Telecommunications
Management Network: From Concept to Reality
a market research report
|
|
The boundaries separating the various segments of mass
communications industries have collapsed, and the
digitization of daily life is putting new requirements on
network providers. A digital network infrastructure is
nothing new, but its density is imposing drastic new
requirements on telecommunications management
technologies.
Accompanying the growth in the volume of things to be
managed is an explosion in the complexity of things to be
managed. Networks are shifting from lower speed,
dedicated rate, and inflexible services to fully
configurable, bandwidth on demand, mobile, and high-speed
services––and management systems must adapt.
The end goals of the TMN standard are to:
-
Maximize investment in network resources;
-
Deliver reliable, predictable service;
-
Provide functions to detect, isolate, and recover from
failures;
-
Assign network resources to services; and
-
Assist in the design and planning of new network
resources.
The Telecommunications Management Network
(TMN)
Recommendation, as defined by the ITU, refers to the
network management of telecommunications networks.
Insight’s research suggests that integrating TMN-compliant network managment systems into the
carriers’ networks will be crucial to their
well-being and profitability––and to the public
they serve.
Telecommunications Management Network is organized to
provide you with a complete overview of the marketplace,
including applicable standards and methodologies, market
forecasts, and detailed descriptions of the key vendors.
This report will help network management system vendors
and users alike to determine how best to incorporate
telecommunications network management technology into
their plans, products, and procurements.

Telecom Network Overview
For the past thirty years, telecommunications network
providers around the
world have been gradually adding digital transmission and
switching capabilities to their analog networks. In the
past ten years, however, a tidal wave of digital devices
including music CDs, pocket pagers, and home computers
have swept into everyday use. At the same time, the
boundaries separating the various segments of mass
communications industries have collapsed and new terms
like convergence and multimedia have arisen to describe
the phenomena. This digitization of daily life is putting
new requirements on network providers. A digital network
infrastructure is nothing new--but its density is
imposing drastic new requirements on telecommunications
management technologies, especially those that combine
surveillance and control for many different types of
elements.
Network management describes the activities associated
with improving network traffic flow and customer service
when abnormal conditions such as equipment failures or
unusual traffic patterns have resulted in a congested and
inefficient network. Network management is responsible
for supervising the performance of the network and, when
necessary, controlling the flow of traffic to obtain the
maximum use of network capacity.
When a private data communications network approaches the
size and complexity of a telecommunications network and
contains many of the same network elements (i.e., fiber
optic systems, digital cross connects, etc.), their
network management requirements often overlap. However,
the telecommunications network operations environment
poses unique requirements that differ from the priorities
of private data networks or distributed computer systems
management. Trying to apply the same management
technology used for private nets or distributed computing
environments to telecommunications may have disastrous
consequences.
Management interfaces in the private data environment,
for instance, have moved to near-universal support for the Simple Network
Management Protocol (SNMP). SNMP managers generally share
some common attributes:
- Generic topology management;
- Integration through a simple Graphical User Interface
(GUI); and
- Single user-oriented design.
In the public environment, however, a more heterogeneous
mix of RS-232 console interfaces, bit-oriented telemetry
protocols, and de facto industry standards such as
Transaction Language 1 (TL1) have prevailed, with a move
toward Common Management Information Protocol (CMIP)
support. Integration requirements are more complex,
involving the real-time coordination of state information
across multiple applications. Scalability is a major
consideration, and a multi-threaded, object-oriented
approach to development is considered a must.
It is in this context that the Open Systems Interconnect (OSI) management
schema defined by the ITU is gaining wide acceptance. The
ITU's CMIP defines a much larger set of protocols than
SNMP and provides mechanisms for distribution of the
messaging load between all the parts of the network being
managed.
The OSI standards for network management are defined as
five distinct disciplines:
- Fault Management;
- Performance Management;
- Configuration Management;
- Security Management; and
- Accounting Management.
The Telecommunications Management Network (TMN)
Recommendation, as defined by the CCITT M.3010, refers to
the network management of telecommunication networks. The
OSI protocols are used for the implementation of the
communications in the TMN standard.
The end goal of the TMN standard is to:
- Maximize investment in network resources;
- Deliver reliable, predictable service;
- Provide functions to detect, isolate, and recover from
failures;
- Assign network resources to services; and
- Assist in the design and planning of new network
resources.
Given the increasing complexity of the telecommunications
networks and the growing demands being placed on them by
the digitization of daily life,
Insight's research suggest integrating TMN-compliant
network management systems into the carriers' networks
will be crucial to their well being and prosperity--and
the public they serve.
Market Drivers
Until the early 1980s, the only remotely manageable
elements in a telephone network were switches--on
average, one element per 8000 subscriber lines. With the
advent of software controlled transmission, millions more
elements are manageable--about one per 500 subscriber
lines. In a second generation digital loop carrier
environment, a digital cellular environment, or in a
hybrid fiber/coax system, at least one element per
subscriber--and eventually many elements per
subscriber--must be managed.
As a result, the sizes of configuration databases and
event message flows are growing exponentially. In addition, the
interdependence of elements and difficulty in isolating failures grows with them.
This leads to a high value being placed on a management system's long term
scalability, its ability to manage the filtering and
reduction of messages, and its robustness when subjected
to extremes of load.
This growth in the volume of things to be managed is
accompanied by an explosion in the complexity of things
to be managed. High growth segments of the
telecommunications equipment market--SONET/SDH, ATM,
digital wireless--are also highly complex in terms of the
configuration and criticality. As networks shift from
lower speed, dedicated rate, and inflexible services to
fully configurable, bandwidth on demand, mobile, and high
speed services, management systems must adapt.
Moreover, telephone companies are under considerable
pressure to maintain or increase profitability, so
overhead within the company must be kept to a minimum. A
major contribution to this overhead are the human
resources required to effectively manage and provision
the network.
Network operations systems ease the introduction of new
services, but they
also must contribute to better use of capital (more
efficient use of transmission and switching resources)
and more productive use of people. Investment in OSSes
has enabled only a fourfold increase in productivity in
over thirty years. Further progress will result not from
further automation of existing work centers, but from
re-engineering work processes to take advantage of
management technology.
