Observation > Dennis Jennings – original director for NSFnet > The original Internet was neither pre-ordained or a given > Internet was fortunate series of accidental events > We could have easily ended up with X.25 or ATM has the foundation of the Internet as we know it today > Large part of its success was the telcos ignored Internet development for the first 20 years – Still ignoring it > Will a 20 year pure research program result in a better Internet? > Future Internet has to be anchored with practical implementation issues and business models > Critical role for NRENs & GLIF
NSF/OECD workshop – Jan 31 Social & Economic Factors Shaping the Future of the Internet > In terms of the Future of the Internet there is a current window of opportunity to consider economic, social and regulatory issues in relation to work being undertaken under the umbrella of the Global Environment for Network Innovations (GENI) and the OECD Committee on information and communications policy (ICCP). > The NSF/OECD Workshop will bring together who’s who of economists, policy- makers, social scientists and technologists, to consider a broad range of factors which have relevance for the future of the Internet. > In considering a new infrastructure, such as GENI, it is important to highlight the Internet’s growing role as a driver of innovation leading to economic growth and social well-being. Specifically, Workshop participants are asked to draw lessons from the applications and use associated with the evolution of the current Internet and to identify the features that have been critical to the Internet’s success. > At the same time, the Internet faces many challenges which are not only related to its technical limitations and it is increasingly clear that many of the problems the Internet has encountered concern economic and social issues.
The research challenge > The Internet is a tremendous success, but… > Can we meet tomorrow’s needs by incremental improvement of today’s design? > NSF and its research community have concluded that they must take a leadership position with respect to revolutionary network research, and must provide suitable infrastructure for this research.

Next Generation Internet approaches > Incremental – Next Generation Internet will be achieved through small incremental improvements to existing Internet – E.g. Phosphorous, NGI > Federated – Next Generation Internet will be a federation of different networks with different architectures and protocols – E.g. CA*net 4, NLR, SURFnet > Big Bang – Next Generation Internet will have to be a complete fresh start – E.g. NewARCH, GENI
Next Generation Internet Initiatives > USA – NSF – FIND – Future Internet Directions - $40m PI driven research program – GENI – Global Experimental Network Initiative – proposed $350m infrastructure to support next generation Internet research > USA DARPA – NewARCH – New Internet Architecture – CORONET - Dynamic Multi-Terabit Core Optical Networks: Architecture, Protocols, Control and Management – CBMANET - Control-Based Mobile Ad-Hoc Networking > EU – INTERNET OF THE FUTURE – – FIRE -Autonomic networks and self organizing networks > JAPAN – NGI – Next Generation Internet Initiative
FIND: An NSF challenge question > 1) What are the requirements for the global network of 10 or 15 years from now, and what should that network look like? > To conceive the future, it helps to let go of the present: > 2) How would we re-conceive tomorrow’s global network today, if we could design it from scratch? – This is not change for the sake of change, but a chance to free our minds.

Security and reliability > Define the objective broadly. – “Classic” security, availability, resilience. > Hard because: – Many problems are in the end-hosts. – Many problems involve a balance of interests. • Among actors, states and societies. • We don’t have agreement about the objective. – Different contexts call for different answers. – We don’t have a coherent approach.
Economic landscape > In 1975, it was not clear to the early designers that we were designing the landscape of investment and competition. – Now it is. > Could we do a better job to shape: – Regulation (or lack of)? – Continued investment and innovation? – Options for user choice? – Deployment of new services? – Health of the value chain? • Consider the role of facilities providers, for example. – Role of advertising?

Technology drivers > New network technology. – Usual place to start, but I will get to it later. > New computing technology. – Whatever computing is, that is what the Internet should support. – The Internet grew up in a stable “PC” time. – The cellular industry evolved independently. – Tomorrow: many different views; sensors, cell phones, embedded processors, $100 laptops, etc. > Rich space of services and servers. – Design alternatives will have important influence on personal choice, control, innovation, etc. Source: David Clark MIT
Summary--integrative visions > What are candidate designs of a future global network suited for the needs of 2020? > What are good design principles for large scale future distributed systems and services? – Alternative approaches will lead to different outcomes in the socio-technical space.
Van Jacobson > Content Centric Networking > Move from channels to platforms – The old Internet and telecom was focused on setting up communication channels to distribute data – routers, switches, paths, etc – But data should not have locality > Convergence of cyber-infrastructure and next generation Internet > Integration of Grids, Web 2.0, SOA, P2P, Enterprise 2.0 and NGI > Possible significant impact on new business models
ISOC – Internet 2020 > Not “Internet 2” too or similar incremental initiatives > Radical transformative network originating from research community > Pervasive Information systems > Terabit to the desktop
Internet 2020- What will be there > Optical of course – Terabits to the Desktop > Hybrid networks – Generic packet based IP-network and – Dynamically established high speed end-to-end optical circuits • Bandwidth on Demand (BoD) • Lambda Grids
Solutions? > Require interdisciplinary research > Long term research, not restricted to 4 years – More like 10 to 15 years > Meanwhile we see short term partial fixes – E.g. NREN’s move towards fully owned optical hybrid networks • Works within NREN > Commercial providers work on local solutions – Network Neutrality debate – Walled garden approaches or – Verticalization
GENI: Vision & Implementation A shared facility that allows: > Concurrent exploration of a broad range of experimental networks and distributed services > Interconnection among these experimental networks and with the Internet > Real users utilizing experimental services > Observation, measurement, and recording of the resulting experimental outcomes > Funding for new router architecture already underdevelopment > Third R&E network in the USA Source: Peter Freeman NSF

EU Internet of the Future Network & service infrastructures Rationale – Networks and service infrastructures underpin economic progress and the development of our societies • 2 billion mobile terminals in commercial operation, 1 billion Internet users, 400 million internet enabled devices • Determining factor in business development in all sectors – Of a growing and changing demand • For more, and more user control of content/services, for interconnecting «things », for convergence in networks, services and devices – Current technologies can be, and need to be improved significantly • for scaling up, for more flexibility, for more security and dependability – Europe is in a leading position: Industry, technology and use • Networks equipment and services, business software, security, GRIDs technology Source: Fabrizio Sestini EU-Canada workshop
