This is the third part of a Future Internet Tutorial presented at IWT 2011. See: www.inatel.br/iwt

The Internet has invaded most aspects of life and society, changing our lifestyle, work, communication and social interaction and giving us expectations about new forms of interactions and access to global knowledge. Application and user demands on the Internet are increasing with mobile technologies and media content. Nevertheless, the Internet today is a complex agglomerate of protocols that inherits the grown legacies of decades of patchwork solutions.

There is a common consensus that the Internet needs improvement. Nevertheless, there is not yet a shared vision on how this may happen. As a direct consequence research programs have started worldwide to re-think traditional Internet design principles and to come up with new architectural concepts for the so-called Future Internet (FI).

The Future Internet Tutorial provides an overview of Future Internet research directions and trends. It presents the Future Internet research initiatives around the world and the efforts to establish experimental facilities for FI research. The tutorial gives an introduction to new Future Internet architectures that are currently under discussion and related technologies. Among the approaches discussed are addressing and routing concepts, adaptability, autonomicity, self-*, *-aware and manageability, virtualization, neutrality, openness, diversity, extendibility, flexibility and evolvability. The tutorial also presents some interdisciplinary aspects related to artificial general intelligence and bio-inspired ICT.

  • 5. Technology Evolution The Law of Accelerating Returns: Two positive feedback loops 1. Selection of the more capable techniques of a certain stage to build the next stage – increases the rate of progress exponentially, reducing required time to obtain the same results. 2. Selected process becomes more attractive than others and begins to catalyze resources to it – starts to evolve even faster, experiencing an additional exponential growth over the 1st.
