Performance Management in Network Management System

Telecommunication networks are becoming more and more complex, as a result telecommunication operators are facing big operational problems to monitor or manage the performance of the system. Telecommunication Management Network (TMN) is the framework developed by International Telecommunication Union - Telecommunication Standardization Sector (ITU-T) for managing telecommunications networks and services. Performance Management (PM) is one of the five core management functionalities identified by ITU-T. A Network Management System (NMS) falls under the Network Management Layer of the TMN. This paper provides the foundation for understanding PM principles and PM operation workflow. Architecture for a PM System in NMS is proposed and the challenges in the implementation of PM System and methodologies to overcome these challenges are observed.
