ABSTRACT:
A device connected to a network operates in a plurality of states including an execution state and a low-power state. During operation in the low-power state, the device is activated to an execution state in response to standard messages such as Ethernet messages. A receiving device connected to a network is activated from a suspended or low-power state by the receipt of a message from a sending device. The message necessarily includes a unique Ethernet address identifying the destination device in accordance with a standard specification, such as the IEEE 802.3 specification. The receiving device reads the unique Ethernet address of the message, determines a type classification of the message content, and determines whether to become activate or remain in the low-power state on the basis of the Ethernet address and the message type.
