponding power state implementation signal;
a processor coupled with the power state implementation system to receive the power state implementation signal, to switch to the higher power state, and to execute operations associated with the receive network load at the higher power state; and
a power source coupled with the computer system to supply an increased amount of power to the computer system to power the processor in the higher power state.
