1. A method for optimizing power consumption in a communication system comprising a network interface and a host computer, the method comprising:
- determining, by the network interface, at least one power mode of the host computer from a plurality of possible power modes; and
selecting, by the network interface, at least one network interface power management state from a plurality of possible power management states based on the at least one power mode determined, wherein selecting further comprises;
configuring a PHY layer to restart and negotiate at a predetermined speed; and
increment advertized capabilities until link presence is detected; and
wherein the network interface is operably coupled to the host computer and provides access for the host computer to the network, and wherein the network interface;
locally detects a non-zero volume of traffic received by said network interface; and
locally selects the power management state for the network interface from the plurality of possible power management states based at least in part on the volume of non-zero traffic received by said network interface.
