In the first ten chapters of this book we considered various aspects of telecommunication networks: their components, how they are constructed, and the way that voice and data is carried. Now, in this final chapter we take a holistic view of how all the pieces are put together, how the end-to-end service provided to the users is managed, and how the networks are progressively enhanced and developed to take advantage of new technology. Specifically, the so-called next-generation network (NGN) concept is examined. It is hoped that by the end of this chapter readers will have gained an insight into the intriguing question raised in the Foreword to the book, that is, whether it is right to assume that all communications will eventually move onto the Internet.
