Introduction

Abstract

It starts by addressing some of the problems with current Internet networks, its core architecture and its evolution model. Current architectures are typically developed around layered models, and deficiencies have been shown, such as lack of support for QoS and seamless mobility, security vulnerabilities, and address shortage. The various forms of unwanted traffic, including spam, distributed denial of service, and phishing, are arguably some of the biggest problems. Changing business models are likely to have impact on the network. Privacy and accountability are other major issues. Next, a brief description of the 4WARD project is provided. It is followed by an overview of the current research and development activities being held in Europe, USA and Japan. It ends with a global view of the contents of the book.
