The research community worldwide has increasingly drawn its attention to the weaknesses of the current Internet. Many proposals are addressing the perceived problems, ranging from new enhanced protocols to fix specific problems up to the most radical proposal to redesign and deploy a fully new Internet. Most of the problems in the current Internet are rooted in the tremendous pace of increase of its use. As a consequence there was little time to address the deficiencies of the Internet from an architectural point of view.
While the Internet is hardly “broken”, it has proved unable to integrate new ideas, new architectures, and provide paths for future integration of data, voice, rich media and higher reliability. The reason is that the basic concept of the Internet as an end-to-end packet delivery service has made its middle layer, networking services through TCP/IP, untouchable.
