The Changing Network Paradigm

Network as a scarce resource to unlimited bandwidth for all
 Pricing models changing from per minute to flat rate
 New network costing approaches

Overlay to Integrated
 Single network and equipment for voice and data as opposed
to different devices and networks

Circuit Switched to... IP over ATM to... IP
 More money will be spent on building data capacity and
devices than ever before, with lower spending on traditional
voice equipment

Wireless-based equipment will become the PRIMARY access over
time (Data and New Services)
 Wireless as just another access medium

The Rise of Wireless

“The future is a two-line world: one for fixed broadband, and one
for mobile wireless.”

“Fares for mobile services will keep going down, but usage will
increase”

“Eventually, people will only have one phone with a single
number. Within three to five years, mobile telephones will replace
local service

Minimization of complexity

Manageability of heterogeneous equipment

Provision of communication via standardized interfaces

Minimization of cost for management

Supporting Flexible configuration capability

Allowing remote control

Allowing interoperability between Network Operator/Service providers
for the exchange of management and charging information

Scalability for management of increasing network resources

Re-using of existing relevant standards

Assurance of system performance
KNOM2001 Tutorial

Management Technologies

Network management technology, e.g. OSI based TMN



Distributed object management technology, e.g. CORBA



Protocol management
Interoperability
Service definition, creation, deployment
Service interaction
GUI based customer management technology


Electronic customer access
Multi-modality
KNOM2001 Tutorial
Page 25
Need for Evolution of TMN

Telco business solutions are supported by a large range of
technologies with different levels of sophistication and maturity

The development will always face the following issues:



how to interact with existing legacy systems,
how to deal with multiple new technologies,
how to manage the overall lifecycle of the solution
development to reduce the chance of building legacy systems
KNOM2001 Tutorial
Page 26
Challenges to TMN Development

To use IT technology to enable the development and deployment
of its functions

To avoid turning BPR into a sequence of expensive R&D projects
and TMN development into a technology play

TMN development must have strong business focus and
disciplined management process

To provide an integrated TMN solution framework

To evolve and mature TMN as new technologies mature
KNOM2001 Tutorial
Page 27
TMN Is Not a Technology Framework

Defines the business objectives of the management solutions

Provides a reference framework for creating more functions and
management applications

Defines principles of management architecture and solutions

Provides partitions of management tasks into multiple domains
and multiple functional areas

Provides an abstraction view of management process models
and information models

Frameworks and Architecture

Define concepts and principles

Guide the overall solution architecture and the style of the
technology selection

No clear definitions of conformance to the overall architecture

No clear mandate for the technology
KNOM2001 Tutorial
Page 31
Protocol Interoperability

Help building basic plumbing infrastructure for information
exchange

Most value of the TMN business solutions exists in the high
levels




end-to-end network functions
service and customer management
business applications
The technical and business innovation at the protocol level is
non-strategic

Largely useful at element level to exchange information at the
element level
KNOM2001 Tutorial
Page 32
Specification of Operations

Specifications and object models defined in GDMO

Usually very complex and detailed

Define how to do a thing in TMN way:


manage connections, lease lines; report faults, etc.
These standards are overloaded:


implementation of specific management functions (object
specifications of systems or components)?
interface specifications for interoperability purposes (interface
for two operation to interoperate)?

Right Technology for Right Domains
•Managing applications
•Managing customers, software components,
OSS, databases, work groups, enterprises
•Dynamic, real time customer management
SML
•Scalable distribution required
•More computerized, abstract environment
•Managing networks
•Managing object space, functions and relations
•Dynamic environment
NML
•More object level computation required
•Distributed processing environment required
•Managing devices
•Abstracting element information into
•computational objects
EML
•Reasonably stable (static) environment
•Information representation and abstraction
•Open, peer-to-peer communication required

Building Large Scale Distributed Systems

Analyzing the needs

Plan the development road-maps

Always develop for the future changes and extensions

Choosing off-the-shelf middle-ware

Using design patterns

Strategy for management, deployment, education of users
KNOM2001 Tutorial
Page 36
Building Blocks

Always consider that your solution is a configurable, reusable
component of a big solution

Interface design is the primary architectural output

Data management issue is not a strategic design issue
KNOM2001 Tutorial
Page 37
Interfaces

Role of interface is to offer a definition of a service

Interface specification is not enough for the system design, the
object states define the system behavior

Object states


Normalized states
Implementation states
KNOM2001 Tutorial
Page 38
Deployment Model

Deployment model complements the location transparency of
distributed system by addressing the following issues:





what machines exist in the system
which object resides on which machine
what data flows between pairs of machines
what is the system administration strategy (backup, software
upgrade and maintenance)
what is the effect of failure of machines and networks, how to
minimize it
KNOM2001 Tutorial
Page 39
Development Processes

Define development strategies




Business interaction strategy
Customer access strategy
Service interaction strategy
Network independent strategy

Model applications, processes, and information

Select technology (middleware, protocol, language, platform)
KNOM2001 Tutorial

Standardization

The role of standards

Plug and Play?

Interworking vs. interoperating

Solution vs. standards
KNOM2001 Tutorial
Page 41
Object Abstraction

Object abstraction is the most important part of application
modelling

Protocol neutral notation is not enough

Separation of operational model from interaction model

Interaction model is strategic for application management

You must simplify the interaction model
KNOM2001 Tutorial
Page 42
Integration Approaches

Mechanical translation

Can be automated by using tools

One representation of the other

Hard to add value other than interoperability

Re-model networks and functions using technology neutral
modeling

CORBA and OSI as specialization

Better support for cross-domain solutions

CORBA/TMN Integration

Object Modeling

The key of CORBA/TMN integration is the integration of
different object models

Object level integration

Object Granularity


Object granularity is the major problem of the object
integration
Require a generic object model which represents the real network
and is independent from any specific object definitions
