Nowadays, there is a big debate on redesigning the Internet to meet current and future society needs. In this sce- nario, it is important to consider that actual Internet was designed when computing, communication and storage sub- strate resources were very limited. Technology evolution was much slower than today. In this context, some questions are: how technology evolution will affect design this time; is there any impact of accelerated technological evolution in the choice of candidate technologies; how designs can incorporate technological advances that are increasingly more frequent? This paper contends that: technology evolution is a stronger requirement this time; substrate resources evolution needs to be decoupled from software - and virtualized; and research, development and experimentation needs to be online - integrated on the architecture itself. The paper proposes and discusses two scenarios for online development on Future Internet.

  • 1. Some Impacts of Technology Evolution on the Design of a New Internet Antônio Marcos Alberti Instituto Nacional de Telecomunicações - INATEL 510 João de Camargo, Santa Rita do Sapucaí, Minas Gerais, Brazil alberti@inatel.br http://antonioalberti.blogspot.com
  • 2. Outline • Motivation and Contextualization • The Role of Technology Evolution on FI Design (FID) • Two Scenarios to Accelerate Technology Evolution • Requirements and Challenges Towards the Vision of Online R&D • Conclusion
  • 3. Motivation and Contextualization (1/4)• The Internet was designed at a time where substrate technologies, such as digital computing, communication and storage resources, were very limited.• The first packet switching test of ARPANET was done in a TX-2 computer with 64K 36-bit words of core memory. TX-2 Module. Source: Wikipedia.
  • 4. Motivation and Contextualization (2/4)• In 1973, ARPANET had 40 nodes and the assumption was that it would not have more than 256 networks! [Leiner 2009]• Soon this estimate proved to be conservative.• Even in the early 80‘s, the number of hosts on ARPANET already presented a exponential trend. Question: Is it possible to predict how Internet numbers will evolve?
  • 5. Motivation and Contextualization (3/4)• Moore’s Law - Used by decades to predict technological developments in terms of computing capacity.• Ray Kurzweil - Law of Accelerating Returns - two positive feedback loops occur during some technology evolution process. Question: Is the current Internet prepared to face such exponental growths?• Redesign is required.
  • 6. Motivation and Contextualization (4/4)• However, this time the technology landscape is quite different from the 60’s - it is much more dynamic, complex and diverse.• Objectives: Question: How technology evolution will affect design this time? Question: How designs can incorporate technological advances that are increasingly more frequent?
  • 7. The Role of Technology Evolution on FID (1/2)• Question: How technology evolution will affect design this time? • Technology evolution will deeply affect designs this time - the pace of change is impressive. • To accomodate technology evolution in a flexible, homogeneous, holistic, and convergent way is a key issue! • Besides, challenges that can not be addressed today, could be in a few years - estimatives need to consider exponential growths. • Impacts of evolution are dual-faceted: they create not only more capacity, ubiquity, and connectivity, but also more scalability and complexity drawnbacks.
  • 8. The Role of Technology Evolution on FID (2/2)• Question: How designs can incorporate technological advances that are increasingly more frequent? • Making R&D cycles online - the vision of Online R&D: 1. Indirect R&D over a developing facility compatible with an operational substrate resource provider. 2. Direct R&D over an operational substrate resource provider. 3. Indirect R&D over a third party experimental facility compatible with an operational substrate resource provider.

  • 11. Requirements and Challenges Behind Online R&D• All hardware needs to be virtualized - however, FI research is not so generic.• The partners of online R&D need to trust each other - a trustable R&D business ecosystem needs to be structured.• Security and privacy need to be rethinked on the context of such ecosystem.• Real-time resource virtualization is important to enable deployment of time-sensitive functionalities on software.• Current autonomic initiatives are little concerned with accomodating acclerating technology evolution - FI requires better evolvability and sustainability.
  • 12. Conclusion• Online R&D accomodates technology evolution of substrate resources, software systems, virtual entities, and frameworks.• The main advantages are flexibility, transparency, conformity to the user requirements and proximity to the operational scenarios.• Virtual operators can participate at distance from milestones on R&D schedules.• R&D of new substrate resources consider virtualization of their functionalities to operational parters in the business ecosystem.
  • 13. Conclusion• Online R&D of customized networks can be done over slices of virtualized resources.• When R&D ends, the customized network is simply made operational.• The online R&D facilities evaluation, comparison, migration and evolution of substrate and overlaid resources.• In summary, designers and developers of the FI are also active part of the digital business ecosystems they are creating.
