Abstract:
1. In a receiving computer system that is communicatively coupled to an IEEE 1394 network, a method for waking a link layer at the receiving computer system based on data included in a network data packet, the method comprising: an act of a physical layer receiving a network data packet from a sending computer system, the sending computer system being communicatively coupled to the IEEE 1394 network; an act of the physical layer parsing a plurality of bytes of packet data contained in the received network data packet; an act of comparing at least a portion of the packet data to rule data in a physical layer rule register; an act of determining whether a corresponding link layer is in a reduced power mode; and an act of determining if the physical layer is to assert a Link On signal based on the results of the comparison and upon determining that the corresponding link layer is in the reduced power mode, the Link On signal being a signal that, when received at the link layer, wakes the corresponding link layer.
