Re: <nettime> Olivier Auber: Network symetry and net neutrality |
Dear Florian, Concerning, http://www.youtube.com/watch?v=8c0sX6j5D_c , I think you missed the key message of this prostatic guru. The question is not whether the multicast protocol is working or not, and why (I'll talk however of this issue below) but to clarify the notion of "symmetry" (of protocols), and to show that an asymmetrical network leads AUTOMATICALLY to current state of the Internet, that is to say, a centralized network, near to implode. Not to question the economic and money paradigm, GAFA seem to be going straight for what the guru called a "triangular trade of personal data" between them and States on the backs of enslaved users. Thus we see how might look like transhumans that Google makes us sparkle, to say nothing of immortality ... Regarding multicast, you mention a paper written by a DARPA-funded scientist who can not imagine one second that the peers of P2P networks may well become also kind of multicast routers, which would transform the said P2P networks to P2P^10 networks! Second, the concept of multicast is older than the Web (Steve Deering 1989) and began to be implemented on the Mbone also before the web: http://en.wikipedia.org/wiki/Mbone Finally, yes, the prostatic guru tells the truth: the multicast protocol is artificially used in an asymmetric fashion for IPTV. http://en.wikipedia.org/wiki/IPTV Why multicast has not survived to the web? This is a complicated issue that probably has common points with the VHS war of the 70s http://en.wikipedia.org/wiki/Videotape_format_war You might be too young to have experienced the Multicast/web war of the 90s. To my knowledge, nobody has written about that war, probably because it is too recent and it is far from being over. However it is real, with real victims, including scientists who worked on multicast networks all over the world, who have seen their budgets cut to zero (with the exception of those who have agreed to work on its adaptation to crappy TV apps), and then all of us today, who are the playthings of a network that claims there is no alternative and that leads us into the wall. Van Jacobson, one of the main promoters of Multicast has written in 1995: "How to kill the internet? Easy! Just invent the web !" ftp://ftp.ee.lbl.gov/talks/vj-webflame.pdf Berners Lee in some of his recent statements, is not far from agreeing with him. Van Jacobson is still active. Here he admits that the multicast is not "scalable" in the current economic rules. However, he seems to refrain from thinking of new rules in the sense that the prostatic guru indicates (symmetrical monetary creation such as http://openudc.org). http://video.google.com/googleplayer.swf?docid=-6972678839686672840 There, he worked with others to develop some patches inspired by multicast, that would differ the collapse of net. But, AMHA, it's just DIY ... http://en.wikipedia.org/wiki/Content-centric_networking -- Olivier ==== On Sat, Feb 23, 2013 at 4:06 AM, Patrice Riemens <patrice {AT} xs4all.nl> wrote: > Networks symmetry and Net Neutrality > by OlivierAuber [...] > However, there are also symmetrical protocols on the Internet. > One may think about peer-to-peer protocols such as the ones used > over mesh networks, but more fundamentally, the general model > of it is called "Multicast", defined as a part of IPv6, which > allows "all-to-all" relationships without the intervention of any > particular center, if it is the Internet in its entirety. To my knowledge, the opposite is correct. Multicast one-to-many transmission of network packets, effectively the same as broadcasting. It's the opposite of peer-to-peer.
