Method and apparatus for implementing a sleep proxy for services on a network
First Claim
1. A method for implementing a sleep proxy, comprising:
- receiving a registration request from a device, wherein the registration request contains;
sufficient information to allow the sleep proxy to generate a wakeup packet that can wake up the device,a list of requests for which the sleep proxy can answer, anda lease expiration time, wherein upon reaching the lease expiration time, the sleep proxy cancels the device registration; and
adding the device to the list of devices for which the sleep proxy answers;
receiving a request at the sleep proxy for information pertaining to a service provided by the device;
determining if the device is a device for which the sleep proxy answers;
if so, determining if the request is a request for which the sleep proxy can answer; and
if so, sending a response to the request on behalf of the device.

Abstract
One embodiment of the present invention provides a system for implementing a sleep proxy. The system starts by receiving a request at the sleep proxy for information pertaining to a service provided by a device. In response to this request, the system determines if the device is a member of a list of devices for which the sleep proxy takes action. If so, the system determines if the sleep proxy can answer the request. If so, the sleep proxy sends a response to the request on behalf of the device. In a variation on this embodiment, if the system cannot answer the request on behalf of the device, the system sends a wakeup packet to the device, wherein the wakeup packet causes the device to exit a power-saving mode so that the device can respond to the request directly.

15. An apparatus that implements a sleep proxy, comprising:
-
a registration mechanism configured to receive a registration request from a device, wherein the registration request contains; sufficient information to allow the sleep proxy to generate a wakeup packet that can wake up the device, a list of requests for which the sleep proxy can answer, and a lease expiration time; a list addition mechanism configured to add the device to the list of devices for which the sleep proxy answers; a cancellation mechanism that is configured to cancel the device registration upon reaching the lease expiration time; a receiving mechanism configured to receive a request at the sleep proxy for information pertaining to a service provided by the device; a determination mechanism configured to determine if the device is a device for which the sleep proxy answers; a second determination mechanism configured to determine if the request is a request for which the sleep proxy can answer if the device is a member of the list of devices for which the sleep proxy answers; and a response mechanism configured to send a response to the request on behalf of the device if the request is a request for which the sleep proxy can answer. - View Dependent Claims (16, 17, 18, 19, 20, 21)
