Wu, IEEE Fellow / ATMco Founder, USA Vladimir Zaborovski, Prof, Technical University/Robotics Institute Saint-Petersburg, Russia Open discussion: INTERNET’s topics, journals,directionsINFOWARE Conference, August 22- 29th, Cannes, FranceSlide 2

Panel motivation Future Internet (FI)Why to discuss, here, again? Nowadays the Internet has significant impact on all socio-economicand life aspects of the global societyInternet – became (some opinions) the 5th power of the societyMany (int’l) efforts to define/re-define the future directions of FI Research groups, academiaIndustryStandardization organizationsGovernmentsUsers . Still – there are many open FI issues, including discussion/revisionof the fundamental conceptsFI: very large collection of topics IEEE Comm Magazine –July 2009: “The term future Internet has gained a lot of interest recently”“Several research funding organizations have decided to support thedevelopment of the FI; a growing number of research projects arebeing established.”“There is, however, currently no agreement on what the technology ofthe FI will look like; nor is there agreement on what the goals of thevarious competing future Internet activities are ”INFOWARE Conference, August 22- 29th, Cannes, FranceSlide 3

Panel agenda Note: Two hours panel only Short, general introduction and presentation ofcurrent Internet limitations and some FI challenges(moderator)Specific issues (selection) and possible solutions(panelists)Then, the audience is kindly invited to expressopinions.KEY issues on FI concepts and design: evolution?or clean slate approach?or something in the middle?middle?INFOWARE Conference, August 22- 29th, Cannes, FranceSlide 4

Summary on Internet Evolution and Status (Partial Sources: Report from the National ICT Research Directors Working Group on Future Internet(FI) of the EC on Information Society and Media- Nov. 2008) A.Peltomäki, Stimulating an Innovation Ecosystem for Future Internet Technologies,EC Information Society and Media Directorate-General, Lulea, Sweden June 2009, Nowadays is a global infrastructure supporting the economy as well as theprovision of societal services Pervasive /ubiquitous; 25% of the world population - access to Internet Mobility and nomadic usages are becoming the norm By 2012, at least 1 Bn of Internet users will use mobile as their only accessmeans, adding to the today 1.5 Bn of fixed users It has enabled user and consumer empowerment, through the emergence ofeCommerce and social networks Tool for modernisation of many domains: emerging - eEducation,eGovernment, eHealth, etc. Expected to contribute significantly to solve emerging challenges such asclimate change and energy efficiency.INFOWARE Conference, August 22- 29th, Cannes, FranceSlide 7

Summary on Internet Evolution and Status (cont’d) It has favoured innovation and the emergence of new disruptive businessmodels: in 2008, 300 million use VoIP Skype Software: novel A/V consumption models - e.g. YouTube (global usersdownloading 10 hours of video/min from that site Web 2.0 and social networks are growing. Popular social sites attract morethan 120 million regular users. Web 2.0 apps. will be more and more used bybusinesses and individuals. The emergence of 'enterprise 2.0' will bringsignificant benefits to companies and SMEs in particular Support for entrepreneurs’ creativity: its native openness, made possiblethousands of innovation world wide, to develop a huge range of applications There is a recognized - clear correlation factor between growth of broadbandInternet access and employment growth Multiple societal impacts of the Internet are nowadays widely accepted by thepolicy makers ( issue like - “Future of the Internet economy”)INFOWARE Conference, August 22- 29th, Cannes, FranceSlide 8

Summary on Internet Evolution and Status (cont’d) An ever richer content and media environment Content is clearly one of the main drivers of Internet changes Every year, the Internet traffic grows by 60%. This is mainly due to video,and will be further amplified with the advent of on-line 3D content. The emergence of an Internet of “things": In the near future, it will bepossible to interconnect billions of objects and devices New types of applications combining information of the virtual world witha perception of the physical world have enormous economic prospects Challenges: Internet has been designed 30 years agoNumerous technical challenges arise with the expansion of the InternetNew usage patterns and requirements not previously foreseen lead to theneed of a fresh look at the main Internet architecture itselfTrust and security – serious future issuesINFOWARE Conference, August 22- 29th, Cannes, FranceSlide 9

Often academic writing is full of technical jargon-technical jargon is an essential ‘tool of the trade’ -jargon eases communication –speeds up exchange of ideas between other professionals-BUT it can also obscure: creates ‘them’ (ordinary ‘laypeople’ culture and [implied] elite ‘professionals’) Beginners don’t always know enough to see errors. Strategies for ‘Being
