32、tions layers for network enhanced control devices of HES Class 1 FOREWORD 1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC part

33、icipate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, government

34、al and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. 2) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly as possible,

35、 an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees and ISO member bodies. 3) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted by IEC Nat

36、ional Committees and ISO member bodies in that sense. While all reasonable efforts are made to ensure that the technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4)

37、 In order to promote international uniformity, IEC National Committees and ISO member bodies undertake to apply IEC, ISO and ISO/IEC publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any ISO, IEC or ISO/IEC publication and t

38、he corresponding national or regional publication should be clearly indicated in the latter. 5) ISO and IEC do not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. ISO or IEC are not

39、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 ISO or its directors, employees, servants or agents including individual experts and members of their

40、 technical committees and IEC National Committees or ISO member bodies 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 of, use of, or reliance upon, this ISO

41、/IEC publication or any other IEC, ISO or ISO/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) Attention is drawn to the possibility that some of the

42、elements of this ISO/IEC publication may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. International Standard ISO/IEC 14543-4-3 was prepared by subcommittee 25: Interconnection of information technology equipment, of ISO/IEC

43、 joint technical committee 1: Information technology. The list of all currently available parts of the ISO/IEC 14543 series, under the general title Information technology Home electronic system (HES) architecture, can be found on the IEC web site and ISO web site. This International Standard has be

44、en approved by vote of the member bodies, and the voting results may be obtained from the address given on the second title page. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. IMPORTANT The colour inside logo on the cover page of this publication indicates that

BS ISO/IEC 14543-4-3:2015 6 ISO/IEC 14543-4-3:2015 ISO/IEC 2015 INTRODUCTION This part of ISO/IEC 14543 specifies the message struc

46、ture, sequences and protocol of the application layer for use in the Home Electronic System. Some services are targeted for communications between devices. Other services are exclusively reserved for management purposes. Some services can be used for both management and run-time communications. This

47、 standard is applicable for energy management services, mobile access, remote appliance maintenance services, home healthcare services, home security services and comfort control. This standard focuses on the application layers (5 thlayer to 7 thlayer of the OSI reference model). This standard speci

48、fies a message structure that differs from the 12 message structures specified in ISO/IEC 14543-4-1. This standard allows the use of IP addressing or MAC addressing, while ISO/IEC 14543-4-1 specifies a different non-IP address structure. This part depends on routing functions provided by an external

49、 IP layer. ISO/IEC 14543-4-1 uses the routing functions specified in ISO/IEC 14543-4-2. Therefore Part 4-3 is an alternative to Part 3-1 plus Part 3-2. ISO/IEC 14543, Information technology Home Electronic System (HES) architecture, provides an introduction to specifications for Home Electronic System (HES): Part 2-1: Introduction and device modularity and specifications for three types of HES devices: Parts 3-x Specifications for network based contro
