In recent times, the convergence drives of two powerful technologies — wireless and the Internet — through IPv4/v6 protocol has led to emergence of what we call next-generation networks (NGNs). NGN is no more a network of mere computers but a connected conglomeration of varied networks with diverse physical properties, with plethora of network elements, along with variety of real time multimedia applications.
This book covers topics, all about NGNs, that cover the entire gamut of technology challenges from physical layer to application layer including security. These topics are written from a perspective of both academic elegance and industrial applications.
