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 https://patents.iec.ch ).

Introduction

This document and ISO/IEC 21559-2 both pertain to the Future Network (FN).

This document analyses and specifies how to define the Future Network Quality of Service (FNQoS) based on AI-proxy, and how to express the architecture of FNQoS information system based on FNProxy. The goal of the FNQoS is directly related to ISO/IEC TR 29181-8.

FNQoS architecture not only defines the FNProxy contents of FNQoS, but also describes the necessary functional support required for the operation of FNQoS system. Further, FNQoS architecture itself is the basis for the normal operation of the protocol mechanism supporting FNProxy interaction specified in ISO/IEC 21559-2.

The function of Bidirectional Service (Bi-S) for interaction among FNProxies is the basic element of the FNQoS system. This document is based on the basic elements of Bi-S using ISO/IEC 19501 and ISO/IEC/IEEE 42010 to analyse and stipulate the reusable pervasive reference architecture technology of FNQoS.

The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) draw attention to the fact that it is claimed that compliance with this document may involve the use of a patent.

ISO and IEC take no position concerning the evidence, validity and scope of this patent right.

The holder of this patent right has assured ISO and IEC that he/she is willing to negotiate licenses under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with ISO and IEC. Information may be obtained from the patent database available at www.iso.org/patents or https://patents.iec.ch .

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights other than those in the patent database. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

1 Scope

This document describes the architectural aspects of Future Network (FN) Quality of Service (QoS) based on an FNProxy model, taking into account the requirements described on ISO/IEC TR 29181-8. It describes:
