Abstract
A computing device that has a network interface that performs a subset of possible networking functions while the computing device is in a sleep mode. The subset of functions may be simply implemented on the network interface, yet to substantially reduce the frequency with which the computing device has to wake up to perform networking functions. The subset of functions may be selected to maintain a network presence of the computing device while the device is in sleep mode, and may include responding to requests for MAC information, sending keep-alive messages or exchanging security information that, in accordance with network protocols, has a limited lifetime that would otherwise expire while the computing device is in sleep mode.
