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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC TR 62343-6-10, which is a technical report, has been prepared by subcommittee 86C:
Fibre optic systems and active devices, of IEC technical committee TC 86: Fibre optics.
The text of this technical report is based on the following documents:

Full information on the voting for the approval of this technical report 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 IEC 62343 series, published under the general title Dynamic modules,
can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

INTRODUCTION
Software defined networking (SDN) technology is widely recognized as a promising solution
for flexible and efficient provisioning of networks by virtualizing their infrastructures, which
results in cost-effective realization of high capacity, low energy consumption and even low
latency. SDN technology will remain highly influential over global industries, societies, and the
environment for many years to come.
Optical fibre communication technology has offered sufficient transport capacity with a fixed
physical topology. However, recent technological progress in optical networking enables
physical reconfiguration of optical paths by controlling multiple dynamic modules such as
wavelength division multiplexing (WDM) devices and switching devices. Here, the key is to
have an intermediate controller that controls and maintains the multiple dynamic modules in
an integrated fashion, according to the upper layer controller of the SDN.
In order to realize such a reconfigurable and/or dynamically switchable optical network
infrastructures at a hardware level in a cost-effective, reliable, scalable and low-carbon
manner, it is important to initiate, in a timely manner and to a wide extent, conceptual and
technical discussions, particularly on the intermediate controller for future standardization.
It is very important for industries to identify requirements for network architecture and
devices/components in a timely manner, and to improve the technology development and
investment efficiencies.
The objective of this part of IEC 62343 is to contribute to the standardization of basic
requirements of the dynamic optical path networks using the intermediate controller.
