Abstract
A detector and method for detecting Wakeup-On-LAN (WOL) frames in which the Wakeup field can start on a two byte word boundary (even) or in the middle of the two byte word (odd). The orientation (even/odd) of the WOL and destination address (DA) fields are determined and a first or second two byte process, depending on the orientation, is selected to analyze the frame to determine if it is valid.
