Overview

IEC 62608-1:2025 - Multimedia home network configuration - Basic reference model - Part 1: System model defines a system-level reference for automatic configuration of IP devices in home networks. This second edition updates the 2014 version by adding wireless LAN devices and cloud servers, and specifies the roles, functions and interactions required to configure devices that are cable or wireless LAN connected, switched on, and supporting IP. The reference model covers both inside (local) and outside (cloud/external) network connectivity and describes the system components and their expected behavior.

Key topics

• Configurator and Configuration Agent: Definitions and responsibilities of the configurator (management entity running in the home network) and the configuration agent (software on managed devices) - core to the multimedia home network configuration model.
• System model and management model: Component roles, layered management, and the functions each element should support to enable automated setup and operation.
• Network configuration framework: Coverage of the configuration protocol, configuration data model and associated metadata required for reliable device onboarding and management.
• Inside and outside connectivity: How the model accounts for local LAN (including wireless LAN) and external service servers or cloud-hosted functionality.
• Use cases and examples: Informative annexes include audio/video equipment configuration and sensor management scenarios illustrating real-world workflows.

Practical applications

IEC 62608-1:2025 is intended for practitioners involved in designing, building and operating IP-based home networks and services:

INTRODUCTION
Electronic power, as well as network connectivity, is necessary in order to use electronic
devices at home. Some applications running on the devices do not work without an inside and
outside network.
When a device connects to a home network, an appropriate network service needs to must
already be in place. Since network connections are a precondition of many applications, such
as the applications in IEC 62481-1, IEC 62481-2 and IEC 6248-3, a digital living network
alliance (DLNA) network management function is necessary.
Sometimes applications need are asked to change the configuration of another device, gateway,
and so on. Since it is too difficult to change the configuration of the device manually, an
automatic configuration mechanism is needed for the home network. IEC 62514 defines the
functions of a multimedia home gateway; this document complements the multimedia home
gateway by enabling to establish establishing network connection automatically.
This document expands the scope of management to include devices connected via wireless
LAN and servers on the cloud.

4 Model
4.1 General
This document defines the configurator that manages the configuration information of
equipment connected to a home network and the configuration agents that are managed by the
configurator.
4.2 Configurator
The configurator configures the equipment as needed and runs on a home network.
The configurator assumes that all devices are set up on the layer 2 network, i.e. and that all
devices are cable connected with pieces of network equipment. Based on the environment, the
configurator supports the creation of a layer 3 connection and application running on consumer
equipment.
4.3 ConfiguredConfiguration agent
The configured configuration agent sends configuration information to the configurator and
configures equipment requested by the configurator. The configured configuration agent runs
on the equipment managed by configurator.
The configured configuration agent specifies the procedure needed to establish the of
connection establishment with the configurator on the layer 2 network. Once the connection is
established, the configured configuration agent operates as required by the configurator. The
function of the configured configuration agent consists of collecting information from the devices,
changing the device configuration, and so on.
4.4 System model
Figure 1 shows the system model of the configurator and configured configuration agent. The
lines connecting the configurator and AV equipment, etc., indicate that they are on the
broadcast domain. This applies to both wired and wireless connections.

4.6 Management model managed by the configurator
The information that the configurator collects can be divided into the categories of L1/L2
Network, L3 Network, and Service:
a) L1/L2 Network manages the physical connections and L2 connections within the home
network;
b) L3 Network manages the L3 network configuration between the home network and the cloud,
etc.;
a) Service manages the devices and applications that connect to the network and are visible
to the user.
The configurator manages all this information in a coordinated manner and makes it accessible
as needed (see Figure 3 for layered management model).
