Abstract
An apparatus and method for remote wake-up of an intended node within a data exchange system having interlinked networks (e.g., router-interlinked LAN's) is disclosed. A wake-up commanding format is disclosed wherein a sequence corresponding to the address of the intended node is embedded N consecutive times (e.g., at least 16 consecutive times) extensively through the respective data fields of one or more packets sent from a remote source node to the intended node. When this particular sequence is received by the intended node while the intended node is in a sleep mode, a wake-up operation is responsively initiated so that the sleeping node will awaken, at least for a time, to respond to future received packets.
