Abstract
In a computer network including a plurality of interconnected computers, one of the computers being a sleeping computer in a power down state, the sleeping computer listening for a packet associated with the sleeping computer, a method of waking the sleeping computer from the computer network. An incoming packet of data is transmitted from an administration system in the network to the sleeping computer. When the sleeping computer detects the incoming packet, it determines if the incoming packet contains a data sequence associated with the sleeping computer. If the incoming packet matches the particular data sequence associated with the sleeping computer, the sleeping computer transmits a reply message to the administration system. Upon receiving the reply, the administration system modifies the reply message in a predetermined manner and transmits the modified reply to the sleeping computer. If the sleeping computer determines the reply message was modified in the predetermined manner, then a signal is issued to wake the sleeping computer. Otherwise, the incoming packet is discarded and the sleeping computer is not awakened.
