Abstract

The next generation network is a future based network providing next generation services such as internet protocol television (IPTV), online gaming, video on demand etc, based on IP protocol in the presence of core network. This research based paper discusses the architecture of next generation network (NGN), challenges, solutions, reliability, pros and cons. The main objective is to investigate the effectiveness of NGN providing next generation services. Moreover, this paper also discusses the basic customers’ needs and futuristic trends. Different technologies providing different services are also reviewed. The term next generation network (NGN) is used to support telecommunication network architecture, supporting technologies and services. In addition to it, conventional public switched telephone network (PSTN) data, voice communication and video services are also supported and discussed on the basis of NGN. The information carried through this network is based on packet switching which is also known as Internet network.

Key words: Next generation network (NGN), internet protocol television (IPTV), mobile, public switched telephone network (PSTN), architecture, packets, WiMax, technology.
