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

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

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

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

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.
