Introduction

The UPnP Low Power architecture allows devices implementing power saving modes to conserve energy. The purpose of this document is to define an architecture that will address the issue of reporting and tracking power states of nodes in a network. The UPnP Low Power solution is designed to enable nodes in the network to report and track the Low Power states of other nodes in the network. Additionally, for nodes that support wake up capabilities, this architecture addresses methods to wake up those nodes when required. The objective of the UPnP Low Power solution is to allow UPnP devices to conserve energy and still be discoverable by UPnP Control Points. The UPnP Control Point will be aware of the UPnP devices and services implemented on a Low Power device even when the Low Power device is in a power savings mode.

This architecture document defines two UPnP services that comprise the UPnP Low Power framework:

• Low Power device service

• Basic Power Management Proxy service

The Low Power device service allows UPnP devices to transition to low power states and still be part of the UPnP network. The Basic Power Management Proxy service can optionally represent the sleeping UPnP devices in the network and is capable of certain limited functions to support the discovery of Low Power devices that are in a power saving mode. The introduction of Low Power into the UPnP architecture will help align UPnP with emerging energy regulation requirements.
