AIPW Summary: Existing networkable devices often have a power saving mode (e.g., a sleep mode). To wake a device from a sleep mode, a special “wake up” packet is sent. However, without the wake up packet, a sleeping device would not be able to respond to requests made of the device. A sleep proxy is activated for the device and responds to requests made of the sleeping device, if the proxy is able to handle the request. If the proxy is not able to handle the request, then the proxy wakes the device to directly handle the request.
