Korea Telecom 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 - service provisioning - flow-through. policy-based mgmt, 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

Korea Telecom Dynamic Configurability new/modified network type new/modified service type scale up/down of existing networks and services Components + Configuration Framework Components + Configuration Framework

Korea Telecom Emphasis on Service Management CNM service provisioning service monitoring for proactive management flow-through operation

Korea Telecom Business Support source of valuable business data for - business support system - network planning and dimensioning - advanced customer care - generating new service base system for maximizing telecom business value tight and seamless integration with business data warehouse network & service management system business support system network planning system

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

Korea Telecom Dynamic Integration Framework as Additional Common Frameworks entity 1 entity 2 entity n entity 3 entity 1 entity 2 entity n entity 3... integration coordination entity : integration relationship meta level information dynamic integration framework in addition to existing management frameworks. Avoiding direct, ad hoc integration approach Mediation-based framework supported by meta level information on networks and services dynamic, ad hoc approach mediated integration approach

Korea Telecom 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

Korea Telecom Standardization on Network Management network element level network level service level business level per-technology vendor-driven Bottom-up Approach Top-down Approach business-driven direct benefit to network/service providers

Korea Telecom 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.
