    IPv6 is nothing, it was just created because we are running out of IP addresses quickly. The future as I see it is mass distribution of media. Instead of running out and buying movies you could download the whole dvd and watch that.

      First we need download speeds that are even close to our Asian neighbors.

      It is pathetic that even poor people in South Korea have lines for 20 bucks a month at 25 mbps. America the leader in tech? I beg to differ.

      • South Korea is also just a *teensy* bit smaller than the US. The infrastructure costs required to wire all the areas in the US with 25 Mbps speeds would be enormous. Also, just how many people can afford 20USD/month in South Korea? Does this include "the poor people"? Quit trying to compare two vastly different situations just to bash the US.
        • These comparisons are normalized to scale. Why doesn't *anywhere* in the US, like a Korea-sized area around NYC encompassing 50M people, get 25bps for $20? Where lots more people have $20:mo? Could it be that the situations are vastly different in the agressiveness with which the respective telcos are pursuing innovation? Or are you saying that Koreans are somehow innately more bandwidth-hungry than Americans?
          • Verizon just laid fiber in my neighborhood (suburban Pennsylvania) and are rolling out 15mbps for $40/month. Not bad.
            • I get 6Mbps residential RoadRunner for $50:mo in NYC, which used to cost $25K over fractional T3 only to businesses, so I'm kinda happy. By the time they deliver 25Mpbs for $20:mo, Koreans will have 155Mbps.
          • Korea is a lot more densely populated than the USA, or most of the western world, as far as I know. It makes a big difference on returns if the infrastructure you're laying down is reaching 10 times as many people per unit length.

            That doesn't explain the excellent, although probably not quite as good, internet connectivity in Sweden and the Netherlands.

              What about the Korea-sized swath from DC, through Philly and NYC, to Boston? It's pretty densely populated with rich media consumers. Why not just in NYC, where only 10% of the fiber is even lit, and we're among the richest, hungriest media consumers on the planet? Could it be that broadband providers are limited by their bizmodel, defined by the regulations they lobby incessantly to retain? That their lazy management is more interested in the low-hanging fruit of overcharging for pay-per-view of the movies they own, rather than opening up the infrastructure to competition from every shop with real broadband, or P2P?
          • 25bps for $20? Poor lads. I hope, it is more along the line of 25Mbps. :)

            I think it is because the telco-market in the US has been fairly agressive, which didn't leave much room for investments in the future.

            The bandwidth we enjoy outside of the U.S is usually the result of previous "investments" in state monopolies. The investment resulted in having a good infrastructure. Overspec'ed, just to telephone with.

    "If you want to reach the whole population, you have to make sure it can scale up."

    I thought with the current schema the internet uses it was allways setup to scale and allow for redundency, where one section can do down and a new one can take place. Or new networks could easily be added, and expanded off of.

    Even new technologys like P2P and torrent etc were able to come out, still functioning correctly with the internet with no changes.

    Maybe they mean the ability for the technology to scale up, meaning situations like the IPv6 would not be such a consern. But then again IPv6 is a huge change to the entire structure of how the internet functions.

        However, if the site in question does not support IPv6 packet formats, then an IPv6-only host would not be able to contact the site, as the site would not be able to form the IPv6 packets back to the requesting host.

        So either the requesting host would have to have an IPv4 address available to it (either directly or via NAT), or the requesting host would be unable to access the site.

The knowledge there on how it works on a grander scale is helping to tune and shape the works that come out of places like Cisco and Nortel. Thier code gets production tested first on Abilene and then to the big networks. We also get the new big routers to test with usually before anybody else does. If you go look at Abilene's [internet2.edu] website, you can see from the network graphic that it's pretty busy.

              Interestingly enough there seems to be a moving away from expensive ATM connectors to cheaper 10GigE connections. Our state network has just converted the backbone to GigE, and I expect that our connection to Abilene will change to that soon as well. I think ATM for medium length hauls will die out, only to be used on extra long hauls like across contries and oceans. I can see the big networks doing this to to cut down on costs and brainpower.
