Abstract: Device discovery on a local network can cause suspended devices to not respond or to wake up and respond, both of which may be undesirable. To enable suspended devices to respond to a device discovery request without waking up, network interface controllers (NIC) are programmed with a device discovery protocol. A first device broadcasts a discovery frame that includes information indicating that it is a discovery frame. The NIC of a second device determines whether the received frame is a discovery frame. In response to receiving a discovery frame, the NIC of the second device returns a response that includes its device identifier. The NIC may issue the response frame directly, without waking up the second device. Alternatively, the NIC causes the second device to enter a discovery state, which enables the second device to respond to a discovery packet and then return to a suspend mode.
