Outline

Changes in Telecommunication Market Impacts on Telecommunication Network Management Meeting the Challenges Conclusions

Korea Telecom

It’s Diverse and Fast Changing

Demands are met by introducing new networks and services resulting in diversity in networks and services

The speed of change is getting faster making it difficult to catch up with existing paradigm

No more ad hoc, case-by-case approach

Need for systematic, framework-based solution

Korea Telecom

Emerging Importance of Network and Service Management

operations “support” system- customer interaction,- CNM

- serviceprovisioning- flow-through.policy-basedmgmt,

From “support” system to main service stream

Korea Telecom

Virtues of the Upcoming Management Systems

Integrated management for handling diversity Dynamic configurability for fast adaptation to changes

fast adaptation of newly emerging networks and services Emphasis on service management Management system as the core for business information, decision

making, and quality management

Korea Telecom

Integrated Management

Different integration contexts integration of management functions, integration of network elements with different management interfaces, integration of client-server networks (e.g., IP and ATM networks), network and service integration, service composition, etc.

Different integration patterns and methods no well-proven, widely-accepted framework for integration need for common integration framework that supports faster

application integration

Component and Middleware Technology

Using component technology is becoming virtually the common practice for rapid development of management systems e.g., Corba-based network management system component technology is evolving, making development more

easier and secure (e..g, Enterprise JavaBeans and Corba Components)

For telecom operators to get more benefit from the technology… Continuous generation, publication, and standardization of

management components is encouraged. enables operators to focus more on business-related activities

Standardization on Network Management

Working with Legacy Systems

Legacy systems as “another” component of the whole management system importance of adapters

Coping with monolithic structure of legacy systems service management and network management features

merged into a single but optimized mass different abstractions rather than modifying the internals of

legacy systems service management level mediator network management level mediator

Korea Telecom

In Conclusion

The telecommunication world is rapidly changing. Changes in telecommunication world is pushing for more role in

telecommunication network management systems. The need for common framework for dynamic integrated network

management system. Importance of common management components.
