Telecommunications Management Network
BY STÅLE WOLLAND
Introduction
Telecommunications Management Network (TMN) is an architectural
concept for communication and processing of management
information for tele- and data communications networks.
The objective is to be able to implement management capability
over a distributed management network (logically and/ or physically)
in a standardised way so as to be system and vendor independent.
Interoperability and re-use of management resources
are also important objectives.
This summary presents some of the work going on in ISO/IEC.
Future presentations will address some of the other work going
on in ITU-T, ETSI, Network Management Forum and RACE.
There is also management work going on in ANSI, ECMA,
IEEE, TINA-C and other bodies.
ISO/JTC
The standardisation of Open Systems Interconnection (OSI)
Management is performed within JTC1/WG21/WG4. The work
was originally directed at management of Open System Interconnection
resources.
The applicability of the work to areas such as telecommunications
services has long been recognised and there is now harmonisation
and co-ordination between the two areas ISO/IEC
OSI Management and ETSI / ITU-T TMN. This harmonisation
is the responsibility of ITU-T SG VII.
There are now International Standards in 17 management areas
(in addition to the ISO/IEC designation the corresponding ITU-
T Recommendation is also indicated):

There is work going on in a large number of other areas. The
state of progress varies from Working Draft (WD) through
Committee Draft (CD) to Draft International Standard (DIS).
Areas of ongoing work include the following:
