Preface
It will be fascinating to look back in the years ahead and note the convergence of two formerly separate technologies, namely telecom technology and information technology. The former one originates from the telephone world and is based on dedicated architectures with circuit-switched point-to-point connections designed for real-time services. The latter comes from computer communication with flexible architectures and packet-based communication. Due to the emergence of different kinds of communication and networking technologies and the foreseen proliferation of different and specific types of services supported by these technologies, both are merged in a mixture of dedicated and flexible architectures, clearly targeting the use of the Internet Protocol suite as the basis communication protocol. Nevertheless, it appears recently that traditional network control strategies developed in the last decade are not sufficient to handle the complexity and diversity of information in use that we see today. Over the years, the continuous technological evolution and the development of new applications and services have steered networking research toward new problems, which have emerged as the network evolves with new features toward what is usually referred to as the future internet, which has become one of the basic infrastructures that supports the world economy nowadays.
In fact, there is a strong need to build a new network scenario, where networked computer devices would proliferate ...
