Future ICT Architectures: Perspectives, Requirements and Challenges

Abstract: 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 current 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 rethink traditional Internet design principles and to come up with new architectural concepts for the so-called Future Internet (FI). The FI has certainly a more broad scope than the current one, since it needs to integrate recent advances on Cloud Computing, Software-Defined Everything (radio, networks, systems, etc), Internet of Things, Service- Oriented Architectures, Content-Distribution Networks, Autonomic and Cognitive Networks, and so on.

This tutorial gives an introduction to Future ICT, focused on correlating several emerging technologies. It summarizes perspectives and already identified requirements, challenges, and trends behind key technologies that can be used on this task. More specifically, it covers substrate resources (computing, communications, etc.) capacity, scalability, ubiquity, exposition, and virtualization; Internet of Things (IoT) and Real-World Internet (RWI) approaches; Information-centrism; the role of naming in design, the paradigm of identifier/locator splitting; the role of semantic and context, specially for autonomic and cognitive architectures; mobility, security, privacy, trust; and Software- Defined Everything. The ideas of Internet of Services (IoS) and Service-Based Applications (SBA) are discussed. It discusses simplicity, sustainability and evolvability of design, as well as how to accommodate tussles, regulations, policies, etc. Finally, it briefly presents NovaGenesis future ICT architecture, given an overview of the proposed design, as well as discussing its integration with Cognitive Radio over Fiber Networks, IoT, and user-centric architectures.

Biography: Antonio Marcos Alberti received the degree in Electrical Engineering fom Santa Maria Federal University (UFSM), Santa Maria, RS, Brazil, in 1986, and the M.Sc. and Ph.D. degrees in Electrical Engineering from Campinas State University (Unicamp), Campinas, SP, Brazil, in 1998 and 2003, respectively. In February 2004 he joined the Instituto Nacional de Telecomunicações (INATEL), as an Adjunct Professor. He has experience in teaching more than 8 post-graduation disciplines, including Analysis and Performance Evaluation of Communication Networks, Optimization Methods Applied to Telecommunications and Convergent Networks. In 2012, he joined Electronics and Telecommunications Research Institute (ETRI), South Korea, as a Visiting Researcher at the Future Internet Department. He is a member of the editorial board of the INATEL telecommunications magazine and member of the organizing committee of the IWT (International Workshop on Telecommunications) 2009 and 2011. He was member of the technical committee of Globecom, TEMU, ICDT, IWT and ANSS conferences. In 2010, wrote a book chapter entitled "Future Network Architectures: Technological Challenges and Trends" that discusses technological requirements, challenges and trends towards future network architectures. Also in this matter, he presented the tutorial Future Internet: New Network Architectures and Technologies-Challenges and Requirements, at IWT 2011, Latincom 2011, and IWT 2013. His main working area is communication networks, where he has expertise in project, modeling, simulation, performance evaluation and optimization of such networks. His current interests include future networks design, cognitive and autonomic networks, indirection resolution, entities identification, virtualization and future enabling technologies.
