Next Generation Internet Bill St. Arnaud CANARIE Inc www.canarie.ca Bill.st.arnaud@canarie.ca Observation > Dennis Jennings original director for NSFnet > The original Internet was neither pre-ordained or a given > Internet was
– Still ignoring it
> 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.
– FIND – Future Internet Directions - $40m PI driven research program – GENI – Global Experimental Network Initiative – proposed $350m infrastructure to support next generation Internet research
– NewARCH – New Internet Architecture – CORONET - Dynamic Multi-Terabit Core Optical Networks: Architecture, Protocols, Control and Management – CBMANET - Control-Based Mobile Ad-Hoc Networking
– INTERNET OF THE FUTURE – – FIRE -Autonomic networks and self organizing networks
– NGI – Next Generation Internet Initiative
– Now it is.
– Regulation (or lack of)? – Continued investment and innovation? – Options for user choice? – Deployment of new services? – Health of the value chain?
– Role of advertising?
– Usual place to start, but I will get to it later.
– 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.
– Design alternatives will have important influence on personal choice, control, innovation, etc.
– More like 10 to 15 years
– E.g. NREN’s move towards fully owned optical hybrid networks
– Network Neutrality debate – Walled garden approaches or – Verticalization

– Networks and service infrastructures underpin economic progress and the development of our societies
400 million internet enabled devices
– Of a growing and changing demand
«things », for convergence in networks, services and devices
– Current technologies can be, and need to be improved significantly
– Europe is in a leading position: Industry, technology and use

> Scalability
– devices (users AND nodes, mostly wireless) will outnumber humans by several orders of magnitude – Not only numbering: Service-centric networks invalidate the source-destination approach of the Internet (semantic addressing, space-aware models…) – Need to overcome the intrinsic limitations of a centralised control (self-management, self-organisation), multidisciplinary approaches to cope with complexity (e.g. bio-inspired) – Multiple points of attachments to the infrastructure, edge diversity – Routing
> Suitability for ad-hoc/multi-hop/mesh networking
– disconnected operation is common (opportunistic, trust and privacy, …)
> Mobility
– Mobile IP (or MIPv6) not effective, overhead
> Transparency
– QoS??? – Web of trust? – Usability
> Security
– How to embed it, how to cop
> Machine-to-machine com

> Broadband networks, whether wireless or FTTx, overbuilders, municipal or customer owned, requires huge capital outlay with a big risk of slow take-up. In addition:
– subject to intense competition from incumbents – High churn – Low takeup – “Tyranny of the takeup”
> Consumers unwilling to spend more than $40/mo for broadband
– Generally prefer lower cost, rather than higher bandwidth
1034_3-6084717.html – Margins are very thin, even for incumbents
> Many companies starting to offer free broadband, both wired and wireless
– Inuk, Sky, TalkTalk, Google, Microsoft, Cable and Wireless etc
> The real winners in the broadband game are those providing advanced services
– Google, Inuk, Yahoo, Skype, Joost, etc – CBS is going to deliver prime time TV over Internet this fall – one day ahead of broadcast TV
– May serve as possible model for telcos
– There may be others- this is not intended to be definitive or exclusive
