16、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 t
17、o 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
18、 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 condi
19、tions 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 Nati
20、onal 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 wa
21、y 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
22、 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. I
23、EC 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 it
24、s 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 oth
25、er 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 elements of this IEC Publication may be the
26、 subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance with this Technical Specification may involve the use of a maintenance servic
27、e concerning the stack of protocols on which the present specification IEC 62056-8-20 is based. The IEC takes no position concerning the evidence, validity and scope of this maintenance service. The provider of the maintenance service has assured the IEC that he is willing to provide services under
28、reasonable and non-discriminatory terms and conditions for applicants throughout the world. In this respect, the statement of the provider of the maintenance service is registered with the IEC.

29、2056-8-20:2016 IEC 2016 5 The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International
30、 Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to
31、decide whether they can be transformed into International Standards. IEC TS 62056-8-20, which is a technical specification, has been prepared by technical committee 13: Electrical energy measurement and control. The text of this technical specification is based on the following documents: Enquiry dr
32、aft Report on voting 13/1673/DTS 13/1704/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the
33、 IEC 62056 series, published under the general title Electricity metering data exchange The DLMS/COSEM suite, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webs
34、tore.iec.ch“ in the data related to the specific publication. At this date, the publication will be transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The colo

36、ODUCTION As defined in IEC 62056-1-0, the IEC 62056 DLMS/COSEM suite provides specific communication profile standards for communication media relevant for smart metering. Such communication profile standards specify how the COSEM data model and the DLMS/COSEM application layer can be used on the lo
37、wer communication media-specific protocol layers. Communication profile standards refer to communication standards that are part of the IEC 62056 DLMS/COSEM suite or to any other open communication standard. This Technical Specification specifies a DLMS/COSEM IPv6 based communication profile that ca
38、n be used in large scale AMI deployments where the Neighbourhood Networks are mesh networks. The communication profile specified in this Technical Specification can be used over various suitable technologies providing a Neighbourhood Network with mesh topology, as long as they are capable to carry I
39、Pv6 traffic. This specification follows the rules defined in IEC 62056-5-3:2016, Annex A. The communication profile specified in this specification addresses the specificities resulting from the properties of the mesh network and the large quantity of devices to be managed.

40、IEC TS 62056-8-20:2016 IEC 2016 7 ELECTRICITY METERING DATA EXCHANGE THE DLMS/COSEM SUITE Part 8-20: Mesh communication profile for neighbourhood networks 1 Scope This part of IEC 62056 specifies a DLMS/COSEM communication profile that can be used in a smart metering system in which the Neighbourhoo
41、d Networks (NN) are mesh networks. This profile may be considered as an adaptation and extension of the UDP/IP communication profile specified in IEC 62056-9-7:2013. As in that standard, the PHY and MAC layers are out of the Scope. This Technical Specification specifies a number of features essentia
42、l to the efficient operation of a large scale AMI using mesh NNs. These features include: identification of the DLMS/COSEM client and server participating in an application association (AA) with their system title, so that this identification does not change when the IP address of the server changes
43、, see Clause 6; a mechanism to inform the client of the binding between the servers system title and its current IP address(es), see 5.5.3; the use of the DLMS/COSEM UDP based transport layer, that allows keeping DLMS/COSEM AAs open for long periods, while the device may leave and join the mesh NN a
44、nd/or its IP address may change, see 7.2.2; DLMS/COSEM application layer and application process level security features that can be used in a mesh environment, see 7.4.2; a mechanism to organize servers to one or more groups based on various conditions, so that the requests can be broadcasted to al
45、l devices attached to the mesh network, but only those servers belonging to the group carry out the request and respond, see 8.2; a mechanism that allows to send the response to a request in designated time windows and with a randomized delay, see 8.3. the use of a specific UDP port that allows effi
46、cient UDP header compression, see 6.3.3. The Scope of this communication profile specification is restricted to aspects concerning the use of communication protocols in conjunction with the COSEM data model and the DLMS/COSEM application layer. Any project specific definitions of data structures and
47、 data contents may be provided in project specific companion specifications. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
