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

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

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.

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.
