FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent

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.
1 Scope
This part of IEC 62608 specifies the basic reference model to configure devices connected to
a home network with a configuration framework for network applications running on such
devices.
This document applies to devices that are cable or wireless LAN connected via cables and
switched on and that support IP protocol. The reference model covers inside and outside
network connectivity.
This document specifies the system model and functions that each component should support.

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.

4.5 Configuration model
The configurator obtains the configuration information from the configured configuration agent
running on each item of equipment and requests it to configure as needed. The configurator
also requests configurations to the home gateway. Figure 2 shows how the configurator obtains
information and the configuration request model.

For the use cases, see Annex A for audio and video settings in home and in studio, and Annex B
for management sensor devices in the home network.
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).
