Abstract

This chapter presents results of practical experience with NGN and mainly its application layer. The presented university laboratory based mainly on the open source software follows the evolution strategy of NGN. This evolution includes a way from using SIP-based VoIP architecture to the IP Multimedia Subsystem (IMS) implementation of standardized NGN. The background of the standardization process is briefly presented as well. Our focus on application layer is motivated by its existence and similarity in various NGN implementations. In this chapter, we also discuss in detail three applications and services: multimedia streaming, security, and AAA service. This chapter shows the ability to build an NGN network for testing purposes. However, we prove that application layer, unified application access, and consequently convergence are main foundations of NGN.
