Be sure to view it in Page Layout so that you can see the footnotes. I did not at first, and missed them entirely, which was very confusing, as there are numbered references listed at the end as well. http://www.ictconsulting.ch/reports/NEC2007-OHMartin.doc Olivier has retired, but apparently keeps busy as a consultant. He was a major player in CERN networking from the very start of things. In the early days, CERN was the hub of European Internet Protocol networking, and it still is a major player because of the HUGE amounts of data that are generated by the accelerators and shared globally. State of the Internet & Challenges ahead "How is the Internet likely to evolve in the coming decade" To be published in the NEC'2007 conference proceedings (see footnote (1) below) Olivier H. Martin (2) ICTConsulting, Gingins (VD), Switzerland Abstract After a fairly extensive review of the state of the Commercial and Research & Education, aka Academic, Internet the problematic behind the, still hypothetic, IPv4 to IPv6 migration will be examined in detail. A short review of the ongoing efforts to re-design the Internet in a clean-slate approach will then be made. This will include the National Science Foundation (NSF) funded programs such as FIND (Future Internet Network Design) and GENI (Global Environment for Network Innovations), European Union (EU) Framework Program 7 (FP7), but also more specific architectural proposals such as the publish/subscribe (pub/sub) paradigm and Data Oriented Network Architecture (DONA). Key words: Internet, GÉANT2, Internet2, NLR, NSF, GENI, FIND, DONA, OECD, IETF, IAB, IGF, ICANN, RIPE , IPv6, EU, FP7, clean-slate, new paradigms. 1 Introduction While there appears to be a wide consensus about the fact that the Internet has stalled or ossified, some would even say that it is in a rapid state of degeneracy, there is no agreement on a plan of action to rescue the Internet. There are two competing approaches, evolutionary or cleanslate. While a clean-slate approach has a lot of attractiveness it does not seem to be realistic given the time constraints arising from the fact that the IPv4 address space will be exhausted in a few years time, despite the fact that IANA (3) (the Internet Assigned Numbers Authority) is about to allow an IPv4 "trading model" to be created (4). Therefore, the migration to IPv6 looks "almost" unavoidable, though by no means certain (5), as the widespread usage of Network Address Translators (NAT) and Application Level Gateways (ALG) is both unlikely to scale indefinitely and/or to meet the ever evolving Internet users" expectations and requirements. However, new ideas arising from more radical and innovative approaches could probably be retrofitted into the existing Internet, e.g. self-certifying names, à la "DONA" (6). The purpose of this paper is to raise awareness about the ongoing initiatives with a special emphasis on technical issues and possible remedies or solutions, it does not attempt in any way to be exhaustive as the subject of the Internet evolution including the societal, ethical and governance aspects are far too wide and complex to be addressed in a single article. _________________________________ 1 http://nec2007.jinr.ru/ 2 Olivier.Martin@xxxxxxxxxxxxxxxx 3 http://www.iana.org 4 Could IP address plan mean another IPv6 delay? - Network World 5 the cost/benefit ratio is still far too high to build a convincing business case 6 Data Oriented Network Architecture Regards, - --SteveG - ------------------------------------------- Archives: http://www.listbox.com/member/archive/247/=3Dnow RSS Feed: http://www.listbox.com/member/archive/rss/247/ Powered by Listbox: http://www.listbox.com ------- End of Forwarded Message _______________________________________________ IETF mailing list IETF@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
