The rest of the story? http://www.usatoday.com/tech/products/services/2008-04-20-internet-broadband-traffic-jam_N.htm By 2010, the average household will be using 1.1 terabytes (roughly equal to 1,000 copies of the Encyclopedia Britannica) of bandwidth a month, according to an estimate by the Internet Innovation Alliance in Washington, D.C. At that level, it says, 20 homes would generate more traffic than the entire Internet did in 1995. How many folks remember InternetMCI's lack of capacity in the 1990's when it actually needed to stop installing new Internet connections because InternetMCI didn't have any more capacity for several months.
I've been on the side arguing that there's going to be enough growth to cause interesting issues (which is very different than arguing for any specific remedy that the telcos think will be in their benefit), but the numbers quoted above strike me as an overstatement. Let's look at the numbers: iTunes video, which looks perfectly acceptable on my old NTSC TV, is .75 gigabytes per viewable hour. I think HDTV is somewhere around 8 megabits per second (if I'm remembering correctly; I may be wrong about that), which would translate to one megabyte per second, or 3.6 gigabytes per hour. For iTunes video, 1.1 terabytes would be 1,100 gigabytes, or 1,100 / .75 = 1,467 hours. 1,467 / 30 = 48.9 hours of video per day. Even assuming we divide that among three or four people in a household, that's staggering. For HDTV, 1,100 gigabytes would be 1,100 / 3.6 = 306 hours per month. 306 / 30 = 10.2 hours per day. Maybe I just don't spend enough time around the "leave the TV on all day" demographic. Is that a realistic number? Is there something bigger than HDTV video that ATT expects people to start downloading? -Steve _______________________________________________ NANOG mailing list NANOG () nanog org http://mailman.nanog.org/mailman/listinfo/nanog
