Abstract

Next generation network

Today service providers are striving to differentiate themselves within this expanding competitive landscape by searching for ways to brand and bundle new services, achieve operational cost reductions, and strategically position themselves in relation to their competition. Many service providers are looking to Next Generation Network services as a means to attract and retain the most lucrative customers.

Because of NGN can be thought of as a packet-based network where the packet switching and transport elements are logically and physically separated from the service control intelligence. This control intelligence is used to support all types of services over the packet-based transport network, including everything from basiv voice telephony services to data, video, multimedia, advanced braodband, and management applications, which can be thought of as just another type of service that NGNs support. On the other hand , How will operations and management be handled in this new enviroment? Although these are all critical questions, we believe the most important issues to be addressed relate to NGN services and how they can be realized in an NGN environment.

Moreover, you can know that, “Why are NGNs important for service providers?, What are the important trends, characteristics, and services in an NGN environment?, What attributes should a Next Generation Service Architecture possess?.
This paper described three critical attributes of this Next Generation Service Architecture
