A 3-days Course in OSI Management and TMN
The UHC Course in OSI Management and TMN has been several times
in Copenhagen and has received considerable acknowledgements and
recommendations.
The standard arrangement covers 2 full days and a half day and
includes 3 lunches, beverages and lecture notes.
(Consult the UHC News Page for the
date of the next arrangement.)

Resume
The course provides you with a thorough understanding of the concepts
and architecture and technologies of Telecommunications Management
Network TMN as defined in ITU M.3010.
The Telecommunications Management Networks principles and architecture
as defined in M.3010 are explained, highlighting its hierarchical
logical layered aspects. The TMN interfaces and the methodology
for standardising those are presented.
The Object-oriented concepts and the formal specification of managed
objects in GDMO and ASN.1 will be explained. The facilities of the
OSI management service/protocol (CMIS/CMIP) are examined as well
as the most important Systems Management Functions, which constitute
generic functionality available at management interfaces.
The most prevalent Network management technologies, like SNMP,
CORBA and Web management are shortly presented and compared with
CMIS/CMIP.
Sample commercial offerings are discussed.
Benefits of attending the Course
The object of this course is to give the participant:
- a better understanding of the scope and mission of TMN and TMN's
technological and commercial potential,
- an overview of the concepts and terminologies used in TMN,
- an overview of the existing TMN standards,
- a better foundation to compare various competing management
technologies,
- a major kick-start to get started with TMN.
The typical participant is a product or project manager, which
needs to get an overview of the TMN technology in a start-up phase.
Also developers, which are about to enter a TMN development project
will benefit by attending the TMN course in the early phases of
the project (e.g. as a precondition to the Q3ADE Starter course).
Preconditions
The participant should have basic knowledge about Network or System
Management.
A basic knowledge about computer networking and computer languages
will be an advantage.

The Perspective of Telecommunications
Management
This tutorial presents TMN as the cure to the future demands on
integrated systems management that is dictated by the evolution
of the Telecom Service Market.
It is also the purpose of this tutorial is to convince the audience
about the grander potential of TMN and its applicability within
and beyond the telecommunications sector.
TMN: Telecommunication Management Network. Framework/Principles
The course begins with an overview of the M.3010 recommendation
that defines the TMN architectural framework, covering the functional,
information and physical aspects of the architecture and the notion
of reference points and interfaces. The logical layered concepts
are introduced and explained. Extensions of the architecture to
encompass the use of directory services for distribution and shared
management knowledge are presented.
CMIS/CMIP: Common Management Information Service/Protocol
A detailed examination of the facilities CMIS provides to access
managed objects, the implementation of CMIP over ROSE and the negotiations
for association establishment through ACSE.
SMI: Structure of Management Information
OSI management follows a fully object-oriented specification methodology.
The basic principles of object-oriented modelling and design are
explained. OSI management introduces the notion of managed objects
which can be manipulated through operations, emit notifications
and exhibit behaviour at the object boundary.
GDMO: Guidelines for the Definition of Managed
Objects
GDMO specifies the relationships between the relevant OSI management
Recommendations and International Standards and the definition of
managed object classes and the appropriate methods to be adopted
for the definition of managed object classes and their attributes,
notifications, actions and behaviour.
The purpose of this tutorial is to provide an overview of the GDMO
language elements.
ASN1/BER: Abstract Data Representation
A short introduction to the OSI Abstract Syntax Notation One (ASN.1)
language and the Basic Encoding Rules (BER) which are used to describe
both the management protocol (CMIP) and the values of messages to
managed objects.
X.731: State Management Function
The Recommendation X.731 defines the generic attributes and operations
that can be part of any managed object definition in order to provide
a standardized OSI management technique for dealing with management
states.
X.733: Alarm Reporting Function
The alarm notifications defined by X.733 provides information that
a manager may need to act upon pertaining to a system's operational
failiure and quality of service failures. Standardised values are
defined for alarm types, severity level and probable Causes that
may be applied to a wide range of fault cases.
X.734: Event Report Management Function
The event report management model of X.734 describes the conceptual
components that provide for remote event reporting and local processing
of potential event reports. The model also describes the control
messages, event reporting messages and retrieval messages.
The tutorial walks though the functionality of the EFD (Event Forwarding
Discriminator).
X.735: Log Control Function
Conceptually, the Log defined in X.735 store incoming event reports
and local system notifications. However, logs can be used to store
information that is derived from notifications in the local open
system, incoming event reports and PDUs received or transmitted
by the open system. These three sources of information are modelled
in two basic ways, so that conceptually the log only deals with
event reports and local system notifications.
X.739: Metric Objects and Attributes
A X.739 Scanner object (or siblings) may be attached to any numeric
attribute in any object instance
in a Q3ADE based agent. Depending on the object class capabilities
and the actual configuration
of the monitoring object instance it will then be able to monitor
the value of the attribute periodically
and submit Quality Of Service Alarms in case it passes beyond a
configured threshold value.
Or it may perform a smoothing algorithm to obtain an estimate of
the average value
Technology specific TMN standards
A vast number of technology specific management information standards
are developed by ITU, ETSI, ANSI, SIF and others. This tutorial
presents these standards and their role and interrelationships.
A very large library of standards exist for specific Telecom technologies
like ATM, SDH, Sonet and PDH, developed by organisations like ITU,
ETSI, Sonet Forum, ATM Forum and Telemanagement Forum. An overview
is given together with an overview of these organisations.
SNMP: Simple Network Management Protocol
This tutorial is a short walk-through of SNMP, presenting the basic
concepts of SNMP and the latest additions in version 3.
CORBA: Common Object Request Broker Architecture
This tutorial is a short walk-through of CORBA, presenting the
basic concepts and the latest development
Comparing TMN with SNMP, CORBA, and Web
management
The OSI Management technologies are competing with several other
management technologies, like SNMP, CORBA and Web Management. You
will frequently be confronted with oversimplified views on which
is better.
These technologies are therefore presented shortly and a taxonomy
is given to help you make your own decision on which is better for
a given purpose.
Commercial Offerings
An overview of commercial offerings, mainly in the form of OSI-based
platforms (toolkits and relevant infrastructure) supporting the
development of TMN applications.
