CHAPTER1: INTRODUCTION

Introduction

Traditional telecommunications networks (Post 2007 1)were developed to transmit voice call only but in Next Generation Network can carry including voice, video, email on a single platform. This is the main advantage to migrates NGN .According to the BT's planned £10 bn will roll out 21st Century network by 2012 will make the United Kingdom the first country to replace its current telephone network with an NGN . NGNs are surprisingly cost effective to operator and new services to the consumers but there are also some new challenges as well in maintain the quality, reliability, and security of communication compared to incumbent telephone networks (Bauer 2006 59).

When the telecom age began, from that point networks are using different type of technologies to carry out different type of communication. For instances, BT maintains 16 separate communication networks in the UK including PSTN. PSTN is a traditional circuit switched based network where data travels a certain path which is defined at the start of the call and reserved until the call ends. Oppositely, in NGN packet based network where data are split up into many packets that may travel along different routes and rebuild the data when they reach their destination.

So the basic idea of NGN is to change all types of services and form a single network(Armstrong Mark Vickers 2006 14). This network convergence would enable the operators to save cost and provide new services from different types of data from a singular network platform NGNs are more adaptable because they do not need to physically upgrade for supporting new types of service. The network simply transport data, while services are controlled by software on computer that can be located anywhere, so it means the third party software can easily launch their new services. This is also a big advantage to the NGN environments.

Technically speaking and taking a scientific point of view, NGN is defined by the International Telecommunication Union (IUT) as a'' packet based network making various uses of broadband providing various services including telecommunication services, QoS-enabled transport technologies and in which service related function are independent from underlying transport-related ...
