Foreword
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 participate 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, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work.
The procedures used to develop this document and those intended for its further maintenance
are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria
needed for the different types of document should be noted. This document was drafted in
accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or
www.iec.ch/members_experts/refdocs).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents) or the IEC
list of patent declarations received (see patents.iec.ch).
Any trade name used in this document is information given for the convenience of users and does not

Introduction
ISO/IEC TR 29181 is a series of standards on Future Network (FN). The subject of ISO/IEC TR 29181-9
is Networking of Everything (NoE).
1)
ISO/IEC 21558-3 specifies the architecture of the FN-NoE to provide further advanced NoE services
identified in ISO/IEC TR 29181-9.
This document focuses on the FN-NoE protocols and mechanisms, consisting of functional procedures,
service interfaces, and protocols, to provide the thing-user centric communication service upon the FN-
NoE architecture defined in ISO/IEC 21558-3.
1) Under preparation. Stage at the time of publication: ISO/IEC PRF 21558-3.
