Abstract:
A network interface card, comprising:a multiplex control for controlling downloading of a wake-up pattern and a keep-alive packet from at least one of a plurality of sources into a first and second predefined locations, respectively, in a transmit packet buffer; a wake-up read control for controlling reading out of the wake-up pattern from the first predefined location; a keep-alive read control for controlling reading out of the keep-alive packet from the second predefined location; an arbiter for controlling the wake-up and keep-alive read controls, the arbiter capable of allowing the transmit packet buffer to transmit the wake-up pattern to a comparator substantially in parallel with transmitting the keep-alive packet to a network, the comparator capable of comparing the wake-up pattern from the transmit packet buffer with received packets from the network and generating a wake-up signal to a host when a match is found.
