illy Media, Inc., 2004. Chapter 34 Report: NGNM Framework and Adoption Strategy This chapter is a report analyzing Next Generation Network Management Framework and discussing an adoption strategy for using the same. The report takes into consideration the most important concern of the service provider on how they can effectively utilize the functionality rich legacy solution in adopting a framework that is aimed at next generation management standards. 34.1 Report Overview With the evolution in technology, new and improved networks are coming up in the market and the legacy NMS solution is not scalable to manage these next generation networks or its elements without considerable rework. The capital and operational expenditure in managing these NMS solutions keeps on increasing. The problem most service providers face is either a single legacy NMS that is not scalable and takes considerable effort to modify in managing a new network or the use of multiple NMS solutions for different networks. There is a lack of experienced professionals who have knowledge of multiple NMS and it is a considerable overhead on the operators to understand and work with multiple NMS. This leads to an increased need for NMS solutions that can cater to management of diverse networks in a multiservice, multitechnology, and Fundamentals of EMS, NMS and OSS/BSS multivendor environment. Another important factor influencing NMS architec- ture is mergers and acquisitions among the key vendors. Ease of integration is a key impediment in the traditional hierarchical NMS architecture. The networks will continue to evolve and the only way to perform network management in a cost effective and operational friendly manner is the migration to a solution that solves the challenges. Standardizing bodies are coming up with standards and guidelines in develop- ing next generation network management (NGNM) solutions to address current challenges in network management. The major issue here is that the current legacy NMS are functionality rich and highly spe
