IEC 62481-10:2017 pdf download.Digital living network ALLIANCE (DLNA) home networked device interoperability guidelines
1 Scope
This part of IEC 62481 specifies guidelines for low-power mode management. Power saving is modular within a physical device. In the context of DLNA networked devices, each physical network interface can have various power modes, some of which can allow Layer 2 or Layer 3 connectivity to still be present, even when many of the other components of the device are powered down. Other physical components, such as screens, hard drives, and similar resources, can also support different power modes.

Any lowercase uses of these words have the normal technical English meanings.
4 Networking architecture and guideline conventions
4.1 DLNA home networking architecture This specification extends the DLNA home networking architecture that is defined in Clause 4 of IEC 62481 -1 -1 :201 7. 4.2 Document conventions See Clause 6 of IEC 62481 -1 -1 :201 7, for a description of the DLNA document structure and conventions. 4.3 Guideline structure and layout See 7.1 of IEC 62481 -1 -1 :201 7, for guideline and attribute table layout descriptions.
5 DLNA Device Model
5.1 General Refer to Clause 5 of IEC 62481 -1 -1 :201 7, for a description of the existing DLNA Device Model. This document extends the existing DLNA devices and system usages. 5.2 Device Functions Power saving is modular within a physical device. In the context of DLNA networked devices, each physical network interface can have various power modes, some of which can allow Layer 2 or Layer 3 connectivity to still be present, even when many of the other components of the device are powered down. Other physical components, such as screens, hard drives, and similar resources, can also support different power modes. – UPnP EnergyManagement Service: a UPnP EnergyManagement Service makes available information about the description and Network Interface Mode of a physical device’s network interface(s). It can also allow other devices to indicate when they are interested in ensuring the availability of the functionality in a DLNA Device Class, and to reserve use of the needed resources at that time. – UPnP EnergyManagement Control Point: a UPnP EnergyManagement Control Point issues action requests to a UPnP EnergyManagement Service to get information about the description and Network Interface Mode of a physical device’s Network Interfaces. It can also issue action requests to indicate when it is interested in ensuring the availability of functionality in a DLNA Device Class, and to reserve use of the needed resources at that time.
