Abstract
A method and apparatus for group power management of network devices. Some embodiments of an apparatus include a power management module, where the power management module is to transition the apparatus from a normal state to a low power state. The apparatus includes a wake module having a processor that remains active in the low power state, and a register to store a group address. The apparatus includes a network interface that is monitored by the processor in the low power state, where the processor detects a data packet identifying the group address at the network interface, and where the power management module returns the apparatus to the normal state upon detection of the data packet.
