Next-Gen Broadband Primer 274

Posted by Zonk from the faster-and-faster dept.
Aaron writes "Broadband Reports has a good read on the real deal behind next generation broadband deployments. In four years: half all Verizon DSL users should have fiber, half of all SBC subscribers should have 10-20Mbps DSL, and one tenth of all BellSouth customers should have 50Mbps DSL. At the same time cable companies should begin deploying DOCSIS 3.0 technology in 2006, eventually bringing 100Mbps speeds to end users."

    BBR: While we're only starting to see DOCSIS 2.0 deployment, and the higher speeds it can bring (Adelphia & Cox 15Mbps), DOCSIS 3.0 should only be a few years behind. Do you see the cable industry having any trouble keeping up with these bell plans?

    DB: The "15 meg" speeds Cox is offering where they compete with Verizon fiber are mostly advertising. It's really 38 meg shared among 100 or so users, the same speed as the current services advertised at as 3 and 7 meg. That's too much oversubscription to deliver 15 meg most of the time, if even 5 or 10 people are downloading on the node. To regularly get past today's 5 meg or so, you need to bond more channels, which is what DOCSIS 3.0 offers.

    DOCSIS 3.0 is real, mostly agreed, and the key vendors have the details and are making equipment for 2006. It's a shared 160/120 or higher, easily expandable to a shared gigabit. Real speeds to users will often be 20-50 megabits. It was developed to compete with higher speed DSL in Asia. Early in 2005, the U.S. cable companies realized Verizon was serious about
    fiber, and pushed CableLabs and suppliers (Cisco, Motorola, Arris, Broadcom) to get DOCSIS 3.0 ready for the U.S. ASAP, and 2006 is realistic
    with some pricey gear.

    I will believe it when I see it. Depending on your home area, overselling of bandwidth can be a real problem. I have seen both DSL and Cable
    providers routinely claiming speeds "up to". 5mpbs but real speeds are usually in the 3mbps range. Of course, the cable/DSL providers claim that "few sites allow you to take full advantage of your maximum bandwidth", which is a pile of horseshit, plain and simple. 92% of their userbase will believe that while the 8% that don't the broadband companies don't
    want on their networks anyway.

    While highspeed connections are great, I want to know where this backend bandwidth is coming from and who's paying for it? T3+ downstream speeds for only a tiny fraction of the real cost? I will be that 30+ megabits is nothing more than a pipe dream/marketing ploy. The real speeds we will be seeing are in the 10 to 15 range for "premium" members and will likely come with heavy "unadvertised". monthly caps. They want you to see webpages come up lightning fast (which happens at 1mbit) but they don't want you to actually see 10GB of torrents come in a day. They will still be catering to the 92% of their userbase that is the "mom and pop e-mail
    and CNN checkers". The people who would really be excited about paying higher fees and getting the advantages of the massive bandwidth will end up with ToS violation warnings and slower than expected speeds.

          Perhaps in your neck of the woods, but where I live, it's a different story.

          Shaw (Edmonton) just upgraded my cable modem (at no charge), and I'm getting a consistent 6Mbps down and 1.5Mbps up.

          Before the upgrade, I was getting 1.8Mbps up and 350K down. Their rates haven't changed (I'm still paying the same $40.00 per month - including modem rental.)
          • Here in just a province away in B.C., for about that price ($48+ after tax), I get 1.5Mbps down and 512K up with telus. Or I could choose delta cable (no shaw in my town... probably the only non shaw area) and get roughly the same speeds with a 10 gig/month cap (STRICTLY enforced... you go over, you pay... and it's not cheap).

            Telus gives me 2 ips, so I chose them (besides, they don't seem to care how much I download. A few years back however, I got 4Gbps for the same price.

      The two technologies involved seem to be ADSL 2+ and VDSL. They both have their merits but ADSL 2+ can be rolled out by upgrading current ADSL 1 instalations. VDSL however requires Fiber-to-the-street, thus requiring a much larger investment.

        Well this has always happened. For example when Modem speeds went at 1200bps we dared to use 8 bit ascii with special charactors such as lines and block charactors. Then at 2400bps we pushed it further with color ANSI so we could have colored text, at 9600bps we would use a lot of those advanced charactors and colors that filled the screen, then at 14.4k we started to use vecor based graphics (Like RIP Script and whatever Prodigy used at the time) then at 28.8k we started to have bitmapped graphics, 56.6k we pushed to digital audio content. And then broadband we have more realtime audio and vecor based animations (flash) and as Broadband speeds increased we have more realtime movies increasing audio quality. and as speed increase you will see more things happining in realtime. Which will make HDTV's and Telephones Obsolete. Perhaps if we can get Broadband at 1gbs or faster we will have enough technology for 3d stuff.

        Sure a lot of traditional technologist call this stuff bells and whistles and fluff. But in reality computers are here for our own benefit. So if we want to use our spare bandwith and cpu cycles for our enjoyment we should be able to.

      Actually, ubiquitous speeds on the order of 100 Mbps will change everything.

      Right now, with a one-megabit DSL connection, it's possible for me to use a Terminal Services client at home to run basic apps like Outlook and Perforce on my machine at the office. It's slow, clunky, and not especially pleasant, but it works, and it beats the hell out of juggling multiple email clients (and .PST files). Even things like streaming video almost work.

      At 10 megabits/second, this process will still be slow, but not all that clunky, and a lot less unpleasant. More apps will live on my machine at work, without having to be duplicated at home.

      At 100 megabits/second and up, the distinction between remote computing and local computing will disappear entirely for most users. Software and services subscription models for commercial applications will actually make sense for PC users for the first time. The client operating system -- be it Windows, Linux, MacOS, what-have-you -- will shrink to almost zero-importance.

      And Microsoft will either be bankrupt or they'll own the inner planets, depending on whether the entire company goes down with the sinking Windows/Office ship.

      Since the entire Internet will be one huge client-server network at that point, worms, viruses, and malware won't be a concern for most users. Monopolization will be. Whose machine is going to run and maintain 99% of your applications? If you think you're married to your software vendor now, you haven't even met her daddy yet.

          Sure, in their current incarnations. This a pie-in-the-sky kind of prediction to begin with... we are multiple decades away from widespread, economical 100-megabit access. Almost nothing will look or work like it does now. My point was, the change is going to be a bigger one than just the usual "more games/movies/pr0n" commenters were suggesting.

At that point it was obvious that we're only a couple of orders of bandwidth-magnitude away from not caring where our apps live.
          • we are multiple decades away from widespread, economical 100-megabit access.

            Today, 1 Megabit broadband is slow. 5 Mbit is the norm. 2.5 mbit is about what I normally expect when downloading a popular torrent. 10 Years ago (lets see, this is '05 so that would be '95) I had under 56k speeds/ That is a 50x increase in under 10 years. That means that 100 Mbit access is probably at most 10 years away, not multiple decades.

If I click on something, and it takes 150 ms for the packet to reach my "real computer" and then 150 ms for it to come back, then that's almost 1/3 second percieved lag whenever trying to do anything. Imagine trying to play Quake on a remote system. No matter how much bandwidth you've got, the game just won't run right with 1/3 second lag.

      You're missing the point (as is probably most everyone else here) on why the TelCos are doing this buildout. Once they hit 25 Mbps, they can start offering full quality HDTV service over the lines and compete with cable like never before. They will be able to supply Phone, Internet and Video on one service. That is their main reason. 20 Mbps for TV, 5 mbps for internet and ~11Kb for phone. If they really want to have fun, they can start doing Video Phones on their networks for about 1Mbit total.

      Chanel Changing times for the TV will be a little bit longer than with DTV, but that is because it is using the multicast on the network and has to tell the router/central server to send it the bits. However, this will mean a third competitor in the Cable/Satelite market. It will also mean a second proper competitor in the broadband market.

      Once they get above 25Mbps, then they can start increasing the quality of the TV they offer. 15-20 Mbps is really the minimum you need for HDTV. ~45 Mbps will pretty much garuntee you great quality no matter what is on the screen.

      One final comment on the prices of OC-3s. The TelCos are generally some of the companies that own various backbones that the internet here in the US is made of. They can charge themselves whatever they want for access.

      I'd love to be able to set up WebDAV or have streaming video from home to wherever I am. I can't do it because most providers (and all the providers in my area) don't have fast enough upstream speeds and don't allow servers

      The justification of lack of server support is twofold. First it's that you shouldn't make money off of their service unless you overpay for a "business" connection. (Which is BS. Bandwidth is bandwidth.) The se

        Sort of. I don't know of any asymmetric pipes, so broadband providers must have tons of unused upstream bandwidth. As you say, they're only limiting your upload speed so they can make you pay more.

        I'd love to have my own leased line and not have to deal with an ISP, but even T1s are very expensive.

    Has anyone considered the implications of a DDoS involving a zombie army of machines with 100 mbit uplinks? This could spell disaster for just about everybody except those with the absolute fattest pipes. It takes an awful lot of hosts to swamp an OC3 now, but that's with hosts that rarely have a half megabit uplink, if that. It would be frighteningly easy to swamp the heavy links with a few 100 mbit links.

    That is, of course, unless the bigger pipes grow at a rate proportional to the smaller ones. That also assumes symmetrical links for the home connections. Oh the irony of a 100 mbit / 128 kbit connection.

      Bingo. That's exactly the kind of scenario you will see. Broadband providers don't want you providing content to the internet, they want you consuming content. The upstream is only to provide requests for content.

      If you want a symmetrical 100mbit connection, try banding together a couple of T3 lines. Good luck paying for it!

    The heck with download speeds, I want more upstream speed. I'm in an SBC area very close to a Remote Terminal, but in an older neighborhood with no alleys and lots of wooden fences which is unlikely to get fiber. Right now I get 512K up out of a possible (with regular ADSL technology) 640K. If they use VDSL, that can go as high as 2.3M up. I think I'll be happy if I can get 1.5M (esentially a full T1) up.

    What I'd like to see is better utilization of bandwidth within the cable/DSL network infrastructure. It costs cable/DSL providers MUCH less to provide high speed connections between customers in the same local topology.

    If you had 100Mb/s to everybody within your local area it would make things like high speed videoconferencing or sharing of high bandwidth content between friends and family VERY fast.

    Problem is that current caps on cable/DSL lines dont' descriminate between transfers between two people on the same cable/fiber segment and going out beyond the border router and down that T3/OC-3 or whatever out to the commercial internet up provider. As a result you are capped at communicating with the person accross the street when you really could communicate with them at blazing speeds.

    It would be nice if they put 100Mbit to the end user -- but my personal experience with SBC and Verizon warns me to not believe all the hype. They regularly throttle connections -- and hosting any kind of service is typically a NO-NO. Thus they lost me as a customer (both residential and business grade).

    The sad thing is that they're just _now_ getting to this. I've had 10Mbit (symmetrical) for many, many years now ($50/mo) through a wireless connection. Yes, that is a solid 10Mbit and I regularly see 800-900K/sec (up or down) if the remote site can handle it. A good test has always been downloading something from Apple. :)

    Yeah, I said upload. My ISP has no issue with me hosting my own website, email server, heck camera video feeds too ... at home no less. They're towers used to be at 45Mbit and were since upgraded to 100Mbit (or better I believe) with the option to upgrade my antenna coming next month (to 45Mbit -- at my expense for the equipment, but I *own* it then :).

    Why are the bells lagging to badly? Sure, the wireless connection (being shared) doesn't *always* give 100% throughput as many others may be tapping it hard at the same time; 8pm isn't a good download time, but gaming isn't a issue... (~10-12 ping on Quake or better -- yeah, that's me you love to hate :).

    I will say that it is rock solid enough to have taken the POTS then ISDN line away from the Bells too -- all VoIP over here (through the ISP no less :). I can think of the last time my Internet went down -- it was about a week ago with golf ball sized hail falling from the sky. I was out for I believe 3 minutes, probably while a bunch of routers had to re-sync for whatever reason. Previous to that I can't remember.

    Yes, 911 works as expected [tested, thank you :]. Of course there is the cell phone -- and honestly it is in my head to go for the cell in an emergency. If both VoIP and cell fail then there may be bigger issues at hand -- and running down the street naked yelling "FIRE!, FIRE!" will certainly bring help. :)

    SBC trots this out whenever they want something from regulatory authorities. But they don't actually install it.

    Read this 1999 article about SBC's 'Project Pronto' [ebay.com]. " According to SBC, when the expanded deployment program is completed [in three years] customers will be able to receive minimum downstream connection speedsof 1.5 megabits per second, with more than 60 percent eligible to receive guaranteed speeds of 6 megabits a second." Right.

    SBC's new "Project Lightspeed" isn't about the Internet at all. It's just cable TV, implemented using Windows Media 9 over DSL using Scientific-Atlanta set-top boxes. The system doesn't use the Internet at all. It has its own infrastructure, which is a Microsoft-implemented multicast implementation.

    It's not about Internet access at all. All you can get is what they want to send you. Lightspeed will block access to Internet video. [64.233.179.104]
